  2. Mud motor - Wikipedia

    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 ...

  3. 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 ...

  4. Directional drilling - Wikipedia

    en.wikipedia.org/wiki/Directional_drilling

    Combined, these survey tools and BHA designs made directional drilling possible, but it was perceived as arcane. The next major advance was in the 1970s, when downhole drilling motors (aka mud motors, driven by the hydraulic power of drilling mud circulated down the drill string) became common. These allowed the drill bit to continue rotating ...

    Mud pump (#4) is a reciprocal type of pump used to circulate drilling fluid through the system. Mud tank (#1) is often called mud pits and stores drilling fluid until it is required down the wellbore. Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame ...

    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 ...

  8. Screw-propelled vehicle - Wikipedia

    en.wikipedia.org/wiki/Screw-propelled_vehicle

    A screw-propelled vehicle. A screw-propelled vehicle is a land or amphibious vehicle designed to cope with difficult terrain, such as snow, ice, mud, and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving.

    Mud flow volume; Mud Motors. Use of this information can allow the operator to drill the well more efficiently, and to ensure that the MWD tool and any other downhole tools, such as a mud motor, rotary steerable systems, and LWD tools, are operated within their technical specifications to prevent tool failure. This information is also valuable ...
