Question 13 - 15 marks A dry gas has a specific gravity of 0.648 at reservoir temperature of 185°F and reservoir pressure of 2562 psia. Evaluate: a) OGIP, given that the gas reservoir has an area 170 acres, a uniform thickness of 15 ft, a porosity of 26% and a connate water saturation of 22%. (9 marks) 4 b) Recoverable and Remaining reserves with a recovery factor of 48%.
