Different depositional environments caused serious heterogeneity in this oilfield. Interlayer heterogeneity is known discovered hydrocarbon accumulations and their associated potential The entire resource base (defined here as Total Petroleum-initially-in-place) is price” rules to the calculation of proved reserves in various situations are
1 Sep 2014 The Russian statistics agency provides data on hydrocarbon production and energy consumption for production and transportation of oil and gas.
Oil in place (OIP) is a specialist term in petroleum geology that refers to the total oil content of an The oil in place is calculated as the product of the volume of porous as stock tank original oil-in-place (STOOIP) or stock tank oil-initially-in- place (STOIIP), HCIIP Calculation and Formula on the Petroleum Geology Forums

To calculate volume of original oil in place volume measured in acre-feet, use the following formula:. 17 Feb 2016 Original oil in place (OOIPoriginal oil in place) and original gas in place The basic equation used to calculate recoverable oil reserves is. Step 5. Calculate the gas solubility when all the trapped gas is dissolved in the oil by applying Equation 14-4:. 10 Apr 2016 To estimate oil initially volume in place, the following formula is a volumetric calculation for oil. STOIIP. Where; In reservoir engineering, volume of hydrocarbon in a reservoir called volume in place (oil and/or gas). Volume of Oil Reservoir Calculations. Gas Reservoir Volume Parameter Equations and Equalities. Rock Volume Original Oil-in-Place (OOIP) Calculations. Field Units. 4 Jan 2018 1 Purpose of Volumetric Calculations: 2 Equations: 2.1 Original Oil-In-Place: 2.1. 1 Metric Calculation: 220.127.116.11 Variables: 2.1.2 Imperial

Estimation of the in place oil and gas volumes and its recoverable part requires the volume of the reservoir to be calculated through maps and OOIP: Oil Initial in Place. GIIP: Gas Initial in 5.1 Calculation of Gas Reserves. Volume of gas
I. Calculating Oil in Place by the Volumetric Method Oil in place by the volumetric method is given by: Where: N(t) = oil in place at time t, STB V b = 7758 A h = bulk reservoir volume, bbl 7758 = bbl/acre-ft A = area, acres h = thickness, ft φ(p(t)) = porosity at reservoir pressure p, fraction S Calculating oil volume in place. To calculate volume of original oil in place (OOIP original oil in place)in barrels from volume measured in acre-feet, use the following formula: where: 7758 = conversion factor from acre-ft to bbl barrels; A = area of reservoir, acres from map data h = thickness of reservoir pay, ft Φ = porosity (decimal, not percent) Calculation of hydrocarbon reserves can be done by using formula of original oil in place (OOIP). The formula is a function of volumetric (height x area), porosity(¢) and saturation water (SW) with the mathematic equation: OOIP = 7758 x (¢) x (1-SW) x volumetric. Before calculating the reserves, we need to compute those elements of function. Alternatively, the production history can be fitted to a curve to estimate future oil production (decline curve method). The analogous term original gas-in-place (OGIP) is used to refer to the total natural gas in a reservoir. 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 total reservoirs volume correcting for the non reservoir rock, the porosity and the water OOIP = original oil in place (m3 or bbl) OOIPT = original oil in place (tonnes) REServes - Oil and Gas Reserves Calculate reserves 6: RF = (Sxo - Sw) / (1 - Sw) or from decline curve analysis or analogy. 7: Roil = RF * OOIP 8: Rgas = RF * OGIP. Where: AREA = reservoir area (acres or m2) Bg = gas formation volume factor (fractional)
