ABSTRACT:
A method for recovering fluids such as crude oil, associated solution gas, formation water, injected water, natural gas and other gases, and natural gas liquids, from a hydrocarbon producing reservoir or formation in which fluids collected in one or more substantially horizontal wells are routed to the surface through a substantially vertical wellbore. The method may be employed in connection with entirely new well systems, by drilling a vertical wellbore to intersect or penetrate the producing formation in close proximity to one or more existing horizontal wells, or by drilling one or more horizontal wells to intersect or terminate in close proximity of an existing vertical wellbore. Preferably, the vertical wellbore extends to a depth greater than the depth of intersection with the horizontal well or wells, forming a sump for the collection of fluids.
