What’s New in GEM 2024.10:

SIMULATOR FEATURE ENHANCEMENTS

CO2 Density Interpolation in Pure CO2 Grid Blocks

During CO2 injection and storage operations, as injected CO2 displaces components especially near wells, the grid blocks gradually become richer and richer in CO2, eventually containing nearly pure CO2. However, there is no gradual phase transition from gas to liquid for a pure substance due to the limited degree of freedom, resulting in a discontinuous phase density across the saturation point and causing convergence difficulties.

A new keyword *CO2-DEN-SMOOTH is introduced to interpolate phase CO2 density between liquid and vapor states for nearly pure CO2 grid-blocks. This eliminates density discontinuity during the phase change, thereby enhancing the stability and convergence behavior of the simulation. See keyword *CO2-DEN-SMOOTH in GEM manual and template data set gmghg054.dat

Component Molar Well Stream Rates through Outboard

The component molar well rate and cumulative in different surface streams can now be passed to third party applications though Outboard by using newly added sub-keyword *WELL-QMOL of *OUTLIST. Each of the component molar rates are split into four streams: OIL, GAS, WTG and INL (depending on the separator specification). This data could also be accessed by Pycontrol for updating recurrent information during a run.

IPR Table Generation

The heuristics of IPR table generation have been improved, especially for wells completed in multiple layers and exhibiting back-flow.

Three options are provided for selecting the pressure column in the IPR table, i.e., allowing equi-distance pressure, existing non-linear, or the new non-linear approach for handling backflow, respectively.

Also, in addition to keyword *IPRTAB, a command line option “-iprtab n” is provided to indicate the number of rows to be created in the IPR table. These options are useful for models running GEM coupled with third party wellbore or surface network programs.

SOLVER FEATURE ENHANCEMENTS

PDEGAB Setting for the Linear Solver Pre-Conditioner

The solver pre-conditioner degree is controlled by two keywords, *PDEGAA and *PDEGAB, which by default are set to 1 and 2, respectively. The *PDEGAB 0 removes the separator class and makes the solver convergence faster at the expense of a marginal increase in solver iterations. For the *AUTOP2D option, the selection of *PDEGAB 1 results in saving in the run time in most of the models.

A new strategy based on the number of active grid-blocks automatically sets the PDEGAB to 0, 1, or 2 resulting in considerable savings in the run time in most models tested. If necessary, this can be overridden by the explicit specification of keyword *PDEGAB in the data file or through command line option “-pdegab n”.

GEM’s end-time summary echoes the value of PDEGAA and PDEGAB for easy identification of the values used during the simulation in different runs.
