  • Patent number: 12655752
    Abstract: Methods and systems are disclosed that use a temperature sensor integral to a drill bit while drilling. The temperature sensor is configured to measure temperature associated with a cutting element of the drill bit over time while drilling. The temperature sensor is used to generate time-series temperature data representing temperature of the cutting element of the drill bit over time while drilling. The time-series temperature data is processed to determine at least one condition of the wellbore and/or the drill bit while drilling, wherein the at least one condition relates to at least one of: i) detecting that a steering tool of the BHA of the drill bit is active and operating to control the direction of drilling, ii) detecting backwards whirling while drilling, and iii) detecting a transition between different types of reservoir rock while drilling.

  • Patent number: 12655699
    Abstract: The current invention describes a plug that may be run into a well for example an electric submersible pump without the plug locking into the wellbore casing or setting. The plug may then be allowed to sit within the well for a predetermined period of time during which a dissolvable lock is removed from the plug. With the dissolvable lock removed further downward travel is prevented by the plug locking into place while the electrical submersible pump may be freely retrieved to the surface.

  • Patent number: 12644359
    Abstract: Systems and methods are disclosed herein for simultaneously milling an obstructions and collecting the resulting debris within a wellbore in an oil-and-gas setting. An example debris collection tool can include a motor, centrifugal pump, gear boxes, bailers, and a pass-through milling bit. A series of shafts can pass through the internal components of the tool and cause various components to rotate when driven by the motor. The gear boxes can lower the speed and increase the torque of rotating downhole components. The tool therefore can simultaneously drive the pump and milling bit at different speeds and torques. The centrifugal pump can include a flow control mechanism at allows the tool to control the flow of drilling fluid from the centrifugal pump into the surrounding subsurface.

  • Patent number: 12644340
    Abstract: An electrocrushing drilling apparatus may include a downhole electrocrushing drill assembly that is part of a bottomhole assembly coupled to a downhole end of a coiled tubing drill string. The coiled tubing drill string can be deployed into a wellbore of a hydrocarbon well to advance the wellbore by way of an electrocrushing drilling operation whereby formation rock is fractured by high voltage electrical energy pulses emitted by electrodes of a drill bit of the electrocrushing drill assembly. Potential damage to electronic or other components of the bottomhole assembly due to excess heat generated by power losses of electrocrushing drill assembly can be minimized or prevented by actively cooling the electronic or other components of the bottomhole assembly using a liquid coolant that is conveyed from an earth surface of the well downhole to the bottomhole assembly and passed through the electronic or other components of the bottomhole assembly.

  • Patent number: 12637923
    Abstract: A sub-surface safety valve (SSSV) for use in a low temperature downhole environment. The low temperature environment can be created by injection of fluid such as carbon dioxide. The low temperature downhole environment may be detrimental to the SSSV by damaging elastomer seals. The disclosed SSSV utilizes non-elastomeric seals and metal-to-metal seals between components. The SSSV utilizes metal-to-metal threads between body joints eliminating the need for an elastomers in the threads between body joints. Creating a SSSV with an elastomer seal reduces fatigue and damage in a low temperature environment.
