What does original oil in place mean?
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 is the original gas in place?
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.
What does OOIP mean?
OOIP stands for Original Oil In Place.
What are the method of estimating oil in place?
The estimating of original oil-in-place is based on calculations using the volumetric method or the material balance method when sufficient factual data are available concerning reservoir rock, fluid properties, reservoir limits, and production performance.
Is STB the same as BBL?
1.2. 1 General definitions. Oilfield units volumes in oilfield units are barrels (bbl or B); 1 bbl=5.615 ft3 or 0.159 m3. A STB is the same volume defined at some surface standard conditions (in the stock tank) which are usually 60°F and 14.7 psi.
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 does gas in place mean?
an estimated measure of the total amount of gas contained in a reservoir and, as such, a higher figure than Recoverable Gas. May also be termed Gas initially in place (GIIP) to describe the volume of gas that exists at initial discovery.
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.
What is the difference between STOOIP and OOIP?
What is STB in oil and gas?
Definition. STB. Stock tank barrel, the volume of a barrel of oil at the earth’s surface as opposed to the corresponding volume in the subsurface.
What is set of box?
A Set Top Box is a device that allows users to view video content from specific internet video providers via the internet. Also known as a Set Top Unit, these boxes convert a digital television signal to analog to be viewed on a conventional television set, or enable cable or satellite television to be viewed.
How do you calculate oil recovery factor?
Recovery Factor = (Cumulative oil )/(Total Original Oil in place).
