Abstract: Methods of gravel packing a subterranean well located subsea utilizing through-the-flowline techniques are disclosed in which a sand slurry is pumped downwardly through one pipe of a dual pipe string and outwardly through an H-type crossover member (14, 15) into a perforated casing area (20) until the area is fully packed. In one method, the H-type crossover member (14) is provided with a flangible plug (14h) to allow bypass of the sand slurry once the perforated casing area is filled with aggregate. In another method, the gravel packing of the perforated casing area is accomplished utilizing a special TFL tool (25) which provides for injection of the sand slurry through an H-type crossover member (15) into the perforated casing area (20).

Abstract: An apparatus and method is described for introducing and removing TFL tools from a subsea wellhead assembly. The apparatus includes an elongate member adapted to hold at least one TFL tool, docking hubs for aligning the elongate member with the wellhead, a clamping mechanism or the like for engaging the elongate member with the wellhead and a circulation for circulating fluid within the elongate member and the wellhead to transport the TFL tool between the elongate member and the wellhead. In another embodiment, the apparatus includes at least two elongate members and a diverter located between the elongate members and the clamping mechanism. The diverter permits alternate fluid communication between each elongate member and the wellhead assembly.

Abstract: A compliant pile system for supporting the vertical weight of a guyed tower structure installed in a body of water. The pile system is comprised of at least one pile element which in turn is comprised of a pile jacket and a pile member. The pile jacket extends from one point in the structure to a second point which lies above the first point and is attached at only one point to the structure. The pile member passes through the pile jacket and is forced into the marine bottom and is attached only at its upper end to the pile jacket. In one modification, the pile jacket is comprised of an odd number of concentrically positioned sleeves with the pile member being affixed to the top of the innermost sleeve and the outermost sleeve being affixed only at its bottom to the structure. The sleeves, if more than one, are attached to each other at their respective alternate ends.

Abstract: A self-locking cable connector especially useful in wireline data telemetry operations or wellbore logging comprises a plug and receptacle. A locking sleeve assembly acts to lock a key on the plug into a circumferential keyway on the receptacle, when the plug is inserted into the receptacle to form an electrical connection. Seals keep the connectors isolated from the drilling fluid which is circulated during rotary drilling. The cable connector may pass through rig sheaves and may be spooled with the cable.
