1. A well system, comprising;
- a first well bore extending from a surface to a subterranean zone;
a second well bore extending from the surface to the subterranean zone;
a first articulated well bore formed off of the first well bore, the first articulated well bore intersecting and extending through the second well bore and coupled to a first pattern formed in the subterranean zone through the first articulated well bore;
a second articulated well bore formed off of the second well bore, the second articulated well bore intersecting and extending through the first well bore and coupled to a second pattern formed in the subterranean zone through the second articulated well bore;
the first pattern operable to transport fluids from the subterranean zone to the second well for production to the surface; and
the second pattern operable to transport fluids from the subterranean zone to the first well for production to the surface.

Abstract
A well system includes at least two well bores extending from a surface to a subterranean zone. Each of the two well bores is used to form a well bore pattern for the subterranean zone that intersects the other well bore and transports fluid from the subterranean zone to the other well bore for production to the surface. In addition, each of the two well bores is operable to collect fluids transported to the well bore by the well bore pattern formed through the other well bore for production to the surface.

12. A well system, comprising:
-
at least two well bores extending from a surface to a subterranean zone; each of the two well bores being used to form a substantially horizontal well bore pattern for the subterranean zone that intersects the other well bore and extends beyond the other well bore and transports fluid from the subterranean zone to the other well bore for production to the surface; and each of the two well bores operable to collect for production to the surface fluids transported to the well bore by the substantially horizontal well bore pattern formed through the other well bore. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for forming a well system, comprising:
-
forming a first well bore extending from a surface to a subterranean zone; forming a second well bore extending from the surface to the subterranean zone; kicking off the first well bore above the subterranean zone to form a first subterranean pattern in the subterranean zone, the first subterranean pattern coupled to the second well bore and operable to transport fluids from the subterranean zone to the second well bore for production to the surface through the second well bore; and kicking off the second well bore above the subterranean formation to form a second subterranean pattern in the subterranean formation, the second subterranean pattern coupled to the first well bore, located on an opposite side of the first well bore from the first subterranean pattern, and operable to transport fluids from the subterranean zone to the first well bore for production to the surface through the first well bore. - View Dependent Claims (19, 20)

21. A method for forming a well system, comprising:
-
forming a first well bore having a cavity proximate to a subterranean zone; forming a second well bore having a cavity proximate to the subterranean zone; kicking off the first well bore above the subterranean zone to form a first pattern in the subterranean zone, the first pattern intersecting the cavity of the second well bore and operable to transport fluids from the subterranean zone to the cavity of the second well bore for production to the surface through the second well bore; and kicking off the second well bore above the subterranean formation to form a second pattern in the subterranean formation, the second pattern intersecting the cavity of the first well bore and operable to transport fluids from the subterranean zone to the first well bore for production to the surface through the first well bore. - View Dependent Claims (22)
