Quantitative analysis of the influence of capillary pressure on geologic carbon storage forecasts case study: CO2-EOR in the Anadarko basin, Texas

•Capillary pressure is an important control on fluid flow in numerical models.•Adding capillary pressure increased forecasts of oil recovery, decreased forecasts of water production, and increased forecasts of CO2 solubility trapping while having little impact on the pressure distribution.•The strength of the capillary pressure curve and the shape of the relative permeability curve defines the fluid mobility.
