STACK OSAGE RESERVOIR Woodford oil source Osage sits right on top of it Oil trapped in micro-darcy rock matrix top seal from Meramec and Chester ductile rock Oil saturation over whole Osage section with gas in solution no free gas…
STACK OSAGE GOR IS IMPORTANT You have to touch the matrix rock with a fracture to produce oil (i.e. break new rock). Oil wont move far or fast through micro-pore system from matrix to fracture - millimeters or few inches, per year…
