... Abstract The Khasib limestone holds over 60% of the oil reserves in the Ah oil field in Iraq. During production, water has been observed flowing from the structural high while oil is produced from the flank area, a phenomenon that cannot be explained by a simple tilted oil-water contact (OWC...

... was confirmed by well RF-B10 in 2004. This well encountered the original field oil-water contact at 2450' TVDss despite 20 years production in the main field. The oil-water contact is thought to be in part influenced by secondary gas cap expansion which has "pushed" the oil column back to the original spill...

... to depleted reservoir pressure and low permeability. In 2012, reservoir modeling using a geostatistical approach created 21 realizations to cover uncertainty in facies distribution, porosity, permeability and oil-water contact. We adopted three models to represent the P10, P50 and P90 cases. The three models...

... compartmentalization. • An early charge of oil in the Arab D was partially displaced later by gas. • Oil-filled inclusions are present well below the estimated original oil-water contacts (OOWCs), and suggest trap modification after oil migration, or the active migration of oil through these strata...

... oil reservoirs are the Upper Jurassic Arab C and Arab D. There are lesser amounts of oil and gas in the Middle Jurassic and non-associated gas in the Permo-Triassic Khuff formation. PVT measurement Upstream Oil & Gas depletion concentration gas-oil contact oil-water contact...

... Abstract Optimal field development often entails placing the wells in prescribed locations within the reservoir. An error of a few meters in height above the oil-water contact or with respect to the roof can result in millions of barrels left behind through the life of the field. Driven...

However, this poor coverage does not provide adequate information for the field that is of the size of Greater Burgan, Some additional information is available from the oil-water contacts based on open-hole logs taken in the new...
