1. A computer implemented method comprising:
determining, by a processor of a computing device, actual trapped gas saturation data of a subsurface formation from maximum gas saturation data, maximum trapped gas saturation data, and actual gas saturation data;
determining, by the processor of the computing device, pseudo-maximum gas saturation data from the actual trapped gas saturation data, the maximum trapped gas saturation data, and the actual gas saturation data;
determining, by the processor of the computing device, relative permeability data of the subsurface formation by mapping the pseudo-maximum gas saturation data along a drainage curve; and
affecting a hydrocarbon production rate of a hydrocarbon production well located in the subsurface formation by adjusting, by the processor of the computing device, fluid injection into an injection well located in the subsurface formation based on the relative permeability data.
