Furthermore, there is a term called Hydrocarbons Initially in Place (HCIIP) that is used for either oil or gas. Similar to OIP, HCIIP is calculated using measures of the
Calculate the original oil in place (OOIP) of an oil reservoir if the drainage area = 1600 acres, thickness=30 ft, porosity=0.3 and Sw=0.2 at the initial reservoir pressure = 4000 psi. Note that the reservoir bubble point pressure is 3000 psi. Your answer should be in [reservoir barrels] or [rb]. The formation volume factor of an oil or condensate (B o) relates the volume of 1 lbmol of liquid at reservoir conditions to the volume of that liquid once it has gone through the surface separation facility. The oil has an API gravity of 42° and gas-oil ratio of 600 scf/STB. The specific gravity of the solution gas is 0.65. The following additional data are also available: • Reservoir area = 640 acres • Average thickness = 10 ft • Connate water saturation = 0.25 • Effective porosity = 15% Calculate the initial oil in place in STB. The formation volume factor (FVF) relates the volume of oil at stock tank conditions to the volume of oil at elevated pressure and temperature in the reservoir. Values typically range from approximately 1.0 bbl/STB for crude oil systems containing little or no solution gas to nearly 3.0 bbl/STB for highly volatile oils.
