Claim Text:
1. A computer-implemented method of modeling hydrocarbon flow through a hydrocarbon bearing formation, the method comprising: determining, by a computer system, a kerogen-wet porosity within a portion of a reservoir rock formation, based on one or more formation parameters associated with the portion of the reservoir rock formation; determining, by the computer system, a water-wet porosity within the portion of the reservoir rock formation, based in part on the kerogen-wet porosity; simulating, by the computer system, hydrocarbon movement through a first small model volume representing the kerogen-wet porosity within the portion of the reservoir rock formation; simulating, by the computer system, hydrocarbon movement through a second small model volume representing the water-wet porosity within the portion of the reservoir rock formation; determining a matrix porosity and permeability for the portion of the reservoir rock formation, based on the simulated hydrocarbon movement through the respective first and second small model volumes; simulating, by the computer system, hydrocarbon movement through a large scale formation model of the reservoir rock formation, based on the matrix porosity and permeability determined for the portion of the reservoir rock formation; and estimating, by the computer system, future hydrocarbon production for drilling one or more boreholes within the reservoir rock formation, based on the simulated hydrocarbon movement through the large scale formation model.
