    • The present disclosure relates generally to a well boring apparatus, and associated components, for drilling wellbores without the necessity of traditional well drilling equipment. The well boring apparatus operates on similar principles as a tunnel boring apparatus. The well boring apparatus is self-propelled, steerable, and can be launched from a topside vessel or directly from a seabed installation. The well boring apparatus is fully instrumented and capable of analyzing the surrounding environment including the temperature, pressure, acidity and the presence of particular chemicals. The well boring apparatus is highly modular such that it can be configured for different tasks. The well boring apparatus can include components to case/line the wellbore during drilling, eliminating the need for running casing/lining. Further, the well boring apparatus can be incorporated in a drilling system in which cuttings are processed at the seabed, thereby removing the need for a drilling riser.
    • 本公开一般涉及一种用于钻井井筒的钻井设备和相关部件,而不需要传统的钻井设备。 钻孔设备的工作原理与隧道钻孔设备类似。 钻井设备是自推进的,可操纵的,可以从顶部船只或直接从海床安装发射。 钻孔设备完全仪器化,能够分析周围环境,包括温度,压力,酸度和特定化学品的存在。 钻孔设备高度模块化,可以配置为不同的任务。 钻井设备可以包括在钻井期间壳体/管线井的部件,从而不需要运行套管/内衬。 此外,钻井设备可以结合在其中在海床处理切屑的钻井系统中,从而不需要钻井立管。

    • Systems and methods are presented for drilling a wellbore with a portion having a short radius of curvature. The systems include a drill assembly having a motor and a tubular housing. An actuator is at least partially disposed within the tubular housing and couples the motor to the tubular housing. The actuator is configured to selectively articulate the drill assembly between a straight configuration and a bent configuration. At least one torque anchor is fluidly-coupled to a trailing end of the drill assembly. Methods are presented for selectively articulating the drill assembly to form the wellbore, including the portion having short radius of curvature. Other systems and methods are presented.
