Abstract
The Akhen field comprises Serravallian-aged deep water sandstone reservoirs of the Sidi Salem Formation, located in the Ras El Bar Concession in the offshore Nile Delta. The sequence is composed of a 550 m thick stacked deep-marine slope turbidite gas-condensate reservoirs. Three depositional architectural elements are recognised: slope channels, proximal levees and distal levees. Each archtitectural element has a distinctive facies association which controls reservoir quality (permeability), ranging from <5mD in thin bedded proximal levee reservoirs to >1000mD in the axis of slope channels. To date the gas production has focuseed on depleting the amalgamated channel-sands. This paper investigates the nature and gas production potential of the deep water leveed thin bed pay.
