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. Petroleum calculator solving for oil recovery factor given estimate of recoverable oil and estimate of in place oil Math Geometry Physics Force Fluid Mechanics Finance Loan Calculator. Oil Recovery Factor Equations Formulas Calculator Energy Petroleum Gasoline Petrol Gas. Solving for oil recovery factor. Inputs: estimate of recoverable oil This may be counter-intuitive. However, this is a result of the evolution of gas from oil as pressure decreases from reservoir pressure to surface pressure. If an oil had no gas in solution (i.e., a dead oil), the volume that it would occupy at reservoir conditions is less than the volume that it occupies at the surface. In this case, only
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,
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.

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.
First we have the initial oil in place (OIP), that is, the amount prior to any exploitation which is to be found in undiscovered and discovered fields. Obviously, the OIP is difficult to estimate. As for the undiscovered (unknown) fields, an estimate has to be made based on the discovered (known) fields in relation to the geologic setting. 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 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. As this quantity cannot be measured directly, it has to be estimated from other parameters measured prior to drilling or after production has begun. Stock-tank Oil Initially in Place (STOIIP) is the total amount of crude oil present in a hydrocarbon reservoir before the commencement of any production. As it is not possible to measure the total volume or exact quantity of the oil in the hydrocarbon reservoir, other parameters are considered and studied for any judgment of oil estimation. 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. OIL and gas in place anD reserves Calculating oil or gas in place from petrophysical analysis results is a simple matter of calculating volumes from reservoir thickness, porosity, and water saturation. The area of the reservoir is usually contoured from maps of the reservoir properties. Calculating oil volume in place. 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
The calculations follow the formulae: The second tab shows a tornado plot for the initial oil in place estimate, listing the input variables in descending order of
[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. First we have the initial oil in place (OIP), that is, the amount prior to any exploitation which is to be found in undiscovered and discovered fields. Obviously, the OIP is difficult to estimate. As for the undiscovered (unknown) fields, an estimate has to be made based on the discovered (known) fields in relation to the geologic setting.
