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

• [Enhancement] MFast no longer closes its plots when the units change. (#1666)

• [Fix] The group boxes on the MFast calculations screen were not being shown until the user pressed the Alt key. (#2027)

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:

  1. Propped Payzone Height,
  2. Fracture Permeability,
  3. Fracture Width, and
  4. 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:

  1. Designs based on maximum fracture length, total slurry volume, or total proppant mass.
  2. Non-linear proppant ramping.
  3. 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.
  4. Automatic treatment schedule and NPV designs for tip screen-outs and frac packs.
  5. Wellbore hydraulics solution.

• [Enhancement] Multiple enhancements to the Three Dimensional plots. (#2008, #2042, #2043)

  1. Any text containing non-English characters would not appear in the VRML viewer.
  2. Backslashes were not being escaped properly.
  3. The plot axes are now thinner.
  4. 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:

  1. The red pointer bar can now be adjusted in either direction when its lower edge is very near its upper edge.
  2. 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)

  1. The ability to add or remove multiple parameters at once.
  2. The ability to rearrange parameters after they are selected.
  3. Enhanced error checking.
  4. Merge Data Sets now computes and displays the minimum and maximum time step. Also, fixed an error in computing the merge time step.
  5. 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)

Meyer Data Acquisition

• [Fix] Don’t display the “reached the end of the input file” message until all modal screens are closed. (#1960)

All Apps

• [Fix] Fixed a bug which prevented the user from overwriting offline files. (#2061)

• [Fix] Prevent multiple radio buttons in the same group from being selected within the Plot Configuration | Layout screen. (#2128)

Units

• [Fix] Several screens were displaying proppant permeability in Permeability units, not Proppant Permeability units:

  • MFrac: The Proppant Design Summary table on the report;
  • MProd: The Fracture Permeability column in the NPV/Multi-Case Fracture Characteristics and Variable Fracture Conductivity screens, and their corresponding tables on the report;
  • Non-Darcy Database: The Non-Darcy Database Code Preview screen (for setting up the preview plot).

  (#2063, #2081, #2082)

MFrac

• [Enhancement] Auto-scale and group the Graphical Treatment Schedule’s Y axis curves according to volume, rate, and concentration. (#2075, #2077)

• [Fix] Disable and adjust columns in the Real-Time Treatment Schedule while MFrac receives real-time data from MView. (#2073)

• [Fix] Fixed a glitch drawing the zoom rectangle in the Graphical Treatment Schedule while receiving real-time data. (#2069)

• [Fix] Fixed a glitch where more than one stage could appear to be selected in the Graphical Treatment Schedule. (#2074)

• [Fix] Fixed dragging the restart time back (in the Graphical Treatment Schedule) when the restart time is past the end of real-time data. (#2024) Also fixed dragging the right-hand side of the stage with the current end of real-time data. (#2065)

• [Fix] Paste and Fill Down now work in the Treatment Schedule’s variable column. (#2054)

• [Fix] The cursor no longer flickers when reading real-time data in the Treatment Schedule.

• [Fix] The MFrac Real-Time | Add Log Entry command now works correctly. This command had been non-functional since Meyer 2005. (#2094)

• [Fix] The Wellbore Hydraulics Deviation Tab now defaults to “Calculate TVD,” not “Calculate Angle,” on File | New. (#2079)

MPwri

• [Fix] Modified Stress now plots correctly even when the output units for Stress, Stress Gradient, and Height are inconsistent. (#2056)

MWell

• [Fix] Removed bogus check for “number of multiple parallel fractures” on the Zones screen. This variable doesn’t exist in MWell. (#2058)

• [Fix] The Fracture Pressure Table (under Zones) now defaults to “ignore table” on File | New. (#2079)

MinFrac

• [Enhancement] Added more checkpoints for improved recovery of MinFrac documents after a crash. (#2090)

• [Fix] Fixed a crash in Output | View Report when some previously valid time scales become invalid (i.e., when they are missing data). (#2093)

• [Fix] Modified numerical calculation of derivatives for oscillating pressures to obtain a better general curve fit of the data. This improves the results when the data range contains large pressure changes in the water hammer region. (#2078)

• [Fix] Nolte G time log scales were broken on Regression plots when time units were set to days or years. (#2132)

• [Fix] The Horner plot pore pressure gradient calculation was incorrect for bottom hole analyses. (#2119)

• [Fix] The ISIP could not be moved when zoomed in on a Regression plot with “Volume and Rate” or “Time and Rate” selected on Data | Options | Graphical under “User Specified Pumping Data.” (#2071)

• [Fix] The red pointer bar always stays within the visible area of the plot. (#2068)

MView

• [Fix] Fixed a crash in the MView Real-Time | Add Log Entry command with over 102 channels of Real-Time data defined in Data Sets | Setup. (#2096)

• [Fix] Fixed data corruption when using the Edit Data command to edit the Real-Time data set. (#2092)
