Original oil in place equation
Material-balance equations provide a relationship between original fluids in place, cumulative fluid production, and average reservoir pressure. For many gas reservoirs, a simple material-balance equation can be derived on the basis of the following assumptions: Gas-filled pore volume is constant Original gas in place (OGIP) is again the same volumetric calculation but for natural gas reservoirs. Finally, hydrocarbons initially in place (HCIIP) is the generic term that can be used for both oil and gas when doing a volumetric calculation to estimate the contents of a potential drill site. 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. 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. Using the output of the block by block analysis, it was calculated that the 50 percent probability (P50) oil in place volume is 127 106m3. The block by block deterministic and probabilistic total oil in place for the South Avalon Pool is compared in Table 5.1-1 and the probabilistic distributions for the OOIP of the 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 The volumetric equations for original oil and gas in place were given earlier. In this section, volumetric equations will be given for the recovery of gas and oil reservoirs under several common instances. 5.5.7.1 Recovery of Gas. The volume of gas recovered, G p in scf, from a dry-gas reservoir is:
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
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. 27 Sep 2018 by Using Volumetric Method, Material Balance Equation. Method In the end, whether the calculation of initial hydrocarbon in place is made. 23 Mar 2015 Volumetric Estimation For OIL RESERVOIRS the oil initial in-place (OIIP) volumetric calculation is. •Metric: •OIIP (m3 ) = Rock Volume * Ø * (1- The Point estimate column shows the calculations based on best guess The second tab shows a tornado plot for the initial oil in place estimate, listing the Abbreviation for stock-tank oil initially in place, the volume of oil in a reservoir prior to production. Alternate Form: stock-tank oil initially in place, stock-tank original Original hydrocarbon-in-place resources were determined using a volumetric Free hydrocarbon-in-place was determined using Equations 2 through 7. such as porosity, hydrocarbon saturation, TOC (total organic content), gas content, thermal rock estimate of oil in place (OOIP) of 51 637 Bls/acre, gas adsorbed in place 39.72 The equations of Total water saturation from Aristobulo B. are:.

In this section, volumetric equations will be given for the recovery of gas and oil reservoirs under several common instances. 5.5.7.1 Recovery of Gas. The volume of gas recovered, G p in scf, from a dry-gas reservoir is: 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 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).. HCIIP a function of the Gross Rock volume (GRV) multiplied by the Net to Gross (NTG), Porosity (POR) and Oil or Gas Saturation (Shc).
