GMI•SFIB 5.3 bundles the functionality available in the internally released Updates 1-2 of SFIB 5.2, and releases previously-proprietary functionality to all users. A number of additional functional improvements and features have also been added. The new features include the following.

 • In BSFO

    • Multiple planes of weakness can be used to simulate fractured / jointed rock and coal

    • Orthotropic strength

    • Elasto-plasticity with residual strength

    • Anisotropic strength criteria are now available with time-dependent (e.g., thermo-poroelastic or chemo-poroelastic)
      modes of BSFO

    • Effect on stability of wellbore pressure leakage into near-well fractures and faults

    • Flexible axis limits in stability plots to evaluate mud weights above S3 and below Pp

    • Improved 3D to 2D stress mapping for more accurate FEA poroelasticity analysis

 • In GFLR, new analyses for sanding predictions

    • Maximum drawdown for a given effective strength

    • Minimum safe effective strength for a given drawdown

 • In BROT_3

    • Analysis to predict stresses based on observations of breakout rotations due to fault slip on faults that do not       intersect the well

 • Improved handling of Case Studies

      • Ability to create a Case Study from the input data of the current module

      • Ability to save Case Studies with new names

      • An improved interface for building a Case Study from GMI•WellCheck^TM input files

 • In CSTR

      • It is now possible to display contours of tensile crack inclination incTF

      • Axes can be rescaled under user control

• A simplified Feature Position calculator is now available from the Help menu

• Consistent definitions are now used for wBo throughout the application

• Units handling is now consistent with other GMI applications

• It is possible to define a preferred data location (Last File or UserData)

• The positions of Radial and Circumferential Profiles can be selected interactively

• SFIB now understands the GMI “project” file

• A number of bugs have been identified and fixed, and calculations have been improved, including

    • Lade calculations have been modified to minimize zones where no result is displayed in GFLR Output plots

    • Computations have been improved to avoid contouring artifacts from distorting GFLR Output plots

    • GFLR Summary plots maintain an inverse color scale for tensile failure

    • Denser gridding and increased stability in Output plots in thermo-poroelastic and chemo-poroelastic rock
