摘要： The invention relates to the introduction of pressurized fluid, e.g. acid, into a subsea well directly from a vessel (33). A fluid injection assembly (20) is fitted to the top of a subsea Xmas tree (3), the assembly (20) including fail safe closed valve (21) which is controlled via a hydraulic line (31) from the vessel. The hose and assembly and valve are designed with an internal bore allowing a large diameter ball to be dropped (required for acid stimulation). The subsea subsea control module (8) on the Xmas tree is controlled from the producing platform.

摘要： A pipe loosening device and methods are shown. In one example, the pipe loosening device enables a method wherein a pipe to be replaced is deformed but not burst, and a portion of a sidewall of the pipe is forced outward into the surrounding soil to compact a local region of the surrounding soil and loosen the existing pipe. The pipe may then pulled from the ground along an axis of the pipe.

摘要： A horizontal directional drilling system. The system has a pilot drill and an exit side drill, with a drill string extending between them. A backreamer is positioned between the drills to enlarge a borehole. The pilot drill pulls and rotates the backreamer. The exit side drill adds segments to the product pipe and pushes the product pipe into the enlarged borehole. The exit side drill is equipped with a rotational disconnect. The disconnect is engaged to allow torque transfer between a motor and a spindle when adding segments to the product pipe. The disconnect is disengaged to prevent torque transfer between the motor and the spindle when pushing the product pipe into the enlarged borehole.

摘要： A method for offshore dual-drive core drilling with three layers of casings under surge compensation is provided. According to the method, a drilling vessel is located at set latitude and longitude coordinates by a dynamic positioning system; drill pipes are stabilized by a seabed template; torques and drilling pressures can be transmitted during drilling of the casings by means of surge compensation of the casings at a wellhead; during drilling for sampling, the surge compensation can compensate to a certain extent for a change in water depth caused by rising or falling tides, or surge, thereby preventing the casings from colliding with equipment and ensuring the safety of wellhead operation; and the drilling of three layers of casings is achieved by means of dual driver heads to effectively protect a wellbore wall, such that high core-drilling rate and good core-drilling quality are achieved during drilling for sampling.

摘要： A sonic tooling handling apparatus includes a gantry support structure with a base frame structure and an overhead frame structure operatively coupled to the base frame structure. The overhead frame structure has a pair of longitudinal beams and a transverse beam coupled to the pair of longitudinal beams. The transverse beam is movable along each of the pair of longitudinal beams. The gantry support structure includes a lifting device coupled to the transverse beam and is movable along part of the transverse beam. The lifting device includes a sonic tooling clamp. The lifting device may raise or lower sonic tooling held by the sonic tooling clamp. The sonic tooling apparatus further includes a removable sonic tooling holding rack having a plurality of stanchions creating at least one sonic tooling holding space for holding sonic tooling. A method of handling sonic tooling and a pipe tong is also disclosed.

摘要： A guide mechanism may include a first jaw and a second jaw pivotably coupled to the first jaw. The jaws may include a guide having a bottom pocket for seating arrangement on a box end of a first tubular and a top funnel for laterally guiding a pin end of a second tubular into the box end. The guide mechanism may also include a linkage system secured to the first and second jaws to control pivoting motion of the jaws. The guide mechanism may also include a bias mechanism coupled to the linkage system and configured to impart a biasing force on the jaws via the linkage system. The biasing force may be adapted to resist opening of the jaws such that opening of the jaws occurs when a lateral force is applied to the guide mechanism that overcomes the biasing force.
