Abstract
Methods and equipment are provided for stimulating recovery of hydrocarbons from a subterranean formation traversed by a wellbore, which employ at least one self-resonating nozzle. Fluid under pressure is supplied to the at least one self-resonating nozzle to create a channel in a surface of the subterranean formation facing the at least one self-resonating nozzle. In embodiments, the equipment can be a downhole tool or completion equipment (such as a liner) that is deployed in the wellbore.
Claims29
A method for stimulating recovery of hydrocarbons from a subterranean formation traversed by a wellbore, comprising:
- deploying equipment in the wellbore, wherein the equipment includes at least one self-resonating nozzle;
- and
- supplying fluid under pressure to the at least one self-resonating nozzle to create a channel in a surface of the subterranean formation facing the at least one self-resonating nozzle,
- wherein the fluid comprises a chemical composition that dissolves the subterranean formation.
Equipment that is deployable in a wellbore that traverses a subterranean formation, the equipment for stimulating recovery of hydrocarbons from the subterranean formation, the equipment comprising:
- at least one self-resonating nozzle configured to receive fluid under pressure and create a channel in a surface of the subterranean formation facing the at least one self-resonating nozzle wherein the fluid comprises a chemical composition that dissolves the subterranean formation.
A method for stimulating recovery of hydrocarbons from a subterranean formation traversed by a wellbore, comprising:
- deploying equipment in the wellbore, wherein the equipment includes at least one self-resonating nozzle;
- supplying fluid under pressure to the at least one self-resonating nozzle to create a channel in a surface of the subterranean formation facing the at least one self-resonating nozzle;
- and
- performing a fracture stimulation treatment after creation of the channel, wherein the fracture stimulation treatment injects fluid under high pressure into the formation to break formation rock and create fractures in the rock that are fluidly coupled to the wellbore, wherein the fractures initiate and propagate from the channel.
