A land-based drilling rig includes a drill rig floor and a subfloor, the subfloor supporting the drill rig floor. The land-based drilling rig also includes a plurality of substructure boxes, the substructure boxes supporting the subfloor, each substructure box including a lower substructure box and two upper substructure boxes, wherein there is a gap between the two upper substructure boxes. In addition, the land-based drilling rig further includes a mast, the mast mechanically coupled to the drill rig floor.

Side saddle traversable drilling rig

A method of building and operating a land-based drilling rig with a high-capacity mast include providing a platform collapsed on a substructure over a proposed well drilling location and building the high-capacity mast in a horizontal condition by attaching a lower portion of the high-capacity mast to the platform. The high-capacity mast having an opening formed therein sized to accommodate four Range 2 pipes or three Range 3 pipes. The high-capacity mast may be raised from the horizontal condition to a vertical condition by pushing the side of the high-capacity mast to pivot the high-capacity mast about a pivot point on the platform. The platform may be raised from a collapsed condition to a raised condition over the substructure. Some implementations include dual racking boards on the high-capacity mast.

High-capacity mast on a drilling rig

A pipe handling system can include a bridge disposed in an inclined position, having first and second rails with a space therebetween, and an arm coupled to the first and second rails, the arm being configured to manipulate a tubular through the space between the first and second rails. A method that can include gripping a tubular at a well center on a rig floor via an arm coupled to a bridge, the bridge comprising first and second rails with a space therebetween, moving the tubular from the well center and through the space, and moving the tubular along the bridge via the arm, with the bridge being inclined from a horizontal storage area to the rig floor.

Robotic pipe handler systems

A mast assembly for a drilling rig includes a mast formed from a plurality of mast subunits. The mast assembly includes a lower drilling machine, upper drilling machine, and upper mud assembly, each of which is coupled to and movable vertically relative to the mast. The mast subunits are separable when the mast is in a transport configuration such that the LDM is positioned in a first subunit and the UDM is in a second subunit of the mast when the mast is in the transport configuration. The mast assembly may be used during a continuous drilling operation.

Mast assembly for drilling rig

A drilling rig includes a rig floor, first and second support structures, a mast, a lower drilling machine, a continuous drilling unit, an upper drilling machine, and an upper mast assembly. The rig floor includes a V-door defining a V-door axis extending perpendicularly from the side of the rig floor that includes the V-door. The first and second support structures define a traverse corridor having a traverse corridor axis, wherein the traverse corridor axis is perpendicular to the V-door axis. The drilling rig may be used for continuous drilling of a wellbore.

Side saddle slingshot continuous motion rig

A system for performing a subterranean operation, where the system may include a substructure of a rig configured to move from a first position to a second position, a first platform overlying and coupled to the substructure, a second platform overlying and coupled to the substructure, with the first platform configured to move independently from and relative to the substructure and the second platform, and with the second platform configured to move independently from and relative to the substructure and the first platform.

Dual mast rig with independently adjustable platforms

A land-based drilling rig includes a first substructure and a second substructure, the second substructure being positioned generally parallel to the first substructure. 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.

Side saddle drilling rigs

A side saddle slingshot drilling rig includes a left and right substructure including a left and right lower box. The side saddle slingshot drilling rig includes a drill rig floor mechanically and pivotably coupled to the left and right lower boxes such that it is pivotably movable from a lowered position to a raised position. The drill rig floor includes a V-door. The V-door is positioned on the V-door side of the drill rig floor. The V-door side of the drill rig floor is oriented to face the right substructure. A mast coupled to the drill rig floor may include an open side, defining a mast V-door side. The mast V-door side may be oriented to face the right substructure. The mast may pivot into its raised position or may be a bootstrap mast.

Side saddle slingshot drilling rig

A side saddle slingshot drilling rig includes a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other. The right substructure includes a right lower box and a first strut, the first strut pivotably coupled to the drill rig floor and pivotably coupled to the right lower box. The left substructure includes a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box. The side saddle slingshot drilling rig also includes a drill rig floor, the drill rig floor including a V-door. The side of the drill rig floor has the V-door defining the V-door side of the drill rig floor, the V-door side of the drill rig floor parallel to the right substructure. The side saddle slingshot drilling rig further includes a mast, the mast including an open side defining a mast V-door side. The open side is oriented to face perpendicular to the right substructure. The mast is pivotably coupled to the drill rig floor by one or more mast pivot points and one or more lower mast attachment points, the mast being pivotable in a direction parallel to the V-door side of the drill rig floor or the mast being pivotable in a direction perpendicular to V-door side of the drill rig floor. The mast includes two or more subunits, wherein the two or more subunits are pinned together.

Side-saddle cantilever mast

A drilling rig may include a right substructure, left substructure, and a drill floor. The drill floor may be pivotably coupled to lower boxes of the left and right substructure by struts. The substructures may include hydraulic cylinders positioned to raise the drill floor and a mast coupled to the drill floor into a raised position.

Mast and substructure

An automated drilling rig system includes a drilling rig and a catwalk system. The drilling rig includes a rig floor, a substructure, a mast, a top drive, and a pipe handling apparatus. The pipe handling apparatus includes a column coupled to the rig floor at a position offset from the well centerline. The catwalk system includes a pipe tub, a catwalk lift frame, and a catwalk assembly. The pipe tub is configured to store one or more tubular members for use with the drilling rig. The catwalk assembly includes a base and a catwalk slide. The catwalk lift frame is coupled to the base of the catwalk assembly and extends substantially vertically to the rig floor. The catwalk slide is coupled to the catwalk lift frame at a first end and pivotably coupled to the base at a second end via a leveling strut. The catwalk slide includes a skate adapted to slide along the length of the catwalk slide.
