| 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] | |
| z0 | Z location of the heel of the well. For the centrally placed well is equal to 0.5*reservoirHeight, [ft] | |
