5.2: Estimation of Original Gas In-Place, OGIP, Using the Volumetric Method to the thickness that contributes to hydrocarbon storage and flow in the reservoir.

The simplest method to determine the quantity of original oil and gas in place in conventional reservoirs is volumetric analysis. First, the bulk volume of the reservoir is determined by knowing the reservoir boundaries and formation thickness. Next, the pore volume is determined based on rock porosity. Subsequently, the hydrocarbon pore volume (HCPV) is estimated when the saturation of fluids in the porous network is known. Finally, knowledge of formation volume factor of oil and gas is The deterministic estimation of oil in place for the White Rose Field was completed using 3-D geological modelling in the “RMS” software package. This procedure involves bringing structural surfaces in from the geophysical package (Landmark), building a detailed fault model, and then modelling both facies 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. Oil initially in place (OIIP) is the first estimate of the size of deposit prior to any production.

Accurate analysis for the water content is usually more difficult than the determination of gross volume, temperature, and gravity of the oil. Keywords: - oil, water, 

4D seismic has the potential to monitor hydrocarbon movement in reservoirs to estimate the volume of oil in place in each reservoir cell using seismic data  8 Mar 2019 Eni for the preparation of its proved reserves estimates as of December 31, 2018, When applicable, the volumetric method was used to estimate the original oil in place (OOIP) and the original gas in place (OGIP). Structure  Estimate initial oil in place: • Volumetric method (Monte Carlo Simulation). • Decline curve analysis. • Material balance equation. • Compare the results from the  11 Nov 2013 Usually a net oil sand (NOS) map will be prepared by the production geologist and then used to evaluate the hydrocarbon volume in place. Accurate analysis for the water content is usually more difficult than the determination of gross volume, temperature, and gravity of the oil. Keywords: - oil, water,  27 Sep 2005 A method of evaluating the volume ratio of gas to oil (GOR) in the of the liquid hydrocarbon at the surface (generally estimated at 0.8), ρr is  Volumetric estimates of OOIP original oil in place and OGIP original gas in place are based on a geological model that geometrically describes the volume of hydrocarbons in the reservoir. However, due mainly to gas evolving from the oil as pressure and temperature are decreased, oil at the surface occupies less space than it does in the subsurface. Conversely, gas at the surface occupies more space than it does in the subsurface because of expansion. This necessitates correcting subsurface
