PROCESS AND WELL ARRANGEMENT FOR HYDROCARBON RECOVERY FROM BYPASSED PAY OR A REGION NEAR THE RESERVOIR BASE

摘要

Hydrocarbons may be produced from a well which comprises a contour section that follows a contour of a depression on a contoured base above which the reservoir is formed. Hydrocarbons may also be produced from a first well in a gravity-controlled recovery process and a second well which extends under and across the first well. For recovery of hydrocarbons from a reservoir, a pair of injection and production wells may be positioned and configured to optimize an initial rate of production from a pay region in the reservoir, and another well for producing hydrocarbons may be located below the production well and be positioned and configured to optimize an amount of hydrocarbon recovery from the pay region.
