A method and apparatus for preventing fluid flow and contamination to a cement body includes a resin cap covering an exposed end of the cement body. The cement body may attach an inner sleeve to an outer sleeve. The fluid flowing through the outer sleeve is prevented from contacting the exposed surface by the resin cap. Resin caps at both ends of the cement body along with resin layers along the side may be included. The resin prevents contamination and creation of micro-annuli in the cement body.

A self-retracting coiled cable having a variable length along a center line can include an outer insulator sleeve having a longitudinal axis. The self-retracting coiled cable can also include a spring material extending along the longitudinal axis of the outer insulator sleeve. The spring material can hold the outer insulator sleeve in a helical shape around the center line. The spring material can also allow the self-retracting coiled cable to expand upon an application of an axial force to an end of the self-retracting coiled cable, thereby increasing a length of the self-retracting coiled cable, and to retract upon a removal of the axial force from the end of the self-retracting coiled cable, thereby reducing the length of the self-retracting coiled cable. The self-retracting coiled cable can further include multiple wires extending along the longitudinal axis of the outer insulator sleeve and disposed symmetrically around the spring material.

A single use setting tool and associated method for actuating a tool in a wellbore may include an inner piston with an annular wall defining a piston cavity. A portion of the inner piston including the piston cavity may be positioned within a central bore of an outer sleeve, and the inner piston and the outer sleeve may be slidable relative to one another. A portion of the inner piston may extend beyond an end of the outer sleeve and have a shock absorbing wedge positioned thereon, and the end of the outer sleeve may have a cutout for receiving the shock absorbing wedge. A bi-directional gas-generating power charge may be positioned in the piston cavity and include a power charge having a booster positioned in an indentation adjacent each of a first end and a second end of the power charge.

An opposed ramp assembly is configured with a load bearing lug. The lug has angled ends that match the opposed profile shapes that rotate as the lug reciprocates with each piston stroke. One side of the opposed profiles of the opposed ramp pattern has no axial travel grooves for the lug. On the other side there can be one or more open slots for the lug to facilitate assembly and disassembly of the lug to the operating location or to accommodate one or more needed positions for the tool depending on the application. As a result the opposed pattern peaks have increased spacing for the same stroke length of the piston. This allows for more reaction time in a partial stroke to avoid jamming because the potential position for jamming is far later so that reversal of movement can occur without jamming, if it occurs in the early part of the stroke. Peak to peak axial separation of the opposed pattern profiles is increased by a factor of at least 24.

A downhole control device is configured to activate downhole equipment requiring control signals. The device having a housing adapted to protect electronic components; a transducer configured to measure one or more of pressure and temperature; an accelerometer; and control circuitry in communication with the transducer and the accelerometer and configured to control the operation of a downhole tool depending on data from one or more of the transducer and accelerometer. The transducer, the accelerometer and at least part of the control circuitry are mounted on a chassis that is removably inserted within the housing.

A flow management system includes an adjustable compactor configured for attachment to a wall surface of a conduit and being adjustable between an extended configuration and a reference configuration, an electric actuator in fluid communication with the adjustable compactor, and a control module. The control module is configured to control the electric actuator to flow a current to the adjustable compactor to generate an electric field that causes extension of the adjustable compactor for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to remove the electric field at the adjustable compactor to cause the adjustable compactor to return to the reference configuration for opening the channel to a fluid flow within the conduit.

Apparatuses and methods for operating a downhole tool are disclosed. A downhole tool configuration device includes an upper stem movable between an up position and a down position. The upper stem comprises an extended portion. An outer sleeve is selectively coupleable to the upper stem at the up position and the down position and an inner sleeve is selectively coupleable to the upper stem at the up position and the down position. In the up position, the upper stem is operable to transfer tension to the outer sleeve and torque to the inner sleeve. In the down position, the upper stem is operable to transfer torque to the outer sleeve.

A multi-perforating assembly can include a housing containing a rotor. The rotor can be axially stroked by a multi-stroker tool. Upon axial movement, the rotor can cooperate with the housing to incrementally rotate. Axial movement of the rotor can cause a multi-perforating cartridge to radially pierce. Rotation of the rotor combined with piercing of the multi-perforating cartridge can enable multiple piercings to be easily and quickly performed in a single run. A multi-perforating cartridge can include a blade pivotally attached to a slider. The blade can be pulled past ports in a cartridge housing whereupon biasing springs can push the blade into the ports and a support pin can push the blade into piercing positions before pushing the blade into transitional positions, after which the blade can be biased into the subsequent port.
