Abstract
Systems, methods, and computer program products can be used for determining the amount of oil removed by a miscible gas flood. One of the methods includes identifying locations of oil within a volume representing a reservoir rock sample. The method includes identifying locations of gas within the volume. The method also includes determining the amount of oil removed based on locations within the volume where oil is either coincident with the gas or is connected to the gas by a continuous oil path.
Claims21
A computer implemented method for enhanced oil recovery from a porous medium, the method comprising:
- identifying one or more representations of oil within voxels representing the porous medium;
- identifying one or more representations of gas within the voxels representing the porous medium;
- and
- determining one or more of the voxels representing oil and gas to estimate the amount of oil that is recoverable from the porous medium.
A system for enhanced oil recovery from a porous medium, the system comprising:
- one or more processor devices;
- memory operatively coupled to the one or more processor devices;
- and
- computer storage storing executable program instructions to cause the system to:
- identify one or more representations of oil within voxels representing reek the porous medium;
- identify one or more representations of gas within the voxels representing the representing porous medium;
- and
- determine one or more of the voxels representing oil and gas to estimate the amount of oil that is recoverable from the porous medium.
A computer program product tangibly stored on a non-transitory storage device, for enhanced oil recovery from a porous medium, the computer program product comprising instructions to cause a system to:
- identify one or more representations of oil within voxels representing reek the porous medium;
- identify one or more representations of gas within the voxels representing the porous medium;
- and
- determine one or more of the voxels representing oil and gas to estimate the amount of oil that is recoverable from the porous medium.
