Title: (EN) Method of producing a communicating horizontal well network
Abstract: front page image
(EN)

A method of producing fluids from a subterranean formation through a single well in a network of separate well-bores, comprising the steps of: forming a well having a horizontal section located within the formation; completing and equipping such well to produce fluids from the formation; producing fluids from the formation through such well; forming at least one additional well having a horizontal section located within the formation such that such well is in fluid communication with the first well, without intersecting with the horizontal section of the first well, and using such additional well as an conduit within the formation to allow and cause fluids contained in the formation which drain or flow into the horizontal section of such additional well-bore, to flow to and be produced through the first well-bore.
