- Houston TX, US
Christopher MAGNUSON - Houston TX, US

International Classification:

E21B 19/16

Abstract:

A system with multiple spinners in a spinner assembly, each spinner comprising a drive shaft, a sleeve with arcuate segments surrounding the drive shaft, a first cap that receives a first end of the sleeve and a second cap that receives a second end of the sleeve, which secures the sleeve to the drive shaft. A system with two spinner subassemblies in a spinner assembly, and with a coupling assembly that moves the subassemblies a same distance in opposite directions relative to a center axis of the spinner assembly. A method can include securing multiple arcuate segments of the sleeve to a drive shaft of the spinner by inserting a first end of the sleeve into a first recess of a first cap and inserting a second end of the sleeve into a second recess of a second cap.

Inventors:

- Houston TX, US
Christopher Magnuson - Houston TX, US

International Classification:

E21B 19/15

Abstract:

An apparatus for moving a tubular may include a column vertically extending from a drill floor, the column defining an axis; a lower carriage connected to the column and configured to carry the column along the drill floor; an upper arm assembly movable along the column, the upper arm assembly being configured to connect with a tubular; and a lower arm assembly having a lower gripper head configured to attach to the tubular, the lower arm assembly being movable to displace the lower gripper head between a position on a first side of the axis and a position on a second side of the axis.

International Classification:

E21B 15/00
E21B 19/06

Abstract:

A drilling assembly that can include a first mast, a second mast, a water table coupled between the first and second masts, and a plurality of sheaves coupled to the water table and adapted to translate along a plane oriented generally perpendicular to a height of at least one of the first or second mast. A drilling assembly that can include a mast having a generally C-shaped support structure, as viewed from a top view, and an opening disposed within the support structure, where the mast is disposed adjacent to a wellbore, and where the opening is adapted to permit passage of tubulars from an external position to the wellbore through the mast. A drilling assembly that can include a mast, a water table coupled to the mast, and a drawworks disposed adjacent to the mast, where the drawworks is adapted to laterally translate relative to the mast.

International Classification:

E21B 19/06
E21B 41/00
E21B 19/14

Abstract:

The systems, devices, and methods described herein relate to tubular detection on a gripperhead system for a drilling rig. The gripperhead system includes a grabber and a gripper each having first and second grabber arm and pistons connected to the first and second arms. Each arm may also include an inwardly facing gripping surface forming at least a portion of a chamber sized to receive a portion of a cylindrical tubular. One or more sensors may be disposed on the gripperhead system, including proximity sensors disposed on the arms, inductive sensors disposed within the pistons, and ultrasonic sensors disposed on other features of gripperhead system. The one or more sensors may be configured to determine the position of the tubular in relation to the arms, measure the size of the tubular, measure the compression force of the grabber, and ensure that the tubular is secured within the grabber.

International Classification:

E21B 19/16
E21B 19/15
E21B 19/20

Abstract:

Systems and methods for operating a land-based drilling rig apparatus include a dual-activity mast having a first fingerboard supported by the mast and disposed on a first side of the well center bore, and include a second fingerboard supported by the mast and disposed on a second side of the well center bore. The first and second fingerboards may permit simultaneous operations, such as tripping and casing stand assembly.

International Classification:

E21B 44/02
E21B 47/06
E21B 19/20
E21B 21/08

Abstract:

The systems, devices, and methods described herein describe a control system that automatically determines a trip speed for a surge operation or a swab operation. The control system is used to automatically adjust the trip speed during the respective surge or swab operation in order to optimize the trip speed according to the changing environment of the wellbore that the bottom hole assembly traverses without exceeding the fracture gradient in the wellbore location. A well plan identifies formations along the wellbore route, dynamic real-time tracking of the tubulars added to the drill string and removed therefrom identifies the current location of the BHA in the wellbore, and pressure and fractional gradient at the location of the BHA, and in some embodiments a real-time pressure measurement from the BHA, together are used to automatically determine the maximum tripping speed possible for the formation that the BHA is traversing.
