METHODS, SYSTEMS, AND APPARATUS FOR PRODUCTION OF HYDROCARBONS FROM A SUBTERRANEAN FORMATION

摘要

Methods, systems, and apparatus that are suitable for use in production of hydrocarbons from subterranean heavy oil deposits employ a subterranean cavity in communication with a borehole. The cavity is preferably formed along a U-tube borehole by coiled tubing reaming operations and/or radial drilling and explosive blasting.
