Effect of Fracture Spacing on Gravity Drainage for Various Kmatrix / Kfracture Ratio

P10 EFFECT OF FRACTURE SPACING ON GRAVITY DRAINAGE FOR VARIOUS KM/KF RATIO 1 Abstract Most of the reservoirs in the Islamic Republic of Iran are naturally fractured. This is essentially a by-product of the stress folding and heavy faulting that is caused by the tectonic movements of the Zagaros Mountains. Fracturing therefore plays a critical role in reservoir production and in the ultimate hydrocarbon recovery. Recent studies show that 1-D simulation of gravity drainage leads to large errors when the matrix aspect ratio is larger than 2.5. The objectives of this paper is at first deriving the fracture spacing using
