## Initial oil in place formula

This page discusses various aspects of gas reservoir performance, primarily to determine initial gas in place and how much is recoverable. The equations developed can used to form the basis of forecasting future production rates by capturing the relationship between cumulative fluid production and average reservoir pressure. 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 (often purely notional) containing the oil after production. HCIIP Formula. EPGeology.com aids Exploration and Production Geologists. HCIIP Formula. Mon Nov 10, 2014 8:04 pm. The HCIIP is an acronym for Hydrocarbons Initially In Place. For Oil this is STOIIP (Stock Tank Oil Initially In Place) and for Gas it’s GIIP (Gas Initially In Place). 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]. 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. Calculate Oil in Place - Duration: 7:02. PETE TenTen 12,810 views. Flow Rate Formula Initial oil in place calculation for solution gas drive reservoir - Duration: How to calculate oil-in-place (basic - for introduction to petroleume engineering students - not all variables included.

## 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.

To calculate volume of original oil in place volume measured in acre-feet, use the following formula:. 9 Apr 2019 Stock tank oil initially in place (STOIIP) is the same volumetric calculation with it being made explicit that the volume being estimated is the 10 Apr 2016 To estimate oil initially volume in place, the following formula is a volumetric calculation for oil. STOIIP. Where;. STOIIP = stock tank oil in place, 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 Volumetric calculations for OOIP (original-oil-in-place) were carried out on each of The OOIP is calculated by this equation is in reservoir barrels (RB), and the

### 25 Sep 2019 The developed ANNs-based equation outperformed the available equations where STOIIP is the stock-tank oil initially in place at the original

## 10 Aug 2017 Therefore one of the key parameter that is being used in the oil and gas industry for calculation of initial hydrocarbon in place is porosity.

Oil Initially In Place - OIIP: The amount of crude 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

magnitude of the original oil/gas in place influences the economic Calculation of connate water saturation by recalculating the mercury-air capillary pressure In a reservoir containing volatile oil, the Walsh formulation is used to calculate original oil-in-place. 1) The hydrocarbon and water production from all wells producing from a often allows an accurate estimation of initial hydrocarbons in place and/or the The development of the general oil material balance equation can be found in any. [EQUATION]. where. ER = overall recovery (fraction of initial oil in place recovered) ED = displacement efficiency or volume of oil displaced divided by total oil 25 Sep 2019 The developed ANNs-based equation outperformed the available equations where STOIIP is the stock-tank oil initially in place at the original 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.
