A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/disengaging the top drive and a stand constrained by the clasp.

High trip rate drilling rig

A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end.

Tubular delivery arm for a drilling rig

A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/dis engaging the top drive and a stand constrained by the clasp.

A rig system includes a first base box and a second base box extending parallel to and offset from the first base box, such that an open space is defined therebetween. A rig floor is connected to the first and second base boxes and spans the open space. A mast is coupled to the rig floor. A rig-raising system is configured to raise the rig floor vertically above the ground. A combined local equipment room (LER) and drilling control room (DCR) skid is connected to the rig floor and configured to be raised with the rig floor. A reel skid is positioned at least partially vertically below the LER/DCR skid. A setback structure extends between the first and second base boxes and blocks the open space on at least one end.

Rig structure and rig-up process

A drilling rig system for obtaining high trip rates separates the transport of tubular stands in and out of their setback position into a first function, delivery and retrieval of tubular stands in well center position as a second function; and the functions intersect at a stand hand-off position where tubular stands are set down for exchange between tubular handling equipment. A drilling rig has a tubular delivery arm that vertically translates the mast in a non-conflicting path with a top drive. The tubular delivery arm is operable to deliver tubular stands between a catwalk, stand hand-off, mousehole, and/or well center positions. An upper racking arm moves tubular stands between a racked position in the racking module and a stand hand-off position between the mast and racking module. An upper support constraint stabilizes tubular stands at the stand hand-off position.

The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.

Fast transportable drilling rig system

A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end. The dolly vertically translates the front side of the mast in response to actuation of a hoist at the crown of the mast. The tubular delivery arm translates the mast in non-conflicting passage of a top drive connected to the same mast, for positioning a tubular stand over the centerline of the wellbore, a mousehole, or a stand hand-off position.

The present invention relates to a positioning system for service lines. Generally, the invention relates to a mechanism for the deployment, retraction, and transportation of fixed-length service lines such as electrical, pneumatic, hydraulic, and communication resources necessary to the operation of a drilling rig used for subterranean exploration. More particularly, the invention provides an extendable cable positioning system for use with drilling rigs where pad drilling will require relatively short distance movements of the drilling rig, and it is desirable to leave the energy resource systems stationary.

Service line transport and deployment system

The disclosed embodiments provide a drilling rig having a tubular delivery arm that vertically translates the mast in a non-conflicting path with a retractable top drive. The retractable top drive translates a well center path and a rearward retracted path. The tubular delivery arm is operable to deliver tubular stands between a catwalk, stand hand-off, mousehole, and well center positions. An upper racking mechanism moves tubular stands between a racked position of the racking module and a stand hand-off position between the mast and racking module. A lower racking mechanism controls the movement of the lower end of the tubular stand being moved coincident to the movements of the upper racking mechanism. An upper support constraint stabilizes tubular stands at the stand hand-off position. A lower stabilizing arm guides the lower end of tubular stands between the catwalk, stand hand-off, mousehole, and well center positions.

The present invention relates to a new apparatus and method for use in subterranean exploration. The present invention provides a rapid rig-up and rig-down of a drill floor mounted device such as a pipe racking system. In particular, the present invention discloses a system and method for rapid deployment of a drill floor mounted pipe racking system that is capable of being retrofit to an existing drilling rig.

System and method for raising and lowering a drill floor mountable automated pipe racking system

The present invention discloses an automatic drill floor to substructure latching system that adds to the safety of drilling operations. In particular, the present invention is applicable for rapid and safe locked connection of a drilling rig side box to the drilling rig base box such that weight imbalances incurred when raising of the drilling rig mast will not result in unsecured and unsafe separation of the side box and base box.
