Date:	June 2006 (latest release dated March 2007)

Dear Users:

We are pleased to announce the release of the Meyer 2006 suite of software!

The Meyer 2006 software, released 2006-06-27, represents almost 18 months of new features, enhancements, and bug fixes. Here are some of the highlights. (You can find a complete list in the section “Meyer 2006 Changes,” below.)

MFrac

• Log File Importing. We have developed an improved Log File Importing module for mechanical rock properties. This new module allows for importing, generating, and calculating mechanical rock properties from a number of different input data sources (LAS, Gamma Ray, etc).

• Proppant Distribution Style. We have added a new “Proppant Distribution Style” option to the Auto Design Treatment Schedule. This option enables auto design of the treatment schedule based on a maximum proppant concentration, a target concentration per unit area, or a target dimensionless fracture conductivity.

• Pressure Dependent Leakoff. We have added a new “Pressure Dependent Leakoff” table to enable modeling fluid loss as a function of pressure. This is helpful in simulating leakoff in naturally fractured reservoirs that exhibit pressure dependent fluid loss.

• Updated Proppant Databases. Atlas Resin Proppants, Hexion Specialty Chemicals, and Saint-Gobain Corporation have provided us with new 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).

MProd

• History Match Simulation Option. MProd now has an option to history match measured production data with simulated data. This option provides the user with an objective methodology for determining unknown or uncertain parameters (through regression). The procedure is implemented by parametric optimization to minimize the error (standard deviation) between the measured and history matched results.

• Fracture Design Optimization. Fracture Design Optimization enables the user to find the optimum (i.e., maximum production) fracture design (length, width, conductivity) for a given mass of proppant injected.

• Pseudosteady-State Analysis Solution. An advanced pseudosteady-state solution for a well with a finite conductivity vertical fracture has been implemented based on the reservoir/fracture domain resistivity concept formulated by Meyer (2005) in SPE 95941.

Meyer 2006 requires Windows Server 2003, Windows XP, Windows 2000, Windows 98 Second Edition, Windows Me, or Windows NT 4.0 SP6a with Internet Explorer 5.01 or greater. The minimum system requirements are listed in Table 1.1 of the User’s Guide. See the Meyer Fracturing Software User’s Guide Section 1.3 for additional instructions on installing the Meyer Software.

If you have any questions regarding the Meyer 2006 upgrade please feel free to contact me.

• [Fix] Multiple improvements to text blocks (#590):

  1. Text blocks now resize and print without re-wrapping the text block contents.
  2. New lines may be added via the Enter key.
  3. The Escape key no longer acts as an Undo command; instead, it ends editing, keeping changes.

• [Fix] Prompt before deleting a plot text block. (#1505)

Bar Charts

• [Fix] Do not draw outside the plot area, and make zooming consistent with the other plots. (#1366)

Reports

• [Enhancement] Do not truncate data during text file export. (#1570)

• [Enhancement] Improved Export Report error handling. If exporting a report fails, don’t try to open the target file, since this produces confusing results when, for example, the target file is a read-only earlier version of the report. (#989)

• [Enhancement] Modernized HTML export. Reports now export as valid HTML 4.01 Transitional. (#427)

• [Fix] Escape control characters in RTF export. Previously, RTF export could produce corrupt RTF for inputs containing a “\” character. (#1428)

• [Fix] Fixed page-by-page scrolling after adjusting the font size. (#1425)

• [Fix] Fixed word wrapping in the report. In particular, an unwrappable word in the Data | Description field no longer crashes the report, nor does it produce a 50-line blank space. Instead, it prints with “+” continuations. (#510)

MFrac, MPwri, MWell

• [Fix] Fixed a Log File Importing bug where the depth sampling range could appear in the row number field for some LAS files. (#1736)

• [Fix] Fixed data corruption in the Log File Importing module when Critical Stress is set to Generate. (#1734)

• [Fix] Fixed enabling and disabling of the 3D Export to Exodus command. (#1353)

Simulator

• [Enhancement] Added a new “Proppant Distribution Style” option to the Auto Design Treatment Schedule. (#1567)

  This option enables auto design of the treatment schedule based on:

  1. A maximum proppant concentration,
  2. A target concentration per unit area, or
  3. A target dimensionless fracture conductivity.

  The Proppant Transport Methodology option controls the available Proppant Distribution Styles:

  Proppant Transport Methodology	Proppant Distribution Styles
  Conventional & Conventional (Link Proppant)	All
  Tip Screen-Out (TSO) & Frac Pack	All but “maximum proppant concentration”

• [Enhancement] Added code for pseudosteady-state and constant BHFP solutions using the effective wellbore radius concept. See SPE 95941.

• [Enhancement] Added multilayer (limited-entry) fracture interaction. This new feature includes the effects of moduli/stiffness and fluid leakoff. (#1436, #1487)

• [Enhancement] Added support for coiled tubing. (#1460)

• [Enhancement] Added support for pressure-dependent leakoff. (#1411)

  The new “Pressure Dependent Leakoff” table enables the user to increase or decrease the leakoff and spurt loss coefficients as a function of pressure. This is helpful for modeling leakoff in naturally fractured reservoirs.

  When fracturing a naturally fractured formation, the pressure in the fracture may approach the critical pressure. When the critical pressure of the formation is reached, natural fractures open and accelerated leakoff occurs. A zero slope on the Nolte plot may characterize this period of accelerated leakoff.

• [Enhancement] Enhanced calculation to determine the fluid loss per unit area at the wellbore and the average in each layer. Rather than assuming a large fluid loss (i.e., fracture efficiency goes to zero), the code now uses a general integral formulation. (#1740)

  This currently affects only MPwri.

• [Enhancement] Increased the Treatment Schedule’s maximum size from 30 to 200 entries. (#1392)

• [Enhancement] Standardized NPV output in the presence of multiple parallel fractures.

• [Fix] Fixed a crash in the fluid type dependent Fluid Loss model when the designed volume was less than the pumped (Real-Time) volume. (#1657)

• [Fix] Fixed a crash when all of the n′ and K′ values for a fluid were zero. (#1519)

• [Fix] Fixed an Auto Design bug where the simulator could stop prematurely if the initial time step was very small or if the fracture length was less than a predefined value. (#1488)

• [Fix] Fixed calculation of the coiled tubing reel volume. (#1802; fixed in 5.30.2719 only)

• [Fix] Fixed the spurt loss calculation for stage dependent fluid loss. (#1548)

• [Fix] For a banking fluid (i.e., high settling velocity), some Frac Pack cases would incorrectly show that the fracture did not reach the settled bank or packed concentration. This affected cases that tried to place more proppant in the fracture than it could physically hold. (#1489)

• [Fix] If all treatment schedule stages had a zero rate, the simulator ran forever. (#750)

• [Fix] Modified the constant pressure outer boundary solution to match SPE 6015, Raghavan.

• [Fix] Support 100% CO₂ and 100% N₂ in Real-Time mode. (Design mode was already supported.) (#1503)

• [Fix] The Auto Design Treatment Schedule now optimizes the final input proppant concentration even if the calculated concentration per unit area or the calculated dimensionless conductivity is less than the target value. (#1743)

• [Fix] The design mode solution for multi-shutins (e.g., two minifracs that close) could result in the last proppant element of the last stage screening out at the wellbore. The leading stage element would also show the wrong inlet concentration. (#1490)

Input Screens

• [Enhancement] Added a lithology symbol column to the Fluid Loss zones table. (#1409)

• [Enhancement] Added browse (“...”) buttons next to the radio buttons on the Options/Proppant screen for the Wellbore-Proppant Effects and the Fracture-Proppant Effects options. (#1030)

• [Enhancement] Added keyboard accessibility to the Graphical Treatment Schedule. (#832, #1398)

• [Enhancement] Developed an improved Log File Importing module for mechanical rock properties. This new module allows for importing, generating, and calculating mechanical rock properties from a number of different input data sources (LAS, Gamma Ray, etc). (#1467)

  A property generation (parameter mapping) routine in the Log File Importing module can associate specific lithology properties with the imported mechanical rock properties. The module is capable of importing these generated properties. Three options are available for the automatic selection of zones:

  1. By layering from a mapping parameter,
  2. By parameter threshold (stress, Young’s Modulus, Gamma Ray, etc. variance by a specified value), or
  3. By depth range and increment.

• [Enhancement] Moved Time Dependent Fluid Loss to its own tab. (#1410)

• [Enhancement] Sort the Select Lithology Symbol screen. (#1037)

• [Enhancement] When error checking in the Fluid Loss and Rock Properties screens, move the cursor to the appropriate row when the depth sequence is out of order. (#1625)

• [Fix] Made it easier to see the splitter bar in the Graphical Treatment Schedule. (#1506)

• [Fix] The CO₂ and N₂ Rates (for foam jobs) now come across as a required parameter in the Graphical Treatment Schedule. (#1157)

• [Fix] The Fracture Pressure Table dialog (in MWell) was giving spurious error messages when the Fracture Pressure Table time sequence increased faster than the Near Wellbore Effects Table time sequence. (#1403)

Reports

• [Enhancement] Added Average Fracture Permeability and Screen-Out Time to the Proppant Design Summary table. (#1553)

• [Enhancement] Added concentration per unit area (carea) and dimensionless fracture conductivity (fcd) columns to the Automated NPV Design table in the Auto-Design report. Also added the number of multiple parallel fractures to the table title, to make it easier to interpret the numbers. (#1554)

• [Enhancement] Added the Proppant Design Summary table to the main report. (#1553)

• [Enhancement] Added Upper Frac Height (TVD) and Lower Frac Height (TVD) (for vertical fractures), and Center of Perfs (TVD) (for horizontal fractures), to the Fracture Propagation Solution summary table. (#1588)

• [Fix] Fixed a crash in the Selected Sections feature of the report. (#1414)

• [Fix] Fixed a crash in the Summary Report when generating a report for an NPV case. (#1389)

• [Fix] Fixed column header wording in the fluid type dependent Fluid Loss report. (#1405)

• [Fix] In the Proppant Transport report, fixed display of uninitialized data for zones with no fracture. (#1572)

• [Fix] Restored the Sand Transport Summary Table to the Summary Report. (#1389)

Plots

• [Enhancement] Added keyboard accessibility to the Plot | Configuration command on the main menu, for composite plots. An example of a “composite plot” is the Stress, Width Profiles, Width Contours plot. (#1372)

• [Fix] Fixed a crash in the (Scaled) Thermal/Water Front Profiles plot in MPwri. (#1561)

• [Fix] Fixed a crash while drawing tubing data in some 3D plots. (#1479)

• [Fix] Disable the “Friction Plot” button when there is no friction data. (#403)

• [Fix] Fixed importing from read-only files. (#1656)

• [Fix] Fixed the caption in the Add Fluid screen. (#1384)

MinFrac

• [Enhancement] Added a Manage Points feature, to allow the user to rearrange and delete Time of Closure points. (#1307)

• [Enhancement] Allow the tabs at the top of the Analysis Wizard to wrap to multiple lines. (#1649)

• [Fix] Added an error message for “Simulation Using Base Data” and “Simulation Using History Match Data” when no scales exist. Previously, this condition gave no user feedback. (#1291)

• [Fix] Added units to the Edit Imported Data spreadsheet. (#1537)

• [Fix] Combo boxes dealing with the time of closure (TC) point now remember the last selection. (#1729)

• [Fix] Display the correct data in the Simulation Using Base Data and Simulation Using History Match Data screens, when using a non-default time of closure. (#1648)

• [Fix] Fixed a user interface glitch on Select Analysis if none of the required pressure data was available. (#1464)

• [Fix] Fixed a user interface glitch while importing an ASCII text file from the Data | Options screen. (#1527)

• [Fix] Replaced an overly technical error message in the Analysis Wizard when MView was not installed. (#520)

Plots

• [Enhancement] Added the ability to rearrange Time of Closure points for the report. (#1319)

• [Enhancement] Added Young’s Modulus and Fracture Toughness to the Base Data section on the report. (#41)

MProd

History Match Simulation Option

MProd now has an option to history match measured production data with simulated data. This option provides the user with an objective methodology for determining unknown or uncertain parameters (through regression). The procedure is implemented by parametric optimization to minimize the error (standard deviation) between the measured and history matched results.

The history matching process allows the user to history match on various parameters depending on whether the well is unfractured or fractured. For an unfractured well, the user has an option to history match on the following parameters:

1. Reservoir drainage area (closed system),
2. Permeability,
3. Reservoir aspect ratio, and/or
4. Wellbore skin.

For the fractured well, the user has an option to history match on one or all of the following parameters:

1. Reservoir drainage area (closed system),
2. Permeability,
3. Reservoir aspect ratio,
4. Fracture length, and/or
5. Dimensionless fracture conductivity.

Overlay Measured Data

If the Production Simulation Option is selected the user now has an option to overlay measured data for comparison. If the Overlay Measured Data option is checked the user will be prompted in another screen to enter either the measured rate or bottomhole flowing pressure versus time. This data will then be overlaid on the numerical simulation results.

Fracture Design Optimization

Fracture Design Optimization is not a new concept, but it has received great attention in the last few years due to the concept of “Unified Fracture Design” as presented by Econimides, Valko and others. Fracture Design Optimization was first addressed by Prats in 1961. It enables the user to find the optimum (i.e., maximum production) fracture design (length, width, conductivity) for a given mass of proppant injected. MProd provides the user with the numerical values for fracture width, length, penetration ratio, dimensionless conductivity, conductivity, concentration/area, productivity index and productivity ratio in the optimum design. These values can be used as input to MFrac, which can automatically schedule a treatment to create the optimum fracture.

McGuire and Sikora Type Curves

An Optimization Diagnostic Plots option for McGuire and Sikora Type Curves has been added. Now the user can generate these famous diagnostic plots for rectangular shaped reservoirs.

Optimum Fracture Performance Curves

Optimum Fracture Performance Curves have been added that display the optimum dimensionless conductivity and fracture penetration for a given proppant number or mass of proppant injected. Diagnostic plots for the productivity index and dimensionless productivity are also included as a function of dimensionless conductivity for various proppant numbers.

Pseudosteady-State Analysis Solution

An advanced pseudosteady-state solution for a well with a finite conductivity vertical fracture has been implemented based on the reservoir/fracture domain resistivity concept formulated by Meyer (see SPE 95941). The resulting pseudosteady solution is presented in the form of the dimensionless productivity index as given in Appendix L of the User’s Guide.

Some of the major advantages of this pseudosteady solution for finite conductivity vertical fractures are:

1. The methodology is based on fundamental principles,
2. The solution is analytical,
3. The equations are formulated for rectangular shaped reservoirs,
4. The solution and concepts are easily understood and implemented, and
5. The methodology accounts for a piecewise continuous linearly varying fracture conductivity.

Variable Fracture Conductivity Data

A Variable Fracture Conductivity option is now available in MProd for a fractured well. This option allows the user to input Fracture Conductivity or Dimensionless Conductivity as a function of Fracture Position. The numerical simulator uses this data to calculate the effective fracture conductivity and dimensionless conductivity.

The input dialog allows for a piecewise continuous linearly varying fracture conductivity including: proppant tail-ins, over-flushing, pinch zones, choked flow (external skin, fracture), etc.

Wellbore Skin Factors

The dimensionless pressure drop at the wellbore face as a result of damage (positive value) or stimulation (negative value) is commonly referred to as Well Skin.

No Fracture

• Base. The base wellbore skin factor is the skin before the well is stimulated, or simply a base skin that a stimulated well can be compared with to determine a productivity increase index.

• Stimulated. The stimulated wellbore skin factor is used to calculate the well productivity. The base wellbore skin factor for an unfractured well is used for the base productivity for comparison with the stimulated case. In other words, the dimensionless productivity index is the ratio of the stimulated to the base case productivity.

Fractured Well

• Prefrac. The prefrac wellbore skin factor is the wellbore skin before the well is fractured. The prefrac skin factor is used in the calculation of the flow resistivity in the near wellbore region. For high conductivity fractures, the flow entering the wellbore in the near well region is normally negligible and positive prefrac skin values will have a minor effect when the fracture length is much greater than the wellbore radius (or the effective wellbore radius). If the prefrac skin is negative, the fracture resistivity model simulates a reduced resistance in the near wellbore region resulting in an increased productivity. This is especially true for short fractures with large negative prefrac skins.

• Reference. The productivity from a well with a reference wellbore skin factor is used for comparison with the fractured well productivity. For the fractured well with a prefrac skin, the productivity increase is the ratio of the fractured well productivity to that of a well with the reference wellbore skin factor as given by this input value.

Effective Propped Payzone Height

The capability for a partially propped payzone for a fractured well has been added in the formation data dialog.

Other Changes

• [Enhancement] Added a Simulation Data window and Run Options screen. (#1465, #1511)

• [Enhancement] Expanded the internal PVT table and the Gas PVT spreadsheet from 20 to 200 rows. (#124)

• [Enhancement] Separated storage for the Production Data values for the Production Boundary Conditions of Pressure and Rate. Previously, changing between Pressure and Rate would overwrite the values for the other boundary condition. (#1510)

• [Enhancement] The original Tri-Linear Solution assumed flow could only enter the wellbore through the fracture.

  Although the June 2006 release did account for flow through the wellbore, an enhancement has been implemented 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 (i.e., fracture skin). (#1749)

• [Fix] Always recalculate dimensionless conductivity when exiting the Formation Data dialog. (#1747)

• [Fix] Fixed Productivity Ratio calculation for Production Simulation cases with an initial rate of zero. (#1750)

• [Fix] Fracture skin was implemented improperly for a closed system produced at a constant bottomhole flowing pressure. The true fracture skin is now used instead of the one defined by Lee & Brockenbrough. (#1746)

• [Fix] Separate storage for the “base” and “prefrac” Wellbore Skin Factors in the file. This change affects all Production Simulation models. (#1716)

MView

• [Enhancement] New velocity unit: km/h. (#1517)

• [Enhancement] Prompt the user before stopping acquiring input data, and before stopping sending output data. (#720)

• [Fix] Changing the output unit for a temperature parameter now correctly converts data from the old unit to the new unit. (#1502)

• [Fix] Crash and/or data corruption when parsing a file with bytes in the range 0x80 to 0xFF.

• [Fix] Fixed handling of temperature shift values. (#1502)

• [Fix] Fixed units on the Preview Plot when importing MFrac files. (#1502)

• [Fix] Fixed a crash in Graphical Edit when editing more than 16 curves. (#1696)

• [Fix] Fixed configuration of plots with multiple parameters on one axis when no data is available. (#1719)

• [Fix] Fixed the “X parameter must be a nondecreasing sequence” error message in Graphical Edit mode. (#134)

• [Fix] Made the fonts in Graphical Edit mode consistent with the other apps. (#1367)

MNpv

• [Enhancement] Added a Simulation Data window and Run Options screen. (#1465)

• [Fix] Fixed a crash in MNpv when plotting more than 50 years’ worth of MProd data. (#1604)

• [Fix] Fixed data loss in the NPV plots when opening the Unit Cost table. (#1671)

• [Fix] Fixed error in the generation of NPV/DROI data for the variable revenue/unit volume option. This affected the Production P.V. Rev. and Additional Frac Rev. columns of the Net Present Value Solution section of the report, and the associated plots. (#1748)
