Meyer Hydraulic Fracturing Software Users |
| Subject: |
Meyer 2012 Software Suite version 5.70 |
| Date: |
December 2011 |
Dear Users:
We are pleased to announce the Meyer 2012 suite of software
version 5.70 dated December 2011.
Meyer 2012 is compatible with 64-bit and 32-bit versions of
Windows 7 and Windows Vista, and with 32-bit versions of
Windows XP SP3 and Windows Server 2003. The
minimum system requirements are listed
in Section 1.2 of the User’s Guide. See
the Meyer Fracturing Software User’s Guide
Section 1.3 for additional instructions on installing the Meyer
Software.
To run the software, current users must upgrade their license key by
running MKey and opening their
company-specific key file (sent separately via email). New users must
attach the enclosed hardware license key to their computer.
Meyer 2012 represents over a year’s
worth of development, and has a number of exciting new features. Here
are some of the highlights. (For details, see the section “Meyer 2012
RELEASE1” below.)
Midfield Fracture Complexity.
In Meyer 2012, MShale has gained the capability to model time
dependent midfield fracture pressure decline for the fracture
network.
It has been observed (e.g., Weijers et al. (2002), Weng
(1993), and Jacot et al. (2010)) that complex fracture
behavior may occur when fracturing highly deviated and/or horizontal
wellbores. MShale’s new Midfield
Fracture Complexity option enables users to model this
behavior using the methodology set forth in Meyer et al.
(SPE 140514).
3D Wellbore Model.
The Meyer 2012 wellbore model has been greatly enhanced to
account for wellbores deviating in 3D space. The new wellbore model
allows the user to enter 3D deviation data (inclination, azimuth,
northing, easting) to accurately describe wells drilled with modern
directional drilling techniques.
Native 64-bit Support. The
Meyer Software is now available in two builds: a traditional 32-bit
build, and a new 64-bit build that runs as native 64-bit executables
on operating systems supporting this capability. The 64-bit
version of the software is faster than the 32-bit version, and it is
capable of handling a much larger amount of data in MView.
Both versions of the Meyer Software are built from a single code
base, so their file formats, preferences, and databases are
compatible, and there should be little to no difference in their
simulation results. (We have done extensive testing to verify that
this is true; see the detailed
changelog.)
Both versions of the Meyer Software are included on the Meyer CD.
The Meyer Setup program will automatically install the 64-bit
version, rather than the 32-bit version, if it detects that it is
running on a 64-bit operating system. (This behavior can be
customized by each individual user’s system
administrator or IT department.)
Plot Print Preview. All
Meyer plots have been enhanced to support a command. This should greatly
simplify the task of fine-tuning the layout of a printed set of plots
(e.g., it will make it much easier to put text blocks and legends in
the exact right spot).
Additionally, the plots now allow the user to select a printer at
time using the standard Windows
printing workflow, rather than requiring a visit to .
Translated Installer. The
Meyer Setup program is now translated (localized) into the same
language as the apps on its CD. (For example, the installer for
Russian Meyer 2012 will now appear with a Russian user
interface.) This corrects a long-standing gap in our support for
running the Meyer Software in users’ native
languages.
TCP/IP Data Acquisition. The
Meyer Data Acquisition program has been enhanced to allow data
acquisition via a direct TCP/IP link (i.e., a link running no
particular application protocol but rather simply dumping raw data).
This feature should be especially useful when working in newer data
vans without a reliable serial port connection.
It is important to emphasize that these are just the highlights, and
that Meyer 2012 features many other enhancements, not listed
here, that are called out in the detailed
changelog. (For example, many input screens have been enhanced
with spreadsheets for easier data entry, replacing the old-style
individual form controls.) The Meyer 2012 release includes
over 135 enhancements and bug fixes.
We have put a lot of effort into ensuring its quality and stability,
and we hope that you will find it our best release yet.
Please do not hesitate to contact me with any questions.
Sincerely,
Bruce R. Meyer, Ph.D., P.E.

We are pleased to announce that Meyer 2012 is now available in
two builds: a traditional 32-bit build, and a new native 64-bit build.
This 64-bit build runs the Meyer Software as native 64-bit executables on
x64 versions of Windows 7 and Windows Vista. (#2243)
Both versions of the Meyer Software are built from a single code base,
so their file formats, preferences, and databases are compatible.
The 64-bit version’s simulation results have been
extensively cross-checked against the existing 32-bit (x86) version, and
any discrepancies have been noted and corrected during development (e.g.,
#2592).
The 64-bit version of the Meyer Software is marginally faster than the
32-bit version. Much more importantly, it is capable of handling a much
larger amount of data in MView. We are looking forward to the new
features we expect to be able to add to future Meyer Software releases
now that we have 64-bit support.
Sysadmin’s Corner: Both
builds of the Meyer Software are included on the Meyer CD. The Meyer
Setup program will automatically install the 64-bit version, rather than
the 32-bit version, if it detects that it is running on a 64-bit
operating system. To prevent installing the 64-bit version, create a new
CD image containing only the 32-bit version (or at least, with the file
mfs_amd64.msi removed). Contact Meyer Technical
Support if you have any questions.
All Apps
[Enhancement] Added more settings to the command.
In particular, this command now resets spreadsheet column positions,
splitter positions, and last selected tabs (for input screens with
multiple tabs) to their default values, in addition to any settings
affected in prior versions. (#2550)
[Enhancement] All apps with simulators now show the date of the
last run output data on the menu.
(#2562)
[Enhancement] All Meyer apps now support data entry and text
file import using Unicode fullwidth and national digit shapes. This
is especially important for users running Chinese and East Asian
versions of Windows. (#2569)
[Enhancement] Many input screens across the apps have been
modernized and made easier to use by converting them to use
spreadsheets. This especially eases copying, pasting, sorting, and
transformation of data in the case of screens with many inputs.
(#1961)
[Enhancement] is now
translated (localized) into the same language as the apps on its CD.
(For example, the installer for Russian Meyer 2012 will now appear
with a Russian user interface.) This corrects a long-standing gap in
our support for running the Meyer Software in users’ native languages. (#2540)
[Enhancement] Progress bar windows (e.g., for importing a text
file) now open on the same monitor as their parent window on
multi-monitor configurations. Previously, these windows would open on
an arbitrary monitor. (Similar symptoms to #2518, but with disjoint code.)
(#2486)
[Enhancement] The
list now offers the user a choice about whether to remove an
unreachable file from the list, rather than simply removing it. This
will help users who try to open on flash drives or disconnected network drives (e.g.,
offline laptop). (#2529)
[Enhancement] The screen now
remembers the user’s last selected sort order
and scroll position. (#1779)
[Change] Starting in early 2010, a number of commercial
virus scanners began flagging bits and pieces of Meyer Setup (typically
the README) as a “generic virus/trojan.” Meyer 2012 Setup has a number of
non-functional changes intended to ameliorate this. (#2503)
It is important to note that none of the affected Meyer-supplied
setup discs or packages actually contained a virus; this was purely a
false positive caused by automatic virus scanner updates (after our
releases) and/or virus scanner heuristics.
Please report any future virus scanner warnings involving Meyer
Setup directly to Meyer Technical
Support.
[Fix] Fixed box and menu sidebar text appearance on
Windows Vista and Windows 7. By default, this text was black
with a black drop shadow, which made it difficult to read.
(#2480)
[Fix] The Simulation Data Windows lost their settings (e.g.,
column order and column hidden/shown preferences) whenever the user
changed the computer’s screen resolution.
(#2509)
[Fix] When error checking screens with multiple tabs (panels),
not all tabs were error checked when simply opening and closing the
screen. The user had to manually visit each tab in turn to find any
errors in the data. This could be very frustrating when trying to
track down errors reported by the
command. (#2542)
Databases
[Enhancement] New Proppant Database vendor: CRS Proppants. (#2597)
The databases provided with the software are based on sound
engineering practices, but because of variable well conditions and
other information which must be relied upon, Meyer &
Associates, Inc. and its database suppliers make, no warranty, express
or implied, as to the accuracy of their data or of any calculations or
opinions expressed therein or derived therefrom. You agree that
Meyer & Associates, Inc. and its database suppliers shall not
be liable for any loss or damage whether do to negligence or otherwise
arising out of or concerning such data, calculations or opinions.
[Fix] The system database entries for proppants 0000
(100 Mesh Sand for Fluid Loss) and 0001 (20/40 Jordan Sand)
contained data that triggered validation errors upon editing these
entries in the user database. (#2590)
Plots
[Enhancement] All Meyer plots have been enhanced to support a
command. This should
greatly simplify the task of fine-tuning the layout of a printed set of
plots (e.g., it will make it much easier to put text blocks and legends
in the exact right spot). (#2523)
[Enhancement] Pressing Escape while adding a text block now
cancels adding the text block. Previously, there was no way to cancel
adding a text block. This fix also applies to most movable objects on
the plots, including objects that become movable in Graphical
Arrange mode (titles, legends, plot area, etc). (#2465, #2508)
[Enhancement] The screen now features a “Reset
default configuration” button to restore user
settings to the program’s initial defaults.
Previously, restoring these settings required manually editing the
Windows® Registry. (#2497)
[Enhancement] The plots now allow the user to select a printer
at time using the standard Windows
printing workflow, rather than requiring a visit to . (#2448)
[Fix] Clarified error message when opening files with an invalid
plot configuration. (Such files did not normally appear “in the wild,” but they could
be generated by users testing pre-release development builds of the
Meyer Software.) Previously, trying to open a file with an invalid
configuration would fail with the cryptic error message “Unspecified error encountered while reading
temporary file.” (#2488)
[Fix] Fixed access violation crash when deleting an app’s default plot configuration (.plt
file, e.g., mfrac.plt) with the app open. This also
occurred if the .plt file was locked (e.g., by a virus
scanner) while the app was starting up. (#2491)
[Fix] Fixed confusing user interface: bar charts allowed the
user to configure the plot to show Stage Number, Percentage, or Unit
Values on the legend, but this option had no effect. This “Chart Legend” option is now
disabled for 2D and 3D bar charts. (#2547)
[Fix] Fixed the occasional appearance of double gridlines
(caused by floating point roundoff error) in plots with both left and
right Y scales. (#1670)
[Fix] For plots with hidden information display boxes, clicking
and dragging in the upper left corner of the plot’s data area would allow the user to manipulate a
phantom drag rectangle. (“Information display
boxes” are programmatic readouts of simulator
results, e.g., the ISIP readout in MinFrac.) (#2195)
[Fix] Mouse coordinates on bar charts were displayed using the
curve colors, when they should have been using the filled area colors.
(#2472).
[Fix] Mouse coordinates: The text “У(сл)” and “У(сп)” was displayed in the
wrong colors for the Russian build. The code to draw the coordinates
was assuming that the Russian translations of “YL” and “YR” had the same number of
characters as their English originals. (#2470)
[Fix] Plots containing more than one sub-plot (e.g., MFrac ) allowed
the user to specify a setting for the Plot Layout option, but then
ignored it. The radio buttons for this setting are now disabled.
(#2463)
[Fix] Toggling the in plots containing more than one sub-plot (e.g.,
MFrac ) now keeps the mouse coordinates setting in sync
between all the sub-plots. Previously, these plots would show the
mouse coordinates on all sub-plots if any sub-plot had them set to
“On,” so removing them
required manually setting them to “Off” for each sub-plot. (#2608)
Spreadsheets
[Enhancement] All spreadsheets now have a default (non-blank)
value for and
(under ). These options have
existed for several releases but the old default values were blank, so
most users did not benefit from them. (#2519)
[Fix] Changing spreadsheet preferences (e.g., row colors) in one
app now applies changes immediately across all apps. (#2520)
[Fix] did not
function properly in spreadsheets that were set to Row Select mode
(e.g., the new Tubing and Casing Database spreadsheets in MFrac’s
screen). Instead of copying the whole row, this command would only
copy one cell of the row. (#2527)
[Fix] The (Ctrl+D)
command would overwrite the data in any selected cells, even those
that were supposed to be non-editable (grayed). (#2563)
[Fix] The
screen now shows only the editable rows from the spreadsheet selection.
Previously, this screen would show all selected rows—including
non-editable rows—even though its changes only applied to the
editable rows. (#2484)
[Fix] was missing from
the spreadsheets’ right-click context menus.
(#2521)
[Fix] Spreadsheets now give the user feedback (e.g., adding or
removing rows from the spreadsheet; changing a background color)
immediately upon making a change in a drop-down list. Previously,
spreadsheets would not react to the user’s
input until the user pressed Enter or OK, or moved the selection to
another cell. (#2506)
MFast
MFrac
Many of the fixes in this section also apply to
MShale, MPwri, and MWell.
[Enhancement] Added buttons to the Casing, Tubing, and Coiled
Tubing tabs in to
access the respective databases. (#2479)
[Enhancement] The Meyer 2012 wellbore model has been
greatly enhanced to account for wellbores deviating in 3D space. The
new wellbore model allows the user to enter 3D deviation data
(inclination, azimuth, northing, easting) to accurately describe wells
drilled with modern directional drilling techniques. (#1724)
The new code supports the five standard methods for wellbore
surveying calculations:
-
Average Angle Method
This method models the well path between two stations as being
along a straight line whose length is the measured depth difference
between the two stations and whose inclination and azimuth angles
are the average of the stations’
values.
-
Balanced Tangential Method
This method models the well path between two stations as two
line segments, each having a length that is half the measured depth
difference between the stations. The first segment has the
inclination and azimuth angles of the first station, while the
second segment has those of the second station.
-
Minimum Curvature Method
This method is a refinement of the Balanced Tangential Method
where the two line segments are replaced by a circular arc lying in
the same plane as the line segments, but where the arc length is
equal to the difference in measured depths of the stations. The
Meyer implementation is based on the formulation of Sawaryn et
al. (See SPE 84246.)
-
Radius of Curvature Method
This method models the well path between two stations as a
circular arc lying on a vertical plane which is then curved along a
horizontal circular arc.
-
Tangential Method
This method, like the Average Angle method, models the well path
between two stations as being along a straight line whose length is
the measured depth difference between the two stations. In the
Tangential Method, this line’s inclination
and azimuth are those of the second station only.
[Fix] Fixed an off-by-one error in the
simulator where the stage properties from the n+1th stage could be used to compute bottomhole
data. (#2558)
[Fix] Fixed excessive padding inside the legend border when
printing plots when the plot windows were set to a very small size on
the screen. (Example: Reduce MFrac to 200×200 pixels; Tile
Horizontally; print all plots.) (#2603)
The fix for this bug should also make it easier to position legends
precisely when printing. The buggy code had a side-effect of
guaranteeing that legends would appear in a different place on
the printer than they did on the screen, which made the printed
copy’s appearance difficult to
predict.
[Fix] Fixed erroneous Tab key behavior on the screen with Fluid Inlet set to
Surface. (#2462)
[Fix] Fixed excessively large propped width at closure due to
improper extrapolation. (#2591)
[Fix] Fixed infinite loop (and resulting 100% CPU crash) when
printing contour plots with the plot large (e.g., maximized) on the
screen and small (e.g., all plots on one page) on the printer.
(#2605)
[Fix] Fixed non-increasing time step and/or
time going backwards in the fluid loss layers simulation. (#2557,
#2560)
[Fix] Fixed printing when multiple plots were open and the
Graphical Treatment Schedule was in the foreground. (#2525)
Depending on the exact version in question, this bug typically
caused one of the following:
- Access violation crash;
- Unable to print anything except a single window at a time (like
MView #2483, which was fixed in a Meyer 2010 service
release);
- The options to “print all plots” produce blank pages.
[Fix] Fixed radio button keyboard navigation on the .
(#2507)
[Fix] Fixed scaling and other user interface glitches while
dragging the Restart Time line in the Graphical Treatment Schedule.
(These were more noticeable in Real-Time mode as opposed to Replay
mode.) (#2514)
[Fix] Fixed simulator coding errors which allowed the pay zone
location to influence the proppant transport solution. This was mainly
noticeable when the pay zones and perf zones were not overlapping.
(#2575)
[Fix] Fixed simulator coding errors which could result in a
negative average fracture permeability (and negative fracture
conductivity/negative dimensionless conductivity). (#2581)
[Fix] Fixed spurious concentration spikes in
stages with no proppant (caused by floating point roundoff error in
stage boundary detection). (#2572)
[Fix] Fixed total leakoff coefficient (simulator output value)
for ellipsoidal fluid loss. Also affects MPwri. (#2593)
[Fix] Inactive perf zones could influence the
Wellbore Hydraulics simulation output. In particular, an inactive perf
zone with an invalid center-of-perfs measured depth (that would not
pass error checking if the zone were active) could cause incorrect
output. (#2526)
[Fix] In ,
error checking did not always display the appropriate tab (i.e., the
tab with erroneous data) when the user selected the Change button.
Thus the user could get an error message, select Change, and then be
left in an unrelated part of the Wellbore Hydraulics screen with no
hint from the program about how to find the erroneous data.
(Also fixed a similar bug in the screen.)
(#2541, #2559)
[Fix] New MFrac files now default to Empirical proppant settling.
The default had inadvertently been switched to Convective Transport
since Meyer 2008. (#2604)
[Fix] Perf zone and pay zone lines did not appear in the plots
the first time the simulator was run after an upgrade. Also, if you
edited the zone depths, the lines would appear in their old locations
(which could be outside of the bounds generated by auto-scaling) the
next time the simulator was run. After running, the lines would move
to the correct locations. (#2602)
[Fix] Perfs in horizontal wells are now visible on the profile plot. (#2546)
[Fix] On the screen,
the defaults for Base Fluid, Reservoir Lithology, and In-Situ Fluid
had inadvertently changed for new files starting in Meyer 2008.
The correct defaults are Water, Sandstone, and Light Oil, but in
Meyer 2008 through Meyer 2010 these were changed to Binary
Foam, Anhydrite, and Medium Oil.
The same bug also occurred in MPwri’s screen, except that the default
In-Situ fluid was supposed to be Water, and had changed to Gas.
This bug only affected new files. A simple workaround was to check
and adjust the settings in the and screens
before running the simulator. (#2606)
[Fix] The Graphical Treatment Schedule now longer draws grid
lines and incoming real-time points underneath the legend, not over it.
(#1448, #1450)
[Fix] The Graphical Treatment Schedule
would not show data from MView’s “Additional Parameters” under the
following circumstances: (#2545)
- Opening an MFrac file before opening the corresponding MView
file;
- Opening an MView file, opening the corresponding MFrac file, then
returning to MView and selecting different Additional Parameters;
- Opening MFrac and using the default Most Recently Used file opened
by MFrac at startup (i.e., never performing after MFrac connects with
MView).
[Fix] The error checking was broken for negative rate stages when
Flowback was enabled. (The error checks were improperly rejecting
these stages.) (#2531)
[Fix] The
wellbore schematic plot now updates after deleting rows from the
Casing, Tubing, and Restrictions tables using the Delete key.
(#2230)
[Fix] Upon opening the , the schedule would delete any proppant codes that
didn’t have a corresponding entry in the user
database. When this happened, it was impossible to tell what proppants
had been used in the file before the Treatment Schedule deleted them,
creating a chicken-and-egg problem for anybody trying to recover the
file to its original state. (#2517)
Normally this bug had little impact because .mfrac
files carry copies of any proppant database entries used in their
Treatment Schedule, and these entries are automatically imported into
the user database upon opening the file. However, the bug could cause
trouble in two common scenarios:
- The relevant database entries were deleted with the file open,
and the file was subsequently saved;
- User running with a read-only proppant user database.
[Fix] did not
recalculate the Wellbore Reference Depth and BHP Reference Depths if
the user changed the data in the Deviation table, then immediately
closed the Wellbore Hydraulics screen without looking to see if the
depths had been properly recalculated. (#2589)
[Fix] When the
injection method was set to Annulus, the simulator was not error
checking the Tubing table. This caused an access violation crash if
the Tubing table happened to be empty in a case with injection down
the annulus. (#2539)
MinFrac
[Enhancement] Overhauled the user interface layout for the
Step Rate “Enter ΔP Fric and ΔP
Frac” screen. (#1660)
[Enhancement] Removed pressure curve data based minimum and
maximum value constraints from items in (especially the Slope Lines points) where basing the
minimum and maximum values on the pressure curve data was not helpful.
(#2614)
[Enhancement] The screen now highlights any cells with
different values compared to . (#2516)
[Fix] After importing a file in , the History Match Data
toolbar icon remained disabled until the user closed and reopened
the Options screen. (#2600)
[Fix] Attempting to pick up a point with the mouse set to Zoom
mode, then trying to switch out of Zoom mode using the F4 key (while
still holding the mouse button) caused a malfunction. (#2471)
[Fix] Derivative curves on regression plots could trigger plot
scale corruption and/or random memory corruption if there was no data
in the curve (i.e., if the curve became empty—for example, by
clearing Real-Time data in memory). (#2513)
[Fix] Fixed an access violation crash when using the “print all plots in all screen windows” command from the Wizard. (This crash was present
in all previous versions of the software; however, Meyer 2010
introduced a secondary bug which made the crash impossible to
reproduce. The relevant code was corrected in Meyer 2012.)
(#2524)
[Fix] Opening
would (unintentionally) close the report, but only if one or more plots
were also open. (#2515)
[Fix] Select and Zoom mouse modes were improperly disabled
(grayed) in the right-click context menu for the Step Down Diagnostic
plot. (#2598)
[Fix] Switching tabs in the Wizard made the Regression History
Match tab forget the user’s settings for the
GDK, PKN, and Ellipsoidal drop-down lists. (#2543)
[Fix] The calculations for the Regression History Match curve
were wrong when the input units for Time were set to something other
than minutes. (#2582)
[Fix] The
command was disabled in . This command is now enabled. (#2485)
[Fix] When the user changed the , the diagnostic plots would not update their information
on the plot using the mouse. (#2325)
MProd
[Fix] Certain spreadsheet columns could interfere with each
other in the and
screens. Resizing or moving one such column would cause the other
column to be resized or moved upon reopening the screen.
(#2556)
[Fix] Fixed drawing glitch in the “Optimum Fracture Performance Curves” plot legend when unchecking the “Optimum Fracture Performance Curves” option in the Design Optimization simulator.
(#2588)
[Fix] Fixed incorrect simulator error
messages for “CfD number of
sub-divisions” and “proppant number of sub-divisions.” (#2494)
[Fix] The Design Optimization simulator produced incorrect
dimensionless fracture conductivity (CfD) output when the
number of sub-divisions exceeded 994. (#2587)
[Fix] The History Match simulation was not
implemented for an unfractured, horizontally oriented well.
(#2498)
[Fix] The screen did not recalculate its CfD
values properly on , , , and .
The code would only recalculate the value for the first selected row,
not any subsequent rows. (#2586)
[Fix] The ’s spreadsheet column widths were shared across all
apps, but the Calculator screen’s overall size
was stored separately per app. Thus the following sequence of steps
caused an absurd result:
- Make the Proppant Calculator very small in MProd.
- Close MProd.
- Open MFrac. Make the Proppant Calculator and its spreadsheet
columns very wide.
- Open the Proppant Calculator again in MProd.
(#2490)
[Fix] The simulator did not compute the Reservoir Pore Volume
and Initial Gas in Place if the user stopped a History Match, Closed
System simulation early. These values could be blank or out-of-date at
the bottom of the report. (#2617)
-
[Fix] The “Horizontal—No Fracture” tab could improperly allow the user to edit the
data when using the History Match simulator with a fractured,
single-case, horizontally oriented well. (#2473)
This bug affected cases that had been using the Production
simulator with either Base or Stimulated Case set to “Horizontal—No Fracture.”
If such a case were then changed to use the History Match
simulator, the Well Data screen would continue to interpret the
Base and Stimulated Case options, even though these options are
disabled in History Match.
[Fix] The “Horizontal—No Fracture” tab was visible when using the Design
Optimization simulator, even though Design Optimization does not use
any of the data on this tab. (#2473)
[Fix] When importing multi-zone Proppant
Transport data from MFrac (using the button on the screen),
MProd allowed the user to select more than one zone for import, but
only the lowest numbered zone would actually be imported. MProd now
limits the user to a single selected zone. (#2499)
When the “McGuire and Sikora Type
Curves” and “Optimum
Fracture Performance Curves” options were
unchecked in the Design Optimization simulator, the and Simulation Data Windows were missing from the menu.
These windows were supposed to be disabled (grayed), not hidden.
(#2537)
MPwri
-
[Enhancement] Improved support for very low injection rates.
(r40463)
-
[Fix] Fixed bounds checking error on (“Fluid Loss
Data: Hydro-Carbon Saturation is not within bounds”) when Hydro-Carbon Saturation (fraction) was
between 0.9 and 1.0. (#2568)
[Fix] Fixed incorrect BHTP and flow rate distribution as
efficiency approaches zero in limited entry mode for multilayer fracs.
(#2567)
[Fix] For 2D fracture geometry, the Fracture Fluid Gradient
option is now disabled upon entering the screen. (#2577)
-
[Fix] Saving a file with an Injectivity
Index plot open, then reopening the same file, would show the plot with
the wrong options.
Specifically, any Injectivity Index plot versus Time
would be converted to a plot versus Volume (but with the wrong
X axis caption), and any plot with the Leakoff Rate or Fracture
Length options selected would have these options disabled.
(#2552)
[Fix] Some of the Diagnostic plots were missing titles (i.e.,
there were no words on the plot). This also applied to the plot under . (#2573,
#2607)
[Fix] The Porosity plot on the input screen was blank and/or showed
the wrong data. (#2534)
-
[Fix] The Real-Time injection rate staging
was calculated incorrectly for cases with stages smaller than the
real-time data steps. (#2530)
This could cause a variety of problems, including preventing the
simulation from ever initiating a fracture.
-
[Fix] The simulator did not properly store its output for
particulates volume per unit area. The symptom was that the “Vol. Loss/Area” plot
(number 9 under ) was always blank. (#2564)
MShale
[Enhancement] Meyer 2012, MShale has gained the capability to model time
dependent midfield fracture pressure decline for the fracture
network.
It has been observed (e.g., Weijers et al. (2002), Weng
(1993), and Jacot et al. (2010)) that complex fracture
behavior may occur when fracturing highly deviated and/or horizontal
wellbores. MShale’s new Midfield
Fracture Complexity option enables users to model this
behavior using the methodology set forth in Meyer et al.
(SPE 140514).
The basis of MShale’s Midfield Fracture
Complexity simulation, as explained in the Meyer User’s Guide appendix M.8, is the idea that complex
fractures in the midfield region turn and twist, then re-orient in the
direction perpendicular to the principal stress planes. This creates a
high fracture pressure that does not diminish instantly when the
fracture is shut-in. The fracture gradient during pumping can be much
greater than the overburden stress gradient without creating horizontal
fractures in the far-field.
Weijers et al. state that “Mid-field tortuosity is recognized by a high
apparent ISIP and rapidly declining pressures during the first few
minutes of shut-in.” If you are seeing such
effects in your work on unconventional resources, you may benefit from
trying out this new MShale feature.
The Midfield Fracture Complexity feature is configured using the
MShale screen. (#2378)
[Fix] The Fracture Network (Width) plot and the 3D Plot with the
DFN option enabled were incorrectly showing the secondary fractures
when the number of fractures was set to zero. (#2595)
This affected cases using the “Cluster or
Complex Fractures” option and zero in any of
the “Number of ... Fractures” inputs on the Characteristics page.
MView
[Enhancement] Massive speedup of the screen. This screen should now appear almost instantly for
any size data set. Also greatly reduced MView’s memory consumption with this screen open.
(#2438)
[Enhancement] The screen now has a horizontal splitter bar so the user can
adjust the relative sizes of the data preview and column setup
spreadsheets. (#2464)
[Fix] Changing a data set from Real-Time to
Replay when the “Data File” checkbox was unchecked had no effect.
(#2553)
[Fix] Data set names containing an “&” (ampersand) character
now display properly in ,
, the menu, and the screen. (#1595)
[Fix] Disabling a data set, then changing the
parameters, could cause MView files to become unreadable with a message
about an “unexpected unit type.” (#2551)
(The version of MView with this bug fix can recover any files that
may have become corrupt due to the bug.)
-
[Fix] Fixed an unhandled exception crash when using
Meyer 2010 to upgrade an MView file created with the following
procedure: (#2561)
- Create the file using Meyer 2003 or earlier;
- Upgrade the file using any of Meyer 2003 SE through
Meyer 2009 (inclusive);
- Never edit the Parameters screen data (i.e., never open the
Parameters screen) in the intermediate version.
[Fix] drop-down lists were interfering with menu access keys
(Alt+R, Alt+P, Alt+S, etc). (#2489)
-
[Fix] MView was unable to open data sets where parameter #1
had no data, but the other parameters did have data. This made
certain .mview files unusable. (The symptom was a long
message about an “inconsistent number of data
points.”) (#2487)
[Fix] Pressing F4 now correctly cycles through all available
mouse modes in
mode. (#2461)
[Fix] Renaming a data set in , but not making any other
changes (i.e., not entering Setup), would not mark the MView file as
needing to be saved. (In other words, would not prompt the user to
save their changes to the data set.) (#2554)
[Fix] The “Clear All” button in
is now disabled if the Parameters spreadsheet is blank.
(#2505)
[Fix] The Browse () button once
again defaults to the folder containing the currently selected data
file. (#2493)
-
[Fix] The for
Concentration TSS and Concentration OIW was not properly stored in
the .mview file. MView could be configured to send
these parameters to MPwri, but followed by (e.g., by closing and reopening MView) would reset them
to “Not Available.”
(#2528)
[Fix] The menu could
open the wrong plot, or nothing at all, if the data for one of the
plots in becomes unavailable.
(#2613)
Meyer Data Acquisition
[Enhancement] Meyer 2012 introduces the ability to perform
data acquisition via a direct TCP/IP link (i.e., a link running no
particular application protocol but rather simply dumping raw data).
This feature should be especially useful when working in newer data
vans without a reliable serial port connection.
Data acquisition interfaces in frac vans are not standardized, so we
have chosen to implement the simplest possible “protocol” (acquiring or
sending raw data over a TCP/IP socket) first. We are open to
supporting more structured or more capable protocols in the future;
however, we need details about the protocols that are in use before we
can support them. Please contact Meyer Technical
Support if your data van is running a TCP/IP-based acquisition
protocol that is not compatible with this new version of Meyer Data
Acquisition.
Information Security: The data transmission
in this new protocol is not secure: not encrypted, not authenticated.
If you are using Meyer Data Acquisition to send your frac data across
the Internet, anyone along the way could eavesdrop on your data or
alter data being sent to you. Please consider using add-on encryption
such as a VPN, an SSL/TLS tunnel, or an SSH tunnel if you are
performing data acquisition across the Internet or any other insecure
network.
These issues are much less of a concern when the data is staying
within the job site and only incidentally traveling via LAN or local
radio link (WiFi).
[Enhancement] Meyer Data Acquisition now auto-detects COM port
names and descriptions (for serial and modem ports) and displays them
in a drop-down list, rather than requiring the user to iteratively
guess the port number. (#625)
[Enhancement] This release features a complete rewrite of the
Meyer Data Acquisition input and output port configuration screens.
This makes the screens much better organized, and should make them much
easier to understand. (#625)
[Enhancement] Timed popups (alert
windows that appear, then disappear after a set amount of time if the
user ignores them—useful for non-critical alerts, e.g., “reached the end of the input file”) now support the Ctrl+C keyboard shortcut for , to make it easier to search
for the popup contents online and/or mail it to tech support.
(#2599)
[Fix] Fixed an integer overflow in the “Specify how often to check for data”/“Specify how often to send
a line of data” text file polling options.
Previous versions of Meyer Data Acquisition could not use any polling
interval longer than ~33 seconds. Meyer 2012 allows polling
intervals up to 1 week, which matches the original design.
(#2583)
[Fix] Long pathnames could be truncated on the screen. This screen now
dynamically adjusts its size to accommodate the current output
pathname. (#2518)
[Fix] Overwriting a large output file (e.g., several hundred
thousand lines) could cause Meyer Data Acquisition to appear to stop
responding while it counted the exact number of lines in the file so
it could show an exact line count in the screen. This line counting
process now runs in the background after the screen is already open.
(#2555)
[Fix] The horizontal scroll bar was missing from the Meyer Data
Acquisition data preview panel. (#2500)
[Fix] The Meyer Data Acquisition now allows commas in the “Name” field. (#2580)
[Fix] Timed popups (see #2599) could appear on the wrong
monitor in multi-monitor setups. Specifically, if the user had ever
moved one of these popups to a secondary monitor, all future popups
would appear on that monitor regardless of the placement of Meyer Data
Acquisition. (#2518)
-
[Fix] When saving to an output file on a network drive across a
wide-area network link, if the WAN connection dropped then Meyer Data
Acquisition would stop saving to the output file due to an I/O error.
However, the visual cues indicating that this had happened were very
subtle and easy to miss, so it was possible to lose data in this
situation. (#2481, #2518)
Meyer Data Acquisition now halts and clearly signals an error in
this case.
(Meyer & Associates, Inc. does not
recommend saving the Meyer Data Acquisition output file to a network
drive located across a WAN link.)
The same conditions could technically have occurred while saving
the output file to a LAN network drive, but this was much less likely
due to the more reliable nature of local area networks.
