Subsurface well systems with multiple drain wells extending from production well and methods for use thereof

摘要

Drain wells can be used to direct a fluid to a central production well in a subsurface well system. Subsurface well systems can include a production well extending from the earth's surface, a collection region having a fluid connection to the production well and either being contiguous with the production well or comprising a collection well that intersects or is in fluid communication with the production well, and at least one branched drain well extending laterally from the production well and including one or more branches that extend from the at least one branched drain well, wherein at least one of the one or more branches intersects or is in fluid communication with the collection region.
