    KBUG – kelly bushing underground (drilling up in coal mines, West Virginia, Baker & Taylor drilling) KCI – potassium chloride; KD – kelly down; KMW – kill mud weight; KOEBD – gas converted to oil-equivalent at 6 million cubic feet = 1 thousand barrels; KOH – potassium hydroxide; KOP – kick-off point (directional drilling) KOP ...

  3. Mud motor - Wikipedia

    en.wikipedia.org/wiki/Mud_motor

    Steerable motors are used to drill the kick-off point. When drilling the kick-off point be sure to avoid drilling a soft formation immediately below a hard one. In hard abrasive formations the high-side forces at kick off can cause severe bit shank wear. Ideally the kick-off point should be selected in a non-abrasive homogenous formation. [2]

  4. Oil well control - Wikipedia

    en.wikipedia.org/wiki/Oil_well_control

    Shut-in drill pipe pressure (SIDPP), which is recorded when a well is shut in on a kick, is a measure of the difference between the pressure at the bottom of the hole and the hydrostatic pressure (HSP) in the drillpipe. During a well shut-in, the pressure of the wellbore stabilizes, and the formation pressure equals the pressure at the bottom ...

    Free point: The highest point at which the drill pipe is "free" or not stuck. Free-point tools are designed to measure torque and stretch in tubing, casings, and drill pipes and to provide accurate free pipe indication. A common method which involves deploying a wireline device to estimate the depth at which the pipe string is stuck.

    It is based on pore pressure, kick tolerance, casing functions, casing design and cementing. It is sometimes related to drilling and petroleum engineering . [ 1 ]

  7. Mud engineer - Wikipedia

    en.wikipedia.org/wiki/Mud_engineer

    Mud is a vital part of drilling operations. It provides hydrostatic pressure on the borehole wall to prevent uncontrolled production of reservoir fluids, lubricates and cools the drill bit, carries the drill cuttings up to the surface, forms a "filter-cake" on the borehole wall to prevent drilling fluid invasion, provides an information medium for well logging, and helps the drilling by ...

    In early 1947, Superior Oil erected a drilling and production platform in 20 feet (6.1 m) of water some 18 miles (29 km) off Vermilion Parish, La. But it was Kerr-Magee , as operator for partners Phillips Petroleum and Stanolind Oil & Gas that completed its historic Ship Shoal Block 32 well in October 1947, months before Superior actually ...

  9. Borehole - Wikipedia

    en.wikipedia.org/wiki/Borehole

    K.S. Tom describes the drilling process: "The Chinese method of deep drilling was accomplished by a team of men jumping on and off a beam to impact the drilling bit while the boring tool was rotated by buffalo and oxen." [4] This was the same method used for extracting petroleum in California during the 1860s (i.e. "kicking her down").
