摘要： A wash tool comprises a mandrel with a central annulus and one or more lateral bores and one or more ring-shaped rotary hubs positioned about the mandrel adjacent to the one or more lateral bores. The rotary hubs comprise lateral bores perpendicular to the lateral bores of the mandrel such that pressurized fluid introduced to the central annulus of the mandrel impacts the inner surface of the rotary hubs and forces them to rotate, delivering pressurized fluid to the inner surface of a wellbore or tubular. The wash tool is modular and can be attached to a top sub or bottom sub, and may be used with or without a wireline. When used with a wireline, the wireline is insulated from the wash fluid by means of a tie-back and multiple seals.

摘要： Explosive cutter assemblies and methods include a liner having a single unitary body, and an explosive charge disposed within the liner. The explosive charge includes a continuous unitary body of explosive material having a first area disposed in association with an inner surface of the liner and a second area extending from the center of the assembly to the first area. A detonator can be used to ignite the second area of explosive material, causing propagation of a detonation to the first area, which in turn causes deformation of the liner and projection of the liner toward a target to form a cut. An adaptor sub having a detonator within can be inserted into the cutter assembly to secure the assembly together, position the detonator in association with the explosive material, and engage a conduit usable to raise and lower the cutter assembly and transmit a detonation signal.

摘要： The present application is directed to a submersible pumping system operable under hydrostatic pressure. The system suitably comprises a prime mover submersible within a first fluid; a pump means submersible within the first fluid and sealably coupled to the prime mover; and a fluid source in fluid communication with the prime mover, the fluid source providing a second fluid effective to act on the prime mover to power the pump means; wherein the second fluid is discharged in the first fluid after acting on the prime mover; and wherein the second fluid has a chemical composition substantially similar to the first fluid.
