Oil Formation Volume Factor (Bo). Reservoir pressure is 2500 psia and Oil volume is 1500BBL at that conditions. a) what would be the volume of that oil under standard conditions? Oil formation volume factor at 2500psia is equal to ~ 1.333 . Bo - Oil formation volume factor. Petropedia - What is Oil Formation Volume Factor ... Oil Formation Volume Factor (FVF) is the volume of dissolved gas and crude oil at reservoir pressure and temperature divided by the volume of oil at standard conditions or stock tank surface conditions. It is denoted by the notation “Bo” and the purpose of calculating Oil Formation Volume oil formation volume factor - Schlumberger Oilfield Glossary Oil formation volume factors are almost always greater than 1.0 because the oil in the formation usually contains dissolved gas that comes out of solution in the wellbore with dropping pressure.
Bo. = Formation volume factor (m3/ m3) (dimensionless factor for the change in oil volume between reservoir conditions and standard conditions at surface). A second parameter, called the oil formation volume factor (Oil FVF), Bo, also has been defined to describe the shrinkage or expansion of the oil phase. Oil volume The data consisted of oils with oil formation volume factor at bubblepoint pressure ranging from 1.068 to 2.43 bbl/stb, oAPI of 17 to 46, solution gas oil ratio of 52 Formation Volume Factor (Bo) – Top Dog Engineer Formation Volume Factor (Bo) Petroleum Engineering / By Brandon Tolbert The produced volumes measured at surface conditions are never equal to the volumes at reservoir conditions because of the differences in temperature and pressure. Oil Formation Volume Factor - an overview | ScienceDirect ... 1.2.1 Oil Formation Volume Factor (FVF or Bo) By definition, the oil formation volume factor (FVF or Bo) is the volume of live oil at any T and P (not necessarily the original reservoir conditions) divided by the volume of the respective dead oil at standard conditions, 1 atm and 60°F:
Bo = 0.972 + 0.000147*F**1.175. Where F = Rs*(Gamma_g/Gamma_o)**0.5 + 1.25*T Bo = Oil formation volume factor, bbl/STB, Rs = solution GOR, scf/STB, [20 26 Sep 2017 Oil Formation Volume Factor (Bo):. The oil formation volume factor is the ratio of volume occupied in the reservoir by a volume of oil measured at Plots showing formation volume factor (Bo) versus: API gravity, original pressure, reservoir temperature, and depth. PA3. Plots showing: original pressure vs The oil formation volume factor, Bo, is a factor used to estimate the change in volume of oil as it undergoes a change in pressure and temperature. The change and generates black oil properties such as Oil Formation Volume Factor (Bo), Solution Gas-Oil Ratio (Rs), Oil Viscosity (μo) and Oil Compressibility (Co) using initial oil formation volume factor, bbl/STB. Bgi initial gas formation volume factor, bbl/SCF. Bt two-phase formation volume factor, bbl/STB = Bo + (Rsoi - Rso) Bg.
Classic Waterflooding Predicitive Models Initial water injection to water breakthrough: Buckley-Leverett Buckley and Leverett (1942) developed a mathematical approach to describe two-phase, Oil formation volume factor (Bo) .25 bbl/STB 1 Water formation volume factor (B .02 bbl/STB w) 1 Formation … Reservoir engineering Flashcards | Quizlet When gas in the reservoir it is subjected to high-pressure. This means that occupies less space in the reservoir than it would if it were brought to the surface. The gas formation volume factor Bg represents the volume of gas at reservoir conditions required to produce 1 scf or 1 scm at. Standard conditions. Reservoir Engineering Quiz Prep 2 Flashcards | Quizlet What happens to the formation volume factor of oil in a volumetric undersaturated reservoir with a weak water drive? Bo = Boi What is the formula for the recovery factor for a volumetric undersaturated reservoir with a weak water drive?
