Abstract
An improved method for management of by-products from subterranean zones, 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.
Claims28
A method for management of subterranean by-product, comprising:
- drilling a first well system into a subterranean zone, wherein the first well system comprises a first drainage pattern;
- removing via the first well system by-product from a first volume of the subterranean zone;
- producing gas from the first volume of the subterranean zone;
- drilling a second well system into the subterranean zone, wherein the second well system comprises a second drainage pattern;
- forming a subsurface hydraulic connection between the first drainage pattern and the second drainage pattern;
- moving by-product from a second volume of the subterranean zone to the first volume of the subterranean zone;
- and
- producing gas from the second volume of the subterranean zone.
A method for management of subterranean by-product, comprising:
- drilling a first well system into a subterranean zone, the subterranean zone having a structural dip, wherein the first well system comprises a first substantially dip-parallel drainage pattern extending updip in the subterranean zone and ending at a first terminus;
- removing via the first well system by-product from a first volume of the subterranean zone to allow gas production from the first volume;
- producing gas from the first volume via the first well system;
- drilling a second well system into the subterranean zone, wherein the second well system comprises a second substantially dip-parallel drainage pattern extending updip in the subterranean zone and updip of the first terminus and ending at a second terminus;
- and
- moving via the first well system and the second well system by-product from a second volume of the subterranean zone to the first volume of the subterranean zone;
- and
- producing gas from the second volume of the subterranean zone via the second well system.
