| titleOfInvention | Method for achieving communication between injection and production wells in tar sand deposits |
| abstract | Abstract of the Disclosure A method for achieving communication between an injection well and a production well in tar sand deposits. A cavity is excavated at a point where the injection well is proximate to the production well. A fluid is injected in the production well at a pressure less than fracture pressure to cause the subterranean formation intermediate the production well and the cavity to collapse and create a highly permeable zone of unconsolidated tar sands, thus forming a communication path between the production well and the injection well. In a preferred embodiment of the invention several injection vertical wells are used in combination with one associated horizontal production well. In this embodiment, a hydraulically balanced system may be established by selectively shutting-in the injection wells while maintaining fluid pressure in the production well. After the communication paths are created, field production operations may begin. Steam and other fluid may be injected in the injection wells to encourage gravity drainage of bitumen toward the production well. Bitumen is produced to the surface through the production well via any number of known artificial lift methods. |
