Direct drive drawworks
A direct drive drawworks having a first electric motor comprising a first output shaft, a second electric motor comprising a second output shaft, and a drum for storing a flexible line. The drum may be disposed between the first electric motor and the second electric motor. The first output shaft and the second output shaft may each be connected to the drum. The first electric motor and the second electric motor may be collectively operable to rotate the drum. The first output shaft and the second output shaft may be connected to the drum such that the drum rotates at the same speed as the first output shaft and the second output shaft.
RIG OPERATIONS INFORMATION SYSTEM
A system includes a data interface that receives data associated with a plurality of wells; an inference engine that receives and analyzes at least a portion of the data to generate results; and a communication engine that outputs information based at least in part on the results.
Assembly for moving excavation or drilling equipment and actuating method therefor
An assembly for driving excavating equipment for an excavating machine includes a drive assembly sliding along a mast of a machine, for driving the drilling equipment; and an actuator. The drive assembly includes a first structure with guide members for sliding along the mast; and a second support structure to support the drilling equipment. The first and second support structures are mutually movable. The drive assembly has at least two operating configurations, for setting at least two excavation center-to-center distances. In the operating configurations of the drive assembly, the first and second support structures are mutually rigidly and directly constrained. While switching between operating configurations, the first and second support structures are always directly mechanically constrained to each other. The actuator controls movement between the first structure and the second support structure and carries out further operative functions for driving parts of an excavating machine or drilling equipment.
CABLE, IN PARTICULAR FOR DOWNHOLE USE, AND METHOD OF MANUFACTURING SUCH CABLE
The disclosure relates to a cable (100) comprising a core (102) and a plurality of reinforcing elements (107) arranged around the core (102) so as to cover the core (102), wherein each reinforcing element (107) includes at least a bundle of reinforcement fibers compriseing at least one fiber and a thermoset matrix impregnating the bundle of fibers, wherein each reinforcing element (107) is individually tubed with a thermoplastic coating (112).
Drilling installation: handling system, method for independent operations
Drilling installation comprising a cantilever with a drilling floor for performing drilling operations; further comprising an independent operations handling system arranged for handling equipment underneath the drilling floor independent of the drilling operations on the drilling floor, wherein the independent operations handling system comprises a handling element for cooperation with the equipment to be handled, wherein the handling element is extendible underneath the cantilever.
Offshore drilling rig comprising an anti-recoil system
Disclosed herein are embodiments of an offshore drilling rig comprising: a drill floor (107) defining a well center (123); a hoisting system configured to advance a tubular string (128) downwards through the well center (123) and to the seafloor (124) and to apply a lifting force to a tubular string (128) extending through the well center (123) and to the seafloor (124), the lifting force being large enough to support at least a major part of an apparent weight of the tubular string (128); and an anti-recoil system (218) configured to cause, in case of a sudden reduction of a load suspended from the drilling rig, the hoisting system to raise the tubular string (128) while preventing damage to the hoisting system.
Well pipe removal and storage device, system and method
A device, system and method of use for removing well pipe and a subterranean well pump and storing such removed pipe on a spool.
Reel assemblies with automated control systems
A reel assembly for deploying a cable, hose or umbilical connection may include an electronic control unit that may operate to control the reel assembly. A sheave that redirects the direction of the cable, hose or umbilical connection may include sensors that may measure various parameters, such as a measured line tension and/or a length of cable, hose or umbilical connection that has been deployed, and transmit the measured data to the electronic control unit. The electronic control unit may, based on received sensor data, automatically direct the operation of the reel assembly. Optionally, the sensor data and/or user control inputs and system status information may be logged. The system also may use this data to control the system, such as by activating an alarm when a certain alarm limit is exceeded by the data, adjusting parameters of the drive, and the like.
Monitoring rig activities
Image sensors are positioned around a rig floor. An on-site edge or fog computing gateway is communicably coupled to the image sensors. The on-site edge or fog computing gateway includes one or more processors and a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors. The programming instructions instruct the one or more processors to do the following: receive an image stream form at least one of the plurality of image sensors; generate, from the image stream, an operating condition; determine that an automation rule includes the operating condition generated from the image stream; in response to determining that an automation rule includes the operating condition, send an instruction to drive a controllable device; and, in response to sending an instruction to drive the controllable device, drive the controllable device.
Mobile well servicing system and method of using the same
A mobile well servicing system and method are provided for performing well services. The mobile well servicing system can include a work surface on a platform supporting an equipment such a jack, a blowout preventer (BOP), a coiled tubing (CT) injector and a mast. The mast is pivotable between a first position, with a lifting point positioned over the work surface, and a second position, with the lifting point positioned behind the platform. A hoist winch assembly mounted at the platform raises the equipment from the platform when the mast is at the first position. The equipment then pass through a space between two parallel legs of the mast, and lowered to a wellhead when the mast is at the second position. Multiple tasks such as well completion, change of dynamic temperature sensor (DTS) and electric submersible pump (ESP) can be achieved using this system.
