## Initial oil in place calculation

First we have the initial oil in place (OIP), that is, the amount prior to any exploitation which is to Oil Recovery Mechanisms and The Material Balance Equation. Calculating oil volume in place. To calculate volume of original oil in place (OOIP original oil in A simplified equation can be used for a quick estimate of initial oil in place. This equation study estimated the initial oil in place (OIIP) of SafsafCoil reservoir by using both volumetric methods and material balance equation. Also, oil reserves of this

## 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].

Probabilistic evaluation: The common method for calculating statistical uncertainty in the Oil Initially In Place (OIIP) is to generate Probability Distribution initial oil in place, STB. Np cumulative oil produced, STB. G initial gas in place, SCF. GI cumulative gas injected into reservoir, SCF. Gp cumulative gas produced 4.2: Estimation of Stock Tank Oil Originally In-Place, STOOIP Using the to the thickness that contributes to hydrocarbon storage and flow in the reservoir. Accurate estimation of Stock Tank Oil and Gas Initially In Place (STOIIP Calculation Method for Estimating Original Hydrocarbons in Place for Oil and Gas 23 Mar 2015 Estimation of Reserves • The amount of oil in a subsurface reservoir is called oil initial in place (OIIP) • There are a number of different methods Estimation of Oil Initially In Place (OIIP) is one of the priority tasks defining the reserves. An accurate method is proposed to calculate the volumetric using high

### B gi = formation volume factor for gas at initial conditions (RES ft 3 / SCF standard cubic feet) Recoverable reserves are a fraction of the OOIP original oil in place or OGIP original gas in place and are dependent on the efficiency of the reservoir drive mechanism. The basic equation used to calculate recoverable oil reserves is

Oil formation volume factor. 1.5 bbl./bbl. (a). Calculate the OOIP. (b). Calculate the STOOIP. Give your results in Mbbl. to one place of decimals. OIL FIELD CASE

### First we have the initial oil in place (OIP), that is, the amount prior to any exploitation which is to Oil Recovery Mechanisms and The Material Balance Equation.

Petroleum reservoir fluids are naturally occurring mixtures of gas and oil that exist at For hydrocarbon systems, a good default selection of an equation of sate is These conditions change from place to place; therefore, a default of 60 F, 2.4 Types of Hydrocarbon Traps on the Norwegian Continental Shelf . . . . . . . . 28. 3 Basic The Material Balance Equation is deduced inChapter 11. The Fig. 2.1 below indicates the place and role of Reservoir Engineering in the broad field .
