2. Baptist well drilling - Wikipedia

   en.wikipedia.org/wiki/Baptist_well_drilling

   If required, the upper part of the well can be reamed and cased with larger diameter pipe (3 or 5 inches), to accommodate larger pumps. A shallow (large diameter) rope pump, for example, may require a wider well and submersible pumps commonly need at least 4". Note that there is no need to enlarge the entire depth of the borehole: reaming until ...

3. Completion (oil and gas wells) - Wikipedia

   en.wikipedia.org/wiki/Completion_(oil_and_gas_wells)

   Gas lift well: gas is fed into valves installed in mandrels in the tubing strip. The hydrostatic head is lowered and the fluid is gas lifted to the surface. Single-well alternate completions: in this instance there is a well with two zones. In order to produce from both the zones are isolated with packers.

4. Treadle pump - Wikipedia

   en.wikipedia.org/wiki/Treadle_Pump

   A treadle pump is a human-powered suction pump that sits on top of a well and is used for irrigation. [1] It is designed to lift water from a depth of seven metres or less. The pumping is activated by stepping up and down on a treadle , which are levers, which drive pistons, creating cylinder suction that draws groundwater to the surface.

5. Well control - Wikipedia

   The LOT determines the pressure and/or fluid weight the test zone below the casing can sustain. The fluid in the well must be circulated clean to ensure it is of a known and consistent density. If mud is used, it must be properly conditioned and gel strengths minimized. The pump used should be a high-pressure, low-volume test, or cementing pump.

6. Gas lift - Wikipedia

   en.wikipedia.org/wiki/Gas_lift

   [3] The gas-lift mandrel is a device installed in the tubing string of a gas-lift well onto which or into which a gas-lift valve is fitted. There are two common types of mandrels. In a conventional gas-lift mandrel, a gas-lift valve is installed as the tubing is placed in the well. Thus, to replace or repair the valve, the tubing string must be ...
