Method and system for enhanced access to a subterranean zone

A method for accessing an area of a subterranean zone from the surface, comprising:

• forming a first well bore extending from a surface well bore substantially defining a first end of the area in the subterranean zone to a distant end of the area;
• and
• forming a plurality of lateral well bores extending outwardly from the first well bore, wherein a distance from an end of a lateral well bore to the surface well bore is substantially equal for each of the lateral well bores.

A system for accessing a subterranean zone from the surface, comprising:

• a first well bore pattern extending from a surface well bore, the first well bore pattern forming a first substantially quadrilateral area;
• and
• a second well bore pattern extending from the surface well bore, the second well bore pattern forming a second substantially quadrilateral area, and wherein a first side of the first quadrilateral area is disposed substantially in common with a first side of the second quadrilateral area.

A method for accessing a subterranean zone from the surface, comprising:

• forming a first well bore pattern in the form of a first substantially quadrilateral area, the first well bore pattern extending from a surface well bore;
• and
• forming a second well bore pattern in the form of a second substantially quadrilateral area, the second well bore pattern extending from the surface well bore, and wherein a first side of the first quadrilateral area is disposed substantially in common with a first side of the second quadrilateral area.

A system for accessing a subterranean zone from the surface, comprising:

• a surface well bore extending from the surface to the subterranean zone;
• and
• a plurality of well bore patterns disposed within the subterranean zone each extending in a different direction from the surface well bore, the plurality of well bore patterns symmetrically disposed about the surface well bore.

A method for accessing a subterranean zone from the surface, comprising:

• forming a surface well bore extending from the surface to the subterranean zone;
• and
• forming a plurality of well bore patterns disposed within the subterranean zone each extending in a different direction from the surface well bore, the plurality of well bore patterns symmetrically disposed about the surface well bore.

A system for accessing a subterranean zone from the surface, comprising:

• a first well bore pattern disposed within the subterranean zone extending from a first surface well bore;
• and
• a second well bore pattern disposed within the subterranean zone extending from a second surface well bore, the first and second well bore patterns configured to nest adjacent each other within the subterranean zone.

A method for accessing a subterranean zone from the surface, comprising:

• forming a first well bore pattern extending from a first surface well bore and disposed within the subterranean zone;
• and
• forming a second well bore pattern extending from a second surface well bore and disposed within the subterranean zone, the first and second well bore patterns arranged to nest adjacent each other within the subterranean zone.
