Fluid injection in light tight oil reservoirs

摘要

A method of producing hydrocarbons from a tight formation includes injecting a fluid, such as a miscible gas, and retrieving the hydrocarbons. The fluid may be injected into an injection fracture via and retrieved from a recovery fracture. The injection fracture and recovery fractures may be in the same wellbore, the injection fracture may be in a first wellbore and the recovery fracture in a second wellbore, or the injection fracture and recovery fracture may be in a first wellbore and additional injection or recovery fractures may be in a second wellbore.
