Gas initially in place

From Wikipedia, the free encyclopedia

Gas initially in place (GIIP) or original gas in place (OGIP) denote the total estimated quantity (volume) of natural gas contained in a "subsurface" asset prior to extraction (production).[1]

Gas Initially In Place = Gross Rock Volume * Net/Gross * Porosity * average initial Gas Saturation / Formation Volume Factor[2]
