Primary oil migration from a source rock has been simulated using a computer. The simulation model is based on a finite difference solution of one‐dimensional fluid‐flow differential equations. Oil generation is simulated by the time‐temperature index. Shale porosity is reduced by compaction. Oil saturation rises as organic matter is conversed to oil, and the source‐rock porosity decreases during burial. When oil saturation reaches an irreducible level, surplus oil is expelled by capillary and excess pore fluid pressure. The model is applied to an actual case. Oil generation and migration from a possible source rock in Kuwait is simulated. A reasonable estimate of the time of oil expulsion is obtained. even though values of several parameters had to be assumed. The results confirm the validity of the model and point to the possible use of such computer simulation models in oil exploration.
