Abstract
A method and system for enhancing permeability of a subterranean zone at a horizontal well bore includes determining a drilling profile for the horizontal well bore. At least one characteristic of the drilling profile is selected to aid in stabilizing the horizontal well bore during drilling. A liner is inserted into the horizontal well bore. The well bore is collapsed to increase permeability of the subterranean zone at the horizontal well bore.
Claims21
A method for enhancing permeability of a subterranean zone at a well bore, comprising:
- determining a drilling profile for drilling a horizontal well bore in a subterranean zone, at least one characteristic of the drilling profile selected to aid in stabilizing the horizontal well bore during drilling;
- inserting a liner into the horizontal well bore;
- and
- collapsing the horizontal well bore.
11-13. (canceled)
A method for obtaining resources from a coal seam, comprising:
- forming an articulated well bore having a substantially horizontal portion formed in the coal seam, the coal seam disposed proximate at least one aquifer;
- and
- enhancing production of resources from the coal seam into the well bore without hydraulically fracturing the coal seam.
A method for producing gas from a coal seam, comprising:
- drilling a horizontal well bore in a subterranean zone, the well bore sized to collapse in response to a down-hole pressure condition;
- maintaining down-hole pressure in the well bore above the down-hole pressure condition during drilling;
- and
- reducing the down-hole pressure to the down-hole pressure condition to purposefully collapse the well bore.
A system for producing gas from a subterranean zone, comprising:
- a well bore including a horizontal portion in the subterranean zone, the subterranean zone proximate at least one aquifer;
- a liner in the horizontal portion;
- and
- a plurality of apertures in the liner.
