    en.wikipedia.org/wiki/Tripping_(pipe)

    Tripping pipe (or "Making a round trip" or simply "Making a trip") is the physical act of pulling the drill string out of the wellbore and then running it back in. This is done by physically breaking out or disconnecting (when pulling out of the hole) every other 2 or 3 joints of drill pipe at a time (called a stand ) and racking them ...

    en.wikipedia.org/wiki/Drill_cuttings

    Drill cuttings [1] are broken bits of solid material removed from a borehole drilled by rotary, percussion, or auger methods and brought to the surface in the drilling mud. Boreholes drilled in this way include oil or gas wells, water wells, and holes drilled for geotechnical investigations or mineral exploration. [2]

    As of July 2010 it was unknown whether the tubing might have been casing that shot up through the well or perhaps broken drill pipe that dropped into the well. The DNV final report indicated that the second tube was the segment of the drill string that was ejected after being cut by the blow out preventer shears.

  6. Snubbing - Wikipedia

    Once a sufficient amount of pipe has been run into the hole, the weight becomes sufficient to overpower the wellbore pressure and the pipe naturally wants to fall in the hole; this is heavy-pipe. At this point, the snubbing mechanism is changed over to the one which provides upward force to hold the pipe and lower it controllably into the well.

  7. Pipe recovery operations - Wikipedia

  8. Slickline - Wikipedia

    en.wikipedia.org/wiki/Slickline

    Slickline is more commonly used in production tubing. The wireline operator monitors at surface the slickline tension via a weight indicator gauge and the depth via a depth counter 'zeroed' from surface, lowers the downhole tool to the proper depth, completes the job by manipulating the downhole tool mechanically, checks to make sure it worked if possible, and pulls the tool back out by ...

  9. Baptist well drilling - Wikipedia

    en.wikipedia.org/wiki/Baptist_well_drilling

    The standard drill bit is based on 1.25 inches (3.2 cm) water pipe fittings and unless a larger diameter is required, the borehole is cased with 1.5 inches (3.8 cm) PVC pipe. The main drill tool consists of a length of metal pipe with a bit/valve. Extensions are standard PVC potable water pipes. No temporary casing is used.
