  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. List of components of oil drilling rigs - Wikipedia

    en.wikipedia.org/wiki/List_of_components_of_oil...

    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 ...

  4. 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. They have been called Archimedes ...

  5. Mud systems - Wikipedia

    en.wikipedia.org/wiki/Mud_systems

    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 ...

  6. 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 ...

  7. Measurement while drilling - Wikipedia

    en.wikipedia.org/wiki/Measurement_while_drilling

    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 ...

  8. Drill pipe - Wikipedia

    en.wikipedia.org/wiki/Drill_pipe

    The BHA will be made of thicker walled heavy weight drill pipe (HWDP) and drill collars, which have a larger outside diameter and provide weight to the drill bit and stiffness to the drilling assembly. Other BHA components can include a mud motor, measurement while drilling (MWD) apparatus, stabilizers, and various specialty downhole tools.

  9. Mud agitator - Wikipedia

    en.wikipedia.org/wiki/Mud_agitator

    A mud agitator is used in surface mud systems to suspend solids and maintain homogeneous mixture throughout the system. A mechanical agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to ...
