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]
Kz		Vertical permeability, [mD]
L		Length of the horizontal part of the well, [ft]
Rw		Wellbore radius, [ft]
Bl		Liquid formation volume factor, [bbl/STB].
Ul		Liquid viscosity, [cP]
S		Skin factor, [dimensionless]
x1		X location of the heel of the well. For the centrally placed well is equal to 0.5*(boxLength-wellLength), [ft]
y0		Y location of the heel of the well. For the centrally placed well is equal to 0.5*boxWidth, [ft]
