Where: ELgas is a gas well’s economic limit in thousand standard cubic feet per month (MSCF/month).Po, Pg are the current prices of oil and gas in dollars per barrels and dollars per MSCF respectively.LOE is the lease operating expenses in dollars per well per month.WI is working interest, as a fraction.NRI is net revenue interest, as a fraction.GOR is gas/oil ratio as bbls/MSCF.Y is condensate yield as barrel/million standard cubic feet.T is production and severance taxes, as a fraction.

For the initial placement, the wells were drilled at locations with high porosity-thickness weighted initial oil saturations, i.e., high HphiSoi. In this case, Soi is the initial oil saturation. Regions with high HphiSo were targeted for oil placement after satisfying the set saturation threshold. To optimize the placement of infill-well, a new HphiSo map is generated at any time to evaluate the saturations at potential locations of the well. In some cases, the location of a well can be optimized by comparing the well’s cumulative production of oil, water cut or gas-oil-ratio (GOR) from two or three candidate locations. In this case, the location that gives the highest cumulative oil production, lowest GOR and Water cut is selected. The gas wells are placed in the crestal region of the gas cap using the corresponding porosity-thickness weighted gas saturation HphiSg maps, where Sg is the gas saturation. Figure 3 shows a typical HphiSo map used to identify locations of production wells in the model.
