Parameter Value Description
sizeX Length size of the reservoir drainage box. X-direction, parallel to the well, [ft]
sizeY Width size of the reservoir drainage box. Y-direction, perpendicular to the well, [ft]
sizeZ Reservoir height. Z-direction, [ft]
Kx Horizontal permeability in X-direction, [mD]
Ky Horizontal permeability in Y-direction, [mD]
