Abstract: A subsea coiled tubing drilling system and a subsea drilling device thereof are provided. The subsea drilling device includes an underwater derrick, a well head device and a dual-roller coiled tubing device, the dual-roller coiled tubing device includes an injection head, a roller for drilling and a roller for running casing, the injection head is arranged right above the well head device, the roller for drilling and the roller for running casing are distributed on two sides of the injection head; both the drilling coiled tubing and the casing running coiled tubing are capable of respectively penetrating through the injection head and the well head device in sequence. Drilling and casing running operations can be realized on the basis of not moving the underwater derrick or changing the self structure state of the underwater derrick, and operation steps can be simplified, and the work efficiency can be improved.

The land-based drilling rig also includes a drill rig floor coupled to the first and second substructures, the drill rig floor including a V-door. The side of the drill rig floor has the V-door defining a V-door side of the drill rig floor, where the V-door side of the drill rig floor is parallel to the first substructure. The first and second substructures pivotably support the drill rig floor. The land-based drilling rig also includes a mast, the mast mechanically coupled to one or more of the first substructure, the second substructure, and the drill rig floor. The mast is pivotably coupled to one or more of the first substructure, the second substructure, and the drill rig floor by a mast pivot point. The mast includes a V-door side, the V-door side of the mast parallel to the first or second substructure. In addition, the land-based drilling rig includes a mast hydraulic lift cylinder coupled to the mast at a mast lift point and a choke manifold, the choke manifold positioned on the drill rig floor.

Abstract: Support systems, apparatus and methods for use with well structures, which may be used to reduce the cost and/or risk of performing procedures on assets, for example, prior to or during well abandonment. A support system includes an actuation system for use with a support member. The support member may be configured for complementary engagement with the actuation system. A cross-over section is configured for use at a lower end of the support member and includes a body portion and a well structure portion. The bore of the cross-over section changes from a first diameter at the body portion to a second diameter at the well structure portion, the second diameter being greater than the first diameter.

Abstract: A drilling rig mast erection system includes a mast support shoe that is fixedly attached to a drilling rig substructure and has a support shoe pinned connection. A bottom mast section has a first mast pinned connection that is adapted to be pivotably connected to the support shoe pinned connection. A mast positioning apparatus is adapted to pivotably position the bottom mast section so that the first mast pinned connection is positioned adjacent to the support shoe pinned connection. The mast positioning apparatus includes a bottom mast support spreader having a first end that is adapted to be pivotably connected to the bottom mast section at a first spreader end pinned connection and a mast erection apparatus having a first end that is adapted to be pivotably connected to the bottom mast support spreader at a first mast erection apparatus pinned connection.

Abstract: A low-profile roller assembly reduces an overall mounting height of walking machines enabling use in a wider variety of structures and locations while also reducing complexity and over cost. The low-profile roller assembly may include a roller device with a substantially flat roller cage with one or more slots configured to hold a single layer of rollers. The roller device may move longitudinally relative to a support foot and a load plate may move longitudinally relative to both the support foot and the roller device. The load plate may laterally displace relative to a longitudinal axis of the support foot or may laterally displace relative to longitudinal axes of both the support foot and the roller device.

Abstract: An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with screw jacks and a means of stabilization during substructure raising. The substructure bracing reduces the overall length, reduces the upper and lower box spans, and balances the raising loads, subsequently lowering the transport weight of the side box such that a commercial walking system may be integrated into the side box and remain there during transport while maximizing the operating drill floor height while minimizing the transport height.
