A well head attachment is provided having an elongated casing or housing structure in which the tool string, including the entire cable or wire line supply, is pressurized, the housing structure being arranged to place the interior thereof in communication with the well bore in a manner whereby well pressure is equalized throughout the assembly during all operations, utilizing a unique pressure-tight adjustably articulated riser assembly with off-set pivotal radial connections for connection between the wellhead attachment and the pressurized cable-supply reel, thus the need for lengthy sinker weights, lubricators and stuffing boxes is reduced or eliminated.

Pressurized wire line spool and method for using same in conjunction with a universal radial carrier

A relatively light weight wire-line conveyance mechanism capable of sustained high pressure incorporated into a wire-line riser set-up and configured to allow multiple radial bends without sheaves. The conveyance mechanism includes a tubular body structure capable of being pressurized defining a radial arc of between 0 and 180 degree having a threaded coupling at each end for connection to riser tubular joints. One embodiment discloses a field formable cable conveyor that may take a variety of shapes. The tubular body contains a series of connected tubular blocks or sleeves, each of which includes a longitudinal bore and a roller or ball bearing assembly therein defining a wire-line pathway for receiving a wire-line that passes through each of said tubular blocks, fully contained therein.

Enclosed radial wire-line cable conveying method and apparatus

A relatively light weight radial wire-line conveyance mechanism capable of sustained high pressure incorporated into a wire-line riser set-up and configured to allow multiple radial bends without sheaves. The conveyance mechanism includes a segmented tubular body structure capable of being pressurized and defining a radial arc of between 0 and 180 degree having a threaded coupling at each end for connection to riser tubular joints. The tubular body contains a series of connected tubular segments, each of which includes a longitudinal bore and a roller or ball assembly therein defining a pressurized wire-line pathway for receiving wire-line that passes through each of the tubular segments.

A heavy duty, locked, tubular quick coupling used for coupling oil and gas well tubing or pipe joints, thus allowing long strings of pipe and tube joints subsequently connected to at least one such quick coupled joint to be lifted as a string, thereby applying tensile loading to the quick coupled joints. Both interior and exterior locking arrangements for the locked quick coupling are disclosed which utilize twist-locking elements secured in position by a locking washer and cap nut. Arrangements are also disclosed illustrating how the locking couplings are used for fast setup of wire-line riser strings utilizing multiple specialty subs and valve assemblies.

Method and apparatus for locking a tubular quick coupling

A quick-coupling union for oil and gas tubular members that provides a more stable joint connection, a redundant seal arrangement, and a method for pressure testing the seals. The union and sealing arrangement includes an elongated tubular receiving member, further including a central longitudinal cavity therein for receiving an elongated tubular insertion member and an external port in communication with the cavity, at least two sealing members located within the cavity defined by the insertion and receiving members and the dual seals being capable of providing a positive seal between the insertion member and the receiving member the union, further including a nut slidable upon the insertion member for threadably locking the insertion member relative to the receiving member, the sealing members being spaced apart in a manner whereby the external port is interposed between the dual sealing members when the union is fully engaged, thus defining a means for applying a pressure there upon.
