How is OOIP calculated?

How is OOIP calculated?

The OOIP is calculated by this equation is in reservoir barrels (RB), and the other parameters are defined as follows: \$e = effective porosity (fraction), h = pay height, ft, and Sw = water saturation (fraction).

How do you find oil in place?

The simplest method to determine the quantity of original oil and gas in place in conventional reservoirs is volumetric analysis. First, the bulk volume of the reservoir is determined by knowing the reservoir boundaries and formation thickness. Next, the pore volume is determined based on rock porosity.

What does Ooip mean?

Oil in place (OIP) (not to be confused with original oil-in-place (OOIP)) is a specialist term in petroleum geology that refers to the total oil content of an oil reservoir.

What is the difference between Stooip and Ooip?

The full form of these two abbreviations are as follows: STOIIP = Stock Tank Oil Initially In Place. OOIP = Original Oil In Place, or. STOOIP = Stock Tank Original Oil In Place.

What is the recovery factor?

The recoverable amount of hydrocarbon initially in place, normally expressed as a percentage. The recovery factor is a function of the displacement mechanism. An important objective of enhanced oil recovery is to increase the recovery factor.

How do you calculate capital recovery factor?

The CRF is equal to [r·(1+r)T]/[(1+r)T–1], where r is the appropriate discount rate and T is the economic lifetime of the NPP. The appropriate discount rate is usually a weighted average cost of capital (debt and equity), consistent with the discount rate for calculating IDC.

How do you calculate initial oil in place example?

Calculate the initial oil-in-place (N) of an oil reservoir if A=1,600 acres, h=32 ft, ϕ=22%, Siw=20%, and Boi=1.23 bb1/STB. The initial gas deviation (also called compressibility) factor, zi, is calculated at the initial pressure, pi, of the gas reservoir….Example.

A=1,320 acres T=200°F
ϕ=0.175 zi=0.916
Siw=0.23

What is the difference between a reserve and oil in place?

Oil initially in place (OIIP) is the amount of crude oil first estimated to be in a reservoir. Oil initially in place differs from oil reserves, as OIIP refers to the total amount of oil that is potentially in a reservoir and not the amount of oil that can be recovered.

What Ooip stand for?

From Wikipedia, the free encyclopedia. Oil in place (OIP) (not to be confused with original oil-in-place (OOIP)) is a specialist term in petroleum geology that refers to the total oil content of an oil reservoir.

What does Ooip stand for?

Original oil in place (OOIPoriginal oil in place) and original gas in place (OGIPoriginal gas in place) refer to the total volume of hydrocarbon stored in a reservoir prior to production.
