Oil in place is the total hydrocarbon content of an oil reservoir and is often abbreviated STOOIP, which stands for Stock Tank Original Oil In Place, or STOIIP for Stock Tank Oil Initially In Place, referring to the oil in place before the commencement of production. In this case, stock tank refers to the storage vessel It is also known as Oil in Place (OIP) and Stock Tank Original Oil in Place (STOOIP). Petropedia explains Stock-tank Oil Initially in Place (STOIIP) Stock-tank Oil Initially in Place is the volume of oil present in a hydrocarbon reservoir before the start of any production in equivalent volume that the oil will occupy when it is stocked in a storage tank. 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]. 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 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)
This provides an estimate of the hydrocarbon in place from which ultimate the influence of drive mechanisms on the original oil in place (OOIP) estimates.
It is also known as Oil in Place (OIP) and Stock Tank Original Oil in Place (STOOIP). Petropedia explains Stock-tank Oil Initially in Place (STOIIP) Stock-tank Oil Initially in Place is the volume of oil present in a hydrocarbon reservoir before the start of any production in equivalent volume that the oil will occupy when it is stocked in a storage tank. 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.

As this quantity cannot be measured directly, it has to be estimated from other parameters measured prior to drilling or after production has begun. The initial or original oil in place can be estimated from the volumetric equation: (5.2.46) N = 7 , 758 V b ϕ ( S o i ) B o i = 7 , 758 A h ϕ ( 1 − S w i ) B o i
This method provides a 4.4％ of Original Oil in Place（OOIP）incremental oil recovery over water hydrocarbon saturation in each reservoir, and difficulty in.
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 17 Feb 2016 Original oil in place (OOIPoriginal oil in place) and original gas in place (OGIP original gas in place) refer to the total volume of hydrocarbon The original oil in place (OOIP) was higher than 4 billion bbls. The reservoir was shallow and consisted of an alternating sequence of unconsolidated sands with 9 Apr 2019 Original gas in place (OGIP) is again the same volumetric calculation but for natural gas reservoirs. Finally, hydrocarbons initially in place
27 Sep 2018 Usually two conventional methods use to estimate the Original Oil In Place (OOIP ) very quickly. These two methods are volumetric method and
the volumetric calculation, the total of original oil inplace in the Dalimo Field is about 153.30 MMSTB. From Original Oil In Place (OOIP) and reserve estimation. The Xing-28 block had 2.05 km 2, reservoir thickness of 3 m, and original oil in place (OOIP) of 0.96 million tons. It had an anticline structure and a gas cap of 1.08 km 2 with a thickness of 2.6 m. It also had edge water, and the reservoir depth was 1650 to 1730 m. Original oil in place (OOIP original oil in place) and original gas in place (OGIP original gas in place) refer to the total volume of hydrocarbon stored in a reservoir prior to production. Reserves or recoverable reserves are the volume of hydrocarbons that can be profitably extracted from a reservoir using existing technology. Oil-in-place is also known as stock tank original oil-in-place (STOOIP) or stock tank oil-initially-in-place (STOIIP), referring to the oil in place before the commencement of production. In this case, stock tank barrels refers to the volume of oil after production, at surface pressure and temperature (as opposed to reservoir conditions).

It is also known as Oil in Place (OIP) and Stock Tank Original Oil in Place (STOOIP). Petropedia explains Stock-tank Oil Initially in Place (STOIIP) Stock-tank Oil Initially in Place is the volume of oil present in a hydrocarbon reservoir before the start of any production in equivalent volume that the oil will occupy when it is stocked in a storage tank. Petrole-um? | Original Oil in Place And Formation volume factor. This video describes how a carbonated drink can be used to understand original oil in place (OOIP) Email: petroleum.studentsurvival Volumetric calculations of Original Oil IN Place OOIP by using Crystal ball software (Add-on for Excel) As you know two main ways for volumetric calculations (Deterministic and Probabilistic). 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]. The reservoir thickness and radius were 300 feet and 2,500 feet respectively, the reservoir temperature was 120[degrees]F and the original oil in place (OOIP) was 500 million stock tank barrels (MMSTB).
