Abstract
An apparatus and method for hydrocarbon recovery in a well for coal bed methane (CBM) recovery, tight sand gas extraction, and other gas extraction techniques provides for the formation of a hydrocarbon foam comprised of a fluid delivered into a downhole portion of the well and the hydrocarbon, maximizing water removal for gas recovery. The apparatus may include a check valve that feeds a nozzle to deliver or atomize the spray of fluid into the downhole portion of the well when the pressure applied to the fluid is sufficient to overcome a hydrostatic pressure in the downhole portion of the well and to deliver the fluid into the downhole portion of the well. The fluid is not sprayed directly into the formation, thereby protecting the formation from damage and recovering the fluid even in the case where water is not present. The capillary tube feeding the fluid to the check valve may be placed externally to the production tube to facilitate ease of cleaning and clearing of the production tube.
