  2. Rotary steerable system - Wikipedia

    en.wikipedia.org/wiki/Rotary_steerable_system

    In other words, a tool designed to drill directionally with continuous rotation from the surface, eliminating the need to "slide" a mud motor. The first known patent application is from Christopher G. Cross in 1873 for "Drills for Boring Artesian Wells", [ 1 ] followed in 1884 by the brothers Morris and Clarence Baker for a "Machine for ...

    en.wikipedia.org/wiki/Mud_motor

    A mud motor (or drilling motor) is a progressive cavity positive displacement pump (PCPD) placed in the drill string to provide additional power to the bit while drilling. The PCPD pump uses drilling fluid (commonly referred to as drilling mud, or just mud) to create eccentric motion in the power section of the motor which is transferred as ...

    Suction line (#3) is an intake line for the mud pump to draw drilling fluid from the mud tanks. Swivel (#18) is the top end of the kelly that allows the rotation of the drill string without twisting the block. Traveling block (#11) is the moving end of the block and tackle. Together, they give a significant mechanical advantage for lifting.

    Surface mud systems. In the oil drilling industry, effective solids control can be attributed to the overall performance of all the components of the mud systems.Conditioning the drilling fluid with the goal of dramatically lowering maintenance cost, avoiding excessive chemical treatment and maintaining mud systems volume will decrease the chance of equipment failure, unnecessary high mud ...

    The mud then carries the crushed or cut rock ("cuttings") up the annular space ("annulus") between the drill string and the sides of the hole being drilled, up through the surface casing, where it emerges from the top. Cuttings are then filtered out with either a shale shaker or the newer shale conveyor technology, and the mud returns to the ...

  7. Mud pump - Wikipedia

    en.wikipedia.org/wiki/Mud_pump

    A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling.
