Abstract

An improved method for management of by-products from subterranean zones, in particular for the dewatering of coal seams, comprising drilling a first well system into a subterranean zone, wherein the first well system comprises a first drainage pattern. By-product and gas from a first volume of the subterranean zone is removed via the first well system. A second well system is drilled into the subterranean zone, wherein the second well system comprises a second drainage pattern, and by-product is moved from a second volume of the subterranean zone to the first volume of the subterranean zone. Gas is then produced from the second volume of the subterranean zone. Subsequent drainage patterns repeat the process.
