摘要： Apparatus and methods to steer a hydraulic motor when elongating a wellbore having a non-vertical component that includes a quill adapted to transfer torque, rotation, or position between a drive assembly and a drillstring, a bottom hole assembly (BHA) including a toolface orientation detector and at least one measurement while drilling (MWD) instrument or wireline-conveyed instrument, and a controller configured to transmit operational control signals to minimize friction between a drillstring and a wellbore, wherein the instrument is configured to detect pressure between an external surface of the BHA and an inner diameter of the wellbore.

摘要： A micro grid for an oil field is powered by a utility power grid. A micro grid controller is adapted to prevent excessive or unstable power draw on the utility power grid while allowing uninterrupted power supply for drilling rigs in the oil field. The micro grid controller is adapted to control operation of one or more pieces of electrical equipment on the drilling rigs. The micro grid controller may prioritize operation of the electrical equipment based on relative priority of the operations or based on an operating condition of the drilling rig.
