SYSTEM AND METHOD FOR PRODUCING FLUIDS FROM A SUBTERRANEAN FORMATION

摘要

The system of subterranean wells includes a subsurface flow line (20) having at least a portion within or underlining one or more subterranean formations (12). One or more drainage wells (26, 28, 30, 32, and 34) each extend from the surface and intercept at least one of the subterranean formations at a respective interception location. A lower portion of each drainage well is in fluid communication with the subsurface flow line. A recovery well (42) extends from the surface and is also in fluid communication with the subsurface flow line, so that fluids entering the drainage well flow into the subsurface flow line and then into the recovery well.
