Abstract: 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.

Abstract: A conversion kit creates a redundant hydraulic, pneumatic, or mechanical control functionality for low-torque, quarter-turn plug valves in remote production environments (i.e., rural or subsea pipelines). The conversion kit comprises at least one custom end cap fitted to the valve and comprising a socket receiving a rotator attachment. Each rotator attachment is in turn connected to a crossover which connects to a bracket remotely actuated via hydraulic, pneumatic, or mechanical control. The linear movement of the bracket and the attached crossover[s] is converted to rotational force which is transmitted through the rotator attachments to the at least one valve.

Abstract: A non-electric explosive device includes a primary body containing cutting material and including a primary charge positioned in the cutting material; an explosive body at a first axial end of the primary body and including explosive material; and a firing head at a second axial end of the primary body, the firing head including a firing pin secured at least partially inside the firing head via securing device, the firing pin comprising an activating end proximate the primary charge and a blunt end protruding from a distal end of the firing head. A force applied to the blunt end of the firing pin causes the firing pin to retract toward the primary charge and break the securing device so that the activating end of the retracting firing pin impacts the primary charge which ignites the explosive material that causes the cutting material in the primary body to travel radially outward.
