WebJun 22, 2024 · The image above represents gas initially in place. To compute for gas initially in place, five essential parameters are needed and these parameters are drainage area (A), initial gas FVF (Bgi), initial water saturation (Swi), porosity (φ) and thickness (h). The formula for calculating gas initially in place: G = 43560Ah φ (1 - Swi) / WebThis allowed a 2-point Material Balance calculation to be performed, which yielded an Original Gas-in-Place (OGIP) of 285 BCF (Figure 2). Most material balance calculations contain numerous data points, but only two were available in this case. The quality of the resulting calculation of OGIP could not be substantiated by additional points.
