  2. Casing (borehole) - Wikipedia

    en.wikipedia.org/wiki/Casing_(borehole)

    Deeper strings usually are not cemented all the way to the surface, so the weight of the pipe must be partially supported by a casing hanger in the wellhead. Casing that is cemented in place aids the drilling process in several ways: [2] Prevents contamination of fresh water well zones.

  3. Tube well - Wikipedia

    en.wikipedia.org/wiki/Tube_well

    A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-wide, stainless steel tube or pipe is bored underground. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.

  4. Completion (oil and gas wells) - Wikipedia

    Single-well concentric kill string: within the well a small diameter concentric kill string is used to circulate kill fluids when needed. Single-well 2-tubing completion: in this instance 2 tubing strings are inserted down 1 well. They are connected at the lower end by a circulating head.

    The point is simply hammered into the ground, usually with a tripod and driver, with pipe sections added as needed. A driver is a weighted pipe that slides over the pipe being driven and is repeatedly dropped on it. When groundwater is encountered, the well is washed of sediment and a pump installed. [17]

  6. Driller's depth - Wikipedia

    en.wikipedia.org/wiki/Driller's_depth

    For some deep wells, e.g. 7,000 m or 25,000 ft deep, the drill pipe elongation due to its own weight and temperature must be taken into account. This can be on the order of 24 m (80 ft). Wireline does not behave this way: it tends to lengthen under tension but shorten with increasing temperature.

  7. Depth in a well - Wikipedia

    en.wikipedia.org/wiki/Depth_in_a_well

    It is the most common method of reference for locations in the well, and therefore, in oil industry speech, "depth" also refers to the location itself. Strictly, depth is a vertical coordinate related to elevation, albeit in the opposite direction. However, "depth" in a well is not necessarily measured vertically or along a straight line.

  8. Casing string - Wikipedia

    en.wikipedia.org/wiki/Casing_string

    Depending on the conditions encountered (e.g., zones of differing formation pressure gradients), three or four casing strings may be required to reach the target depth. The cost of the casing can constitute 20-30% of the total cost of the well [citation needed], and failure can be catastrophic. Great care must therefore be taken when designing ...

  9. Baptist well drilling - Wikipedia

    en.wikipedia.org/wiki/Baptist_well_drilling

    Baptist well drilling diagram in Spanish. Baptist well drilling is a very simple, manual method to drill water wells. The Baptist drilling rig can be built in any ordinary arc welding workshop and materials for a basic version costs about 150 US dollars (2006 prices). In suitable conditions, boreholes over 100 m deep have been drilled with this ...
