Meyer 2008 (Released 2008-03-19)
| From: |
Bruce R. Meyer, Meyer &
Associates, Inc. |
| To: |
Meyer Hydraulic Fracturing Software Users |
| Subject: |
Meyer 2008 Software Suite version 5.40 |
| Date: |
March 2008 (latest release dated
October 2008) |
Dear Users:
We are pleased to announce the release of the Meyer 2008 suite
of software version 5.40 dated March 2008.
Please note that the Meyer 2008 system requirements have
changed. Microsoft operating systems before Windows 2000 are no
longer supported.
Meyer 2008 represents over two years worth of new features,
enhancements, and bug fixes. Here are just a few of the highlights.
(You can find much more detail in the section
“Meyer 2008 Changes,” below.)
MProd
-
Non-Darcy Flow. MProd now
has the ability to model non-Darcy flow in the fracture. This
allows the user to determine the effect of non-Darcy flow on
productivity.
-
Non-Darcy Database. MProd and
MFrac now have access to a database of non-Darcy correlations.
The system database contains several well-known correlations, where
each correlation can be plotted in the form of Beta (β) versus
Permeability (k), or as Porosity (ϕ) versus Permeability (k).
The database can also plot multiple correlations at once, making it
easy for the user to compare them.
-
Simultaneous Case Comparisons.
MProd can now compare non-Darcy fracture, Darcy fracture, base and
stimulated cases simultaneously in the reports and plots. Various
comparative options, including numerous new plots, are
available.
-
Proppant Calculator. This handy
accessory makes it easy to see the interaction between various
numerical proppant properties. The user selects a beta (β)
correlation and enters proppant property data. The Calculator uses
this to compute fracture permeability (k) and a beta
factor (β).
MFrac
-
Automatic Treatment Design
enhancements including:
- Designs based on maximum fracture length, total slurry
volume, or total proppant mass.
- Non-linear proppant ramping.
- Multi-stage rate step downs for frac packs. This option
directs the simulator to schedule the pumps to shut down
gradually over several stages, rather than all at once,
at the end of a job.
- Automatic treatment schedule and NPV designs for tip
screen-outs and frac packs.
- Wellbore hydraulics solution.
-
Plot Versus Measured Depth. All
MFrac plots with depth scales now have the ability to use measured
depth for the scale. This is very useful for working with
deviated wellbores.
-
Fluid Loss Log File Importing.
We have enhanced the Log File Importing module by adding the
ability to import Fluid Loss properties from log files. This is
similar to the Rock Properties import feature we added in
Meyer 2006.
-
Updated Proppant Databases.
Atlas Resin Proppants has provided us with new entries for our
system proppant databases.
To ensure that you are using the latest proppant data from the
System Proppant Databases, copy the currently used proppant types
from the System Database to the User Database. If you are importing
files with older proppant data and have a proppant code conflict,
click Cancel (i.e., to make sure that the latest System Proppant
Database values that were copied into the User Database are being
used).
MView
-
Build Unlimited Plots. MView is
no longer limited to six plots; it is possible to build an
arbitrary number of them.
-
Merge Data Sets. This release
of MView features a major overhaul of the Merge Data Sets
feature. Enhancements include:
- The ability to add or remove multiple parameters at once.
- The ability to rearrange parameters after they are
selected.
- Enhanced error checking.
- Merge Data Sets now computes and displays the minimum and
maximum time step. Also, fixed an error in computing the merge
time step.
- The default text for numbers that cannot be interpolated is
now specified directly in Merge Data Sets instead of being buried
under Preferences.
Documentation
All Apps
-
Simulation Data Windows. All
applications with simulators now feature modular, configurable
Simulation Data Windows. These windows are a vast improvement over
the windows of the same name in previous editions of the Meyer
Software.
- The columns in these windows can now be individually
hidden and shown, and reordered by drag-and-drop.
- There are more channels of data available for display, and
additional windows, such as an NPV window in MFrac.
- The windows are easier to organize and less obtrusive when
the user has plots open. In previous releases, if the user ran
the simulator with plots open, the Simulation Data Windows would
pop up over the plots. Now they open in the background.
-
Document Management. This
release features a complete overhaul of the code for opening and
saving files. The code is now much more reliable at handling
corrupt or old files. As a side effect of these changes, the
apps are now much more precise about determining whether the input
data has changed, and whether files need to be saved. Additionally
this work has allowed us to fix several long-standing bugs in the
plots.
-
Error Checking. We have added
an Ignore All button to all of our
input screens. This makes navigating the screens much more
efficient because the user can now defer error checking until the
whole case is entered.
-
Reports. The flagship
improvement here is the Print Preview
feature which we have added to all of our reports. It is now
possible to print a single page, or a range of pages, in addition
to printing the whole report. We have also improved the HTML
export feature and the code for handling images on the report.
-
Spreadsheet Configuration. The
spreadsheets now support more usability features such as a
user-specified color for alternating and frozen rows, and an option
to display an ellipsis if cell contents are truncated.
-
Operating Systems.
Meyer 2008 runs on Windows Vista,
Windows Server 2003, Windows XP, and
Windows 2000.
In addition to the highlights listed here, Meyer 2008 features
over 200 additional bug fixes and enhancements and numerous
internal quality improvements to the installer, the reports, the
spreadsheets, and the document management code. The amount of work put
into this release lays the foundation for years’ worth of future
enhancements.
Please do not hesitate to contact me with any questions.
Sincerely,
Bruce R. Meyer, Ph.D., P.E.

All Apps
-
[Enhancement] Added an Ignore All
button to error checking in all of our input screens. This makes
navigating the screens much more efficient because the user can now
defer error checking until the whole case is entered. (#672,
#844)
-
[Enhancement] Added many additional units to the applications.
(#1915, #2003, #2022)
-
[Enhancement] Clarified software license key messages, e.g.,
for a missing or invalid license key. (#1967)
-
[Enhancement] Document Management.
This release features a complete overhaul of the code for opening
and saving files. The code is now much more reliable at handling
corrupt or old files. As a side effect of these changes, the
apps are now much more precise about determining whether the input
data has changed, and whether files need to be saved. Additionally
this work has allowed us to fix several long-standing bugs in the
plots.
-
[Enhancement] Meyer 2008 is Windows Vista compatible. (#1887, #1894)
-
[Enhancement] Updated all user interfaces to use Windows XP
and Vista visual styles.
-
[Fix] Ensure that the apps always start in the foreground.
-
[Fix] Fixed a crash when creating PDF (using the Adobe PDF
printer driver) from a plot embedded in an input screen, and
clicking Cancel on “Select PDF Filename.” Only embedded plots were
affected: for example, the plot shown by the “Plot” button on Rock
Properties. (#2044)
-
[Fix] Fixed problems with permeability units: increased maximum
limit, renamed 10−6 m2 to
(10−6 m)2, and corrected the
conversion factor for mm2. (#2028)
All Apps With Simulators
-
[Enhancement] Added a new Tools |
Proppant Calculator accessory to MFrac and MProd.
The Proppant Calculator makes it easy to see the interaction
between various numerical proppant properties. The user selects a
beta (β) correlation and enters proppant property data. The
Calculator uses this to compute fracture permeability (k) and a
beta factor (β).
The Tools menu, which first
appeared in Meyer 2006, is a place for useful graphical tools
that aren’t part of the applications’ main workflow, and for
options that apply to the applications as a whole rather than any
individual document or simulator. Watch this space for exciting
future developments.
-
[Enhancement] Added a (Running) indicator to the title bar, to
show at a glance whether the simulator is running. (#1847)
-
[Enhancement] All applications with simulators now feature
modular, configurable Simulation Data
Windows. These windows are a vast improvement over the
windows of the same name in previous editions of the Meyer
Software. (#1248, #1764, #1866)
- The columns in these windows can now be individually
hidden and shown, and reordered by drag-and-drop.
- There are more channels of data available for display, and
additional windows, such as an NPV window in MFrac.
- The windows are easier to organize and less obtrusive when
the user has plots open. In previous releases, if the user ran
the simulator with plots open, the Simulation Data Windows would
pop up over the plots. Now they open in the background.
The windows are broken into components to match the structure of
the simulators’ output. In previous releases, the windows were
monolithic.
-
[Enhancement] Error check the template file for the “show
template before running simulation” run option. (#1858)
-
[Enhancement] Improved the accuracy of the flags that determine
whether output data is stale (i.e., need to re-run the simulator),
and whether the document needs to be saved. (#1704, #1785)
-
[Enhancement] It is now possible to close the applications while
the simulator is running. Clicking the close box, or hitting
Alt+F4, initiates a graceful shutdown of the simulator and the
application. (#1786)
-
[Enhancement] Stopping the simulator now works consistently
across all applications. (#1812)
-
[Fix] Keep the template description in the Run Options screen
up-to-date when saving over an existing template. (#1948)
Databases
-
[Enhancement] Added a new non-Darcy
database.
MProd and MFrac now have access to a database of non-Darcy
correlations. The system database contains several well-known
correlations, where each correlation can be plotted in the form of
Beta (β) versus Permeability (k), or as Porosity (ϕ)
versus Permeability (k). The database can also plot multiple
correlations at once, making it easy for the user to compare
them.
-
[Enhancement] Atlas Resin Proppants has provided us with new
entries for our system proppant databases.
To ensure that you are using the latest proppant data from the
System Proppant Databases, copy the currently used proppant types
from the System Database to the User Database. If you are importing
files with older proppant data and have a proppant code conflict,
click Cancel (i.e., to make sure that the latest System Proppant
Database values that were copied into the User Database are being
used).
-
[Enhancement] Fluid, proppant, and acid databases now support
codes up to seven characters long. The new non-Darcy database also
supports seven character codes. (#1869)
-
[Fix] Fixed sort order in the user database screen when
inserting a new item from a system database. (#1819)
Documentation
-
[Enhancement] Updated the Meyer User’s Guide to include help for
the new features of Meyer 2008.
-
[Enhancement] The Russian Meyer User’s
Guide is now up-to-date. The Guide is available as a PDF,
and it also forms the basis for the Russian Meyer 2008 HTML
help system. (#1500)
Installer
-
[Enhancement] The installer now verifies checksums during Repair
Mode. This allows us to detect and repair corrupted files,
specifically, application executables corrupted by viruses.
(#1899)
-
[Fix] Ejecting the CD with the CD browser running could lead to
a crash. (#1932)
Plots
-
[Enhancement] Added a keyboard shortcut for copying the plots to
the clipboard. (#1721)
-
[Enhancement] Added a plot legend orientation configuration
option with separate position settings to allow the plot legend to
be always shown across the top of the plot. Also, added a
configuration option to control the displaying of units on the
plot legend. (#595)
-
[Enhancement] Added a Plot |
Show/Hide Information Box command to the plot menu, to
give the user better control of plot information boxes (i.e.,
programmatically controlled text blocks). (#1924)
-
[Enhancement] Improved context sensitivity in the plot menus.
Plots are now enabled if either the current input options, or the
input options from the latest run, indicate that they are relevant.
This makes it possible to open all relevant plots before starting
the simulator, even if the input options have changed. (#965)
-
[Enhancement] The “Default” option in the plot layout
configuration is now a checkbox, not a radio button. This allows
the user to toggle “Default” without losing their non-default
configuration. (#1942)
-
[Fix] Fixed a bug drawing shaded contour plots when there are no
scale levels (e.g., when there is no data to display). (#1929)
-
[Fix] Fixed a bug in the plot configuration, where the
settings on the General | Colors tab could overwrite the
settings for Contours | Filled Area Colors. This was
especially noticeable for the Pump Time and Shut-In Time areas in
MinFrac. (#2047)
-
[Fix] Fixed a double gridline that could appear in plots with
both left and right scales active. (#1670)
-
[Fix] Fixed enabling and disabling of user interface elements on
the plot legend configuration screen when the user changes
a setting on the plot layout configuration screen.
(#1867, #1868)
-
[Fix] Keep font settings synchronized between the various panes
of a multi-pane plot. (#1966)
-
[Fix] In Meyer 2006 and earlier, the plot scales sometimes
appeared to have repeated numbers (e.g., -1 0 1 1 2). This was due
to the scale drawing code rounding the numbers to the point where
they were indistinguishable. In the previous example, “1 1”
may have actually represented “1.0 1.5.” (#1978)
-
[Fix] Show the default colors when resetting the plot colors
with “Use Defaults.” (#1943)
-
[Fix] The legend font size in Default Plot Attributes now
persists between sessions. (#1941)
-
[Fix] The 20th through 30th templates listed under Plot |
Templates did not work. (#1707)
Reports
-
[Enhancement] Added Print Preview
to all reports. It is now possible to print a single page, or a
range of pages, in addition to printing the whole
report. (#1753)
-
[Enhancement] Reports now have a right click context menu
featuring Print Preview, Print, Export, and Configuration.
(#2005)
-
[Enhancement] The alternate image for HTML export now works even
if “image at top of report” is not selected. (#218)
-
[Fix] HTML export now works with image filenames containing
characters with a special meaning in HTML, e.g.,
ampersands (&). (#1760)
-
[Fix] Printing with too large a large font size could crash by
printing empty pages until the printer was out of paper.
(#2018)
-
[Fix] Fixed fonts in RTF export. (#1784)
-
[Fix] The alternate image for HTML export now works in any web
browser, not just Internet Explorer. (#1789)
-
[Fix] The image at the top of the report now prints with the
correct aspect ratio. (#1765)
Spreadsheets
-
[Enhancement] Added multiple new spreadsheet options, accessible
via Tools | Options. In particular, it is now possible to
define an alternate background color
for the spreadsheets, to improve visibility on spreadsheets with
many rows. (#1754, #1875, #1877, #1883)
-
[Enhancement] Added new shortcut keys to insert (Ctrl+Plus)
and delete (Ctrl+Minus) rows. (#1896)
-
[Enhancement] Spreadsheets now have a right click context menu
featuring Cut, Copy, and Paste. (#1745)
-
[Fix] Exporting or importing a spreadsheet caused the
applications to crash if the file in question was locked by a third
party application. (#1953)
-
[Fix] Fixed multiple user interface consistency issues with
enabled and disabled cells. (#1787, #1793)
-
[Fix] Unfreezing rows in certain spreadsheets could cause
extraneous rows (which were supposed to be hidden) to appear.
(#1744, #1801)
MFast
MFrac
-
[Enhancement] Added non-Darcy
effects to the Proppant Criteria screen.
-
[Enhancement] Added the ability to plot
contours versus Measured Depth. This is useful for
correlating plots with well logs, especially for deviated wells.
(#1156)
-
[Enhancement] Added the ability to import
Fluid Loss properties from log files. This is
similar to the Rock Properties import feature we added in
Meyer 2006. (#1593)
-
[Enhancement] Added the following fields to the report for
Automated NPV Design cases:
- Propped Payzone Height,
- Fracture Permeability,
- Fracture Width, and
- Beta.
-
[Enhancement] Added “Zone Name” to the “Total Fluid Leakoff
Coefficient (EOJ)” table in the report. (#2041)
-
[Enhancement] Increased the number of real-time data points that
can be received from MView without compression from 15,000
to 86,400. (#1913)
-
[Enhancement] Issue a warning when the VRML pathname (for 3D
plots) contains a # character. This character causes
problems for Internet Explorer VRML viewer plug-ins. (#1980)
-
[Enhancement] Linear interpolation is now optional in the Rock
Properties Log File Importing (MLog) module. In Meyer 2006
linear interpolation was always enabled. (#1720)
-
[Enhancement] MFrac can now back calculate treatment schedule
values from the stage and total mass columns. (#1950)
-
[Enhancement] Multiple enhancements to Auto Design (#1730, #1742) including:
- Designs based on maximum fracture length, total slurry
volume, or total proppant mass.
- Non-linear proppant ramping.
- Multi-stage rate step downs for frac packs. This option
directs the simulator to schedule the pumps to shut down
gradually over several stages, rather than all at once,
at the end of a job.
- Automatic treatment schedule and NPV designs for tip
screen-outs and frac packs.
- Wellbore hydraulics solution.
-
[Enhancement] Multiple enhancements to the Three Dimensional
plots. (#2008, #2042, #2043)
- Any text containing non-English characters would not appear
in the VRML viewer.
- Backslashes were not being escaped properly.
- The plot axes are now thinner.
- If Three Dimensional output failed because MFrac was unable
to open an output file, subsequent changes to the input data
could be lost. This was also true for 3D export to Exodus.
-
[Enhancement] Added fluid volumes and proppant masses,
respectively, to the list of fluids and proppants in the report.
(#1951)
-
[Enhancement] Support horizontal and other extremely deviated
wellbores in the Log File Importing (MLog) module by allowing the
selection of an MD interval for each TVD interval. (#1848)
-
[Enhancement] The Fluid Loss screen now has a Plot button. (#1940)
-
[Enhancement] The Fluid Loss screen now has a Pressure Gradient channel. (#1926)
-
[Enhancement] The Log File Importing module, MLog, can now
handle LAS files that use line wrapping, and LAS files with column
headers on a section title line. (#1795, #2035)
-
[Enhancement] The Treatment Schedule no longer becomes
unresponsive when MView is sending an extremely fast data stream.
(#1969)
-
[Fix] Added units to Average Carbonate Porosity and Fraction of
Non-Reactive Fines in the Acid Data screen. (#234)
-
[Fix] Certain treatment plots could not be stored in plot
templates—storing them would corrupt the templates.
(#1706)
-
[Fix] Deleting or pasting pay zone data using the spreadsheet on
the Zones screen did not always work. (#2010)
-
[Fix] Draw the frac pack screen (in Wellbore Hydraulics)
correctly when the units are set to metric. (#1937)
-
[Fix] Error checking in the Perf Zones screen can now open the
Pay Zones screen if the Pay Zones data contains an error.
(#2034)
-
[Fix] Extremely old (Meyer 1999 and earlier) MFrac
documents with a corrupt treatment schedule could cause MFrac to
crash and require manual intervention (i.e., a tech support call)
to get it working again. (#1829)
-
[Fix] Fixed a crash hitting Ctrl+N (File | New) or Ctrl+O
(File | Open) while running the simulator. (#1803)
-
[Fix] Fixed a crash inserting a row in the last row of the Zones
screen. (#1813)
-
[Fix] Fixed a crash running
fluid-type dependent leakoff with less than three fluid loss layers
defined. (#2135)
-
[Fix] Fixed a crash when switching from proppant to acid with
the Graphical Treatment Schedule open. (#1834)
-
[Fix] Fixed a long-standing intermittent crash when starting
MView and MFrac at the same time. (#1351)
-
[Fix] Fixed a problem in the Log File Importing (MLog) module,
where min/max depth values could be loaded as row numbers.
(#1736)
-
[Fix] Fixed a problem in the Real-Time Treatment Schedule
screen, where the first stage time could keep increasing as
MFrac received real-time points from MView. This did not affect
the simulation, only the Treatment Schedule and Graphical Treatment
Schedule screens. (#2045)
-
[Fix] Fixed an off-by-one error tracking stages in delta
pressure across the perfs. (#1822)
-
[Fix] Fixed auto-scaling of the X axis in stress plots in
MFrac. (#1979)
-
[Fix] Fixed computation of the Coiled Tubing reel volume.
(#1802)
-
[Fix] Fixed error checking after pasting identical rows into the
Zones screen. (#2025)
-
[Fix] Fixed jagged appearance of the Acid Contour plots. This
was broken in Meyer 2006. (#1728)
-
[Fix] Fixed oscillations in the simulator output for a very
unusual case with a high stress layer in the middle of two lower
stress layers, perforated across the whole interval, and fracture
initiation interval set to “perforated interval.” (#1763)
-
[Fix] Fixed the error message and liquid volume calculation in
the Treatment Schedule when real-time proppant concentration data
from MView is greater than the maximum allowable concentration.
(#2026)
-
[Fix] Fixed units for Dimensionless Fracture Conductivity on the
report, under Summary of Etched Characteristics. (This only affects
acid cases.) (#1876)
-
[Fix] For cases with multiple
parallel fractures, the fracture volumes and proppant mass shown in
the treatment plots during shut-in were incorrect.
(#2139)
-
[Fix] MFrac did not always properly flush the last-run input
data to disk. This could potentially have corrupted the last-run
input data. (#1701)
-
[Fix] MFrac now responds to user input while flashing the
taskbar icon after the simulation finishes. (#1844)
-
[Fix] Save critical stress values to disk in the Log File
Importing (MLog) module. This fixes a problem with critical
stresses on the Property Generation and Zones pages. (#1734)
-
[Fix] Show the proppant code and description in the report when
proppant transport is off. (#1886)
-
[Fix] The Fluid Loss screen nominally supported 1,000 rows, but
only 900 were stored correctly. (#1930)
MPwri
-
[Enhancement] Enhanced computation of fluid loss per unit area
in the wellbore, and the average in each layer. Rather than
assuming a large fluid loss (i.e., fracture efficiency goes to
zero) as in most waterflood applications, the code now uses a
general integral formulation. (#1740)
-
[Fix] Error check Cake Properties before running the simulator.
Previous releases were missing this error check. (#2021)
MWell
-
[Fix] Fixed error checking when running the simulator after
converting an acid case from MFrac. (#1761)
-
[Fix] The Net Pressure diagnostic plots were not using the
restart time, and they were calculating the Nolte slope
incorrectly. (#1968)
MinFrac
-
[Enhancement] Added a new Nolte - FL2 plot to the
After Closure Analysis module in the Analysis Wizard. (#2004)
-
[Enhancement] Added stress gradient, extension gradient, and
pore gradient to the report and to the information boxes on the
plots. (#1927)
-
[Enhancement] Allow report configuration changes to apply to the
Analysis Wizard without opening and closing the wizard. (#1773)
-
[Enhancement] Enable the Simulation Using Base Data screen, and
the corresponding section in the report, in User Specified Closure
mode. (#2040)
-
[Enhancement] Increased the number of real-time data points that
can be received from MView without compression from 15,000
to 86,400. Also increased the maximum number of points that
can be imported from a file from 16,382 to 86,400.
(#1913)
-
[Enhancement] It is now possible to enter Rate and Pressure
points on the DP Fric and DP Frac tables for the Step
Down and Step Rate analyses in MinFrac. (#2039)
-
[Enhancement] More drop-down list boxes now remember their
selected time scales. (#1729)
-
[Enhancement] Separate configuration storage for the Regression
plots, to make it easier to see each plot in a different time
scale. (#1970)
-
[Fix] Add Net Pressure to the Selected Points section in the
report even when no regression was performed, i.e., when
lines 1 and 2 are not present. (#1723)
-
[Fix] Fixed a bug opening some old .m20 files. For example,
Meyer 2006 could not open the MinFrac sample files from
Meyer 2001. (#1920)
-
[Fix] Fixed a crash and inconsistent behavior when clicking
Units with a report open in the Analysis Wizard. (#1776)
-
[Fix] Fixed a crash in the plots when deleting a
programmatically controlled text block. Additionally, this type of
text block now remembers when the user hides it, and stays hidden.
(#1921, #1931)
-
[Fix] Fixed data compression when receiving real-time data from
MView and MView is reset. (#1912)
-
[Fix] Fixed handling of the delete key for plot text blocks in
the Analysis Wizard. (#1923)
-
[Fix] The red pointer bar at the top of the plots can
now extend all the way to the beginning and end of the data for all
X scales. (#1925, #1972)
Furthermore:
- The red pointer bar can now be adjusted in either direction
when its lower edge is very near its upper edge.
- The red pointer bar, and any points, are now adjustable even
if they lie on the very edge of the plot.
-
[Fix] The “User Specified (TC)” checkbox is now disabled in
After Closure Analysis if there are no points. (#1800)
MProd
-
[Enhancement] MProd now has the ability to model non-Darcy
flow in the fracture. This allows the user to determine the effect
of non-Darcy flow on productivity.
-
[Enhancement] MProd can now compare non-Darcy fracture, Darcy
fracture, base and stimulated cases simultaneously in the reports
and plots. Various comparative options, including numerous new
plots, are available.
-
[Enhancement] Added the ability to import
Variable Fracture Conductivity data from MFrac.
Specifically, MProd can now import fracture permeability, propped
width, height, conductivity, and beta factor as a function of
position in the propped fracture.
-
[Enhancement] Added the equivalent
fracture skin for a finite conductivity fracture to the
report. (#1993)
-
[Enhancement] Check that the Time column in the Production Data
screen is increasing. Previously the simulator threw out invalid
data without warning the user. (#1712)
-
[Enhancement] Improved the accuracy of the tri-linear
solution. (#1749)
The original tri-linear solution assumed flow could only enter
the wellbore through the fracture. Although the previous release
did account for flow through the wellbore, Meyer 2008
implements an enhancement for low conductivity fractures using the
resistivity methodology formulated in SPE 95941.
Consequently, as the fracture conductivity goes to zero the
composite solution now asymptotes to the radial solution with an
initial pre-frac skin.
The solution now also accounts for fracture damage (skin).
-
[Enhancement] MProd now has the ability to work with various
beta (β) correlations via the new non-Darcy database.
-
[Enhancement] Sped up the History Match simulator for closed
formations. (#1752)
-
[Enhancement] The Production (single-case) and History Match
simulators can now save their output if the user clicks Stop before
the simulation completes. (#1884)
-
[Enhancement] The Wellbore Skin Factor (base) and the Wellbore
Skin Factor (prefrac) are now stored separately. In
Meyer 2006 these fields were stored in the same location,
which led to improper error checking. (#1716)
-
[Enhancement] When running with the fracture data source set to
an MFrac document, we now show the document’s pathname on the
report. (#1878)
-
[Fix] Fixed an infinite loop in the Design Optimization
simulator when upgrading an old Production case, switching to
Design Optimization without filling in the fracture skin, and then
running the simulator. (#1782, #1804, #1831)
-
[Fix] Fixed an infinite loop in the History Match simulator with
min/max error checking disabled and with a rate, concentration, or
permeability very close to zero. (#1885)
-
[Fix] Fixed an infinite loop in the History Match
simulator when all of the following were true: unfractured closed
system, fluid type set to oil or water, internal PVT table off,
production boundary condition set to rate, and one (but not both!)
of minimum or maximum dimensionless reservoir aspect ratio set to
zero. (#1907)
-
[Fix] Fixed clearing output data when opening a new
document.
-
[Fix] Fixed data corruption when entering more than
100 years on the Production Data screen. (#1774)
-
[Fix] Fixed multiple bugs in MProd where the input data could
change silently due to validation code running in a different
screen. (#1958)
-
[Fix] Fixed running with a fracture length greater than the
reservoir dimensions. (#1771)
-
[Fix] Fracture skin is now implemented correctly for a closed
system produced at a constant bottomhole flowing pressure. This
change affects the Production and History Match simulators.
(#1746)
-
[Fix] When exiting the Formation screen, recalculate the
dimensionless conductivity on the Propped Fracture Characteristics
screen. (#1747)
-
[Fix] Reduced prompting to run the simulator. This was broken in
Meyer 2006 (i.e., MProd did not stop prompting even if the
user clicked Continue.) (#1837)
-
[Fix] Show oil compressibility and viscosity in the Formation
Data section of the report for oil cases with the internal PVT
table enabled. (#1908, #1909)
MNpv
-
[Enhancement] The MNpv options screen now has Change and Ignore
buttons. (#556)
-
[Enhancement] Show the pathname of the MProd document used as an
NPV/multi-case data source on the report. (#1879)
-
[Fix] Certain plots would crash if opened with no output data
(e.g., by a plot template). (#1965)
-
[Fix] Fixed the Cancel button on the Units screen when the
currency symbol has changed. (#1211)
-
[Fix] Fracture DROI versus Propped Length plots were showing the
wrong data. The average unit revenue array was being improperly
populated, because the code was using the wrong index. (#1748)
-
[Fix] Show the Unit Cost selection on the report. (#1879)
MView
-
[Enhancement] Added a splitter bar to the Build Plots screen.
(#1947)
-
[Enhancement] Increased the number of real-time data points that
can be stored without compression from 15,000 to 86,400.
(#1913)
-
[Enhancement] Major overhaul of
Merge Data Sets. (#363, #1935, #1936)
- The ability to add or remove multiple parameters at once.
- The ability to rearrange parameters after they are
selected.
- Enhanced error checking.
- Merge Data Sets now computes and displays the minimum and
maximum time step. Also, fixed an error in computing the merge
time step.
- The default text for numbers that cannot be interpolated is
now specified directly in Merge Data Sets instead of being buried
under Preferences.
-
[Enhancement] Min and max filter values are no longer
permitted to be equal within the Data Set Setup screens. (#2049)
-
[Enhancement] MView now shows all available file types for
importing in the drop down list box for choosing a file for Data
Sets | Setup. Specifically, it is now much more obvious that
MView can import MFrac output data into Data Sets | Setup.
(#1989)
-
[Enhancement] Removed the six plot maximum from Build Plots.
MView can now build any number of
plots. (#1881)
-
[Fix] CO2 and N2 bottomhole quality units
were wrong when importing MFrac output data into MView. (#1865)
-
[Fix] MView no longer loses the start, stop, and step values in
Data Sets | Setup when switching from Real-Time to Replay.
(#1726)
-
[Fix] Real-time shift values could become corrupt when
re-entering Data Sets | Setup, for certain choices of units.
(#1872)
-
[Fix] Restored the ability to show multiple parameters on one
axis before any data arrives. This was broken in Meyer 2006.
(#1719)
-
[Fix] The Edit Shifts dialog now works correctly for Real-Time
data sets. (#2032)
-
[Fix] The Insert and Delete Row buttons now work properly in the
Parameters screen. This was broken in Meyer 2006. (#856)
