Abstract: A system for recovering a fluid from a subterranean formation, including a production wellbore having a substantially horizontal production length extending through the formation, and a trench extending through the formation. A method of constructing a trench section in a subterranean formation, including providing within the formation an access wellbore having a substantially horizontal access wellbore length, introducing a trench cutting tool into the access wellbore, and advancing and retracting the trench cutting tool through the access wellbore in order to cut slots in the formation in a trench direction away from the access wellbore, repeatedly until a number of slots required to complete the trench section has been cut.
