Abstract: A downhole tool for transmitting rotation to a casing string includes a tool body having a bore extending from a first end to a second end. The downhole tool also includes a cam positioned within the tool body, the cam being axially translatable along an axis of the bore. The downhole tool further includes a recess, formed in an outer diameter of the cam. The downhole tool includes a locking mechanism, positioned at least partially within the tool body. The locking mechanism includes a tool key. The locking mechanism also includes a biasing member, the biasing member driving the tool key toward the retracted position.

Abstract: An adapter for connecting a casing annulus remediation system to a well having a wellhead with standard lateral ports. The adapter has a body with first and second ends. The first end of the adapter body has a substantially planar surface adapted to cover the lateral ports and be in abutting contact with the wellhead when the two are connected to one another. The second end of the adapter body has a planar surface positioned at an angle greater than 0 degrees and up to 90 degrees to the planar surface of the first end. The second end of the adapter is adapted to be connected to a casing annulus remediation system.

Abstract: A thermal wellhead having a high voltage cable for in-situ upgrading and processing unconventional oil reservoirs is disclosed. An electrical cable has a power umbilical with an electrical heater on a lower end and an electrical connector opposite the heater. An upper portion of the cable has a second electrical connector for connection with the first connector and is connected to a transformer. A well control device is installed at the wellhead and the umbilical is extended through the device in the well. The first connector is landed in the wellhead such that the umbilical extends downward through the well. The well control device is then removed from the wellhead, and the second connector is secured in a tubing bonnet. The bonnet is landed on the wellhead to make electrical connections between the connectors.

Abstract: An apparatus for insertion into a well to displace well fluid. A flexible hose is lowered into an annulus between strings of casing. A nozzle is affixed to the lower end of the hose. During insertion, the hose is pressurized and rigid to keep the hose from winding about the well. To keep the hose rigid, internal pressure is maintained in the hose. The nozzle is provided with a check valve that holds the internal pressure up to a selected amount. Once the hose is lowered to a desired depth, the operator increases the pressure sufficiently in the hose to open the check valve, thereby allowing heavy liquid to flow out. The heavy liquid displaces the lighter well production, which flows out of the outlet. After the heavy fluid has been dispensed, the internal pressure is reduced, causing the check valve to close. The check valve can also be opened during insertion, if desired.

Abstract: A drilling head used to seal around a drill pipe while drilling is employed in a subsea location. The drilling head has an inner body located within an outer body. At least one bearing is located between the outer body and the inner body for facilitating the rotation of the inner body relative to the outer body. A seal mounted to a lower portion of the inner body seals around the outer surface of the drill pipe. While lowering the drilling head to the wellhead, a support attached to the drill pipe is inserted into a skirt which surrounds a portion of the seal. The skirt and support are releasably connected using a J-slot mechanism. An inner annulus and an outer annulus are located between the inner and outer bodies, the annuluses containing a lubricating fluid. Helical vanes are located within the inner annulus and affixed to the inner body. The vanes rotate with the inner body for circulating the fluid through the inner and outer annuluses.

Abstract: A casing annulus remediation system for lowering a flexible hose into an annulus between strings of casing in a petroleum well by pressurizing the hose so that the hose is rigid and may be forced down the annulus. It is necessary to insert the hose through an outlet into the annulus region for well fluid displacement when pressure builds up in the annulus between casing strings due to leaks in the casing. Pressure build-up in the annulus is reduced by pumping a heavy liquid, sealant or other media through the hose into the annular space experiencing the pressure build-up. A tubing nose is affixed to the lower end of the hose. The hose may be inserted hundreds of feet into the well. Therefore, the hose is pressurized to maintain rigidity to keep the hose from winding about the well during deployment. To keep the hose rigid, internal pressure is maintained in the hose. The tubing nose is provided with a check valve that holds the pressure.

Abstract: Two or more opposing and outward facing profiles are fabricated and joined to each other along their outer edges, forming a section of a guide string. The sections of the guide string are secured together in an assembly and lowered into a single conductor. The assembly lands on the bottom of the well and may support its own weight. The guide string defines two separate longitudinal cavities or sections of the well. Each separate cavity allows drilling and installation of casing in the conductor.

Abstract: A coiled tubing completion system has a gripping mechanism on a lower end which land in a tubing hanger and engage coiled tubing extending through the tubing hanger. A tubular member is located above the gripping member and receives the upper end of the tubing. A tapered metal seal seals between the tubular member and the coiled tubing. A threaded nut, when rotated, causes the seal to energize.

Abstract: A casing annulus remediation system for overcoming problems associated with lowering a flexible hose into an annulus between strings of casing in a petroleum well by pressurizing the hose so that the hose is rigid and may be forced down the annulus. It is necessary to insert the hose through an outlet into the annulus region for brine displacement when pressure builds up in the annulus between casing strings due to leaks in the casing. Pressure build-up in the annulus is reduced by pumping a heavy liquid through the hose into the annular space experiencing the pressure build-up. A nozzle is affixed to the lower end of the hose. The hose may be inserted several hundred feet into the well. Therefore, the hose is pressurized to maintain rigidity to keep the hose from winding about the well during deployment. To keep the hose rigid, internal pressure is maintained in the hose. The nozzle is provided with a burst disk that holds the pressure.
