Formation volume factor equation
WebReserve = V φ S 0 b 0 × Recovery Factor Here, V is reservoir volume, φ is average porosity, S 0 is the average oil saturation, and b 0 is oil formation volume factor. Note that here porosity and saturation are estimated (using different sources of information such as well logging, well tests, and seismic data) and have their own uncertainties. WebFormation factors are used to calculate the gas well productivity index, and gas-well production under certain pressure differences can be calculated thereby: (7.31) 3) …
