Volume of oil in place

4 Jan 2018 Original Oil-In-Place: Original Oil-in-place refers to the total volume of oil stored in a reservoir prior to production. Hydrocarbon Pore Volume In calculating the volume of the reservoir, accurate determinations of the areal extent Original Oil-in-Place (OOIP) Calculations where A = area, d = thickness, ϕ = porosity, Sw = water saturation, Sg = gas saturation, and B = oil formation volume factor (subscripts: i initial, a abandonment). oil in place (OOIP) based on surface area A and the structure thickness, (H) using the recovery factor, and the volume of Oil (1-Sw) and the type of fluid or gas . Estimation of in place hydrocarbon volume in multilayered reservoirs using In the following, a brief literature review, related to reservoir estimation in oil. 28 Sep 2017 e) If the reservoir contains 250MM reservoir barrels of oil initially, what is the initial number of STB in place? f) What is the initial volume of

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.

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 h = thickness of reservoir pay, ft Φ = porosity (decimal, not percent) 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). Original oil in place (OOIP) and original gas in place (OGIP) 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.

3. BASIC TERMINOLOGY. OOIP: Oil Initial in Place. GIIP: Gas Initial in Place. OWC: Oil Water Contact. GOC: Gas Oil Contact. IGCP: Initial Gas Cap Volume.

8 May 2015 carried out an assessment of the Stock Tank Oil Initially In Place (“STOIIP”) volumes. Xodus has independently reviewed the STOIIP volume 12 Sep 2014 Initially In-Place Volume (IIP): HCPV combined with formation volume factor. ( commonly abbreviated to Bo for oil or Bg for gas). For this project the volume uncertainty range are important input for risk mitigation actions such reservoir to a case where the oil leg is communicating through the entire 16 Sep 2010 A general formula for the calculation of the volume of hydrocarbons in a reservoir The hydrocarbon volumes of specific types of fluids (oil and/or gas) in the For marginal reservoirs, underestimation of in-place hydrocarbon 1 Mar 2003 the amount of “oil in place” can be revised upwards, because the volume of the reservoir rock is deemed to be more important than initially water density is 8.3 pounds per gallon), and a meter measures the volume of gas original oil in place – The volume of oil originally in place in a reservoir.

(1 ¸ B o) gives the shrinkage, the volume change in the oil as it comes to the surface. One of the problems with the method are the approximations used, these can lead to poor estimations. Recoverable Oil Volume. Of perhaps more importance than OOIP — is the recoverable oil volume. This is found by multiplying the OOIP by a recovery factor.

10 Aug 2017 Hence, constant reservoir volume and water saturation, Sw were used to calculate the original oil in place (OOIP). Therefore, this paper focused b) What is the reservoir volume of oil? c) What is the initial stock-tank-barrels of oil-in-place? d) How many scf of dissolved gas are in the reservoir

1 Mar 2003 the amount of “oil in place” can be revised upwards, because the volume of the reservoir rock is deemed to be more important than initially

Stock tank oil initially in place (STOIIP) is the same volumetric calculation with it being made explicit that the volume being estimated is the volume filled by the extracted oil at surface temperature and pressure rather than the compressed volume the crude oil fills in the reservoir due to geological pressure. 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 w(t) = water saturation at time t, fraction B o(p(t)) = oil formation volume factor at reservoir pressure p, bbl/STB 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.

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)
