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.
Claims15
A computer implemented method for determining an amount of oil recoverable from porous reservoir rock by a miscible gas flood, the method comprising:
- identifying locations of oil within a volume of voxels representing an original state of the porous reservoir rock;
- identifying locations of gas within the volume of voxels representing the original state of the porous reservoir rock;
- and
- determining voxels within the volume where oil is either coincident with gas or is connected to gas by a continuous oil path to estimate the amount of oil that is recoverable from the porous reservoir rock.
A system for determining an amount of oil recoverable from porous reservoir rock by a miscible gas flood, 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 locations of oil within a volume of voxels representing a first state the porous reservoir rock;
- identify locations of gas within the volume of voxels representing the first state the porous reservoir rock;
- and
- determine voxels within the volume where oil is either coincident with the gas or is connected to the gas by a continuous oil path to estimate the amount of oil that is recoverable from the porous reservoir rock.
