Calculations to determine reserve values

There are two primary ways to determine reserve quantities: the volumetric method and decline curve analysis. The volumetric method This calculation is derived from the formulae – Gas-in-Place = 43,560 * A * H * f * Sg * Bg Reserves = (Recovery Factor) * (Gas-in-Place) This method may appear to be fairly ironclad until […]
