2. Pumpjack - Wikipedia

   en.wikipedia.org/wiki/Pumpjack

   A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.

   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. Drawdown (hydrology) - Wikipedia

   en.wikipedia.org/wiki/Drawdown_(hydrology)

   Aquifer test (or a pumping test) is a field experiment in which a well is pumped at a controlled rate and the aquifer's response (drawdown) is measured in one or more observation wells. [ 5 ] Cone of depression is a conically-shaped depression that is produced in a water table as a result of pumping water from a well at a given rate.

5. Gas lift - Wikipedia

   en.wikipedia.org/wiki/Gas_lift

   A gas lift or bubble pump is a type of pump that can raise fluid between elevations by introducing gas bubbles into a vertical outlet tube; as the bubbles rise within the tube they cause a drop in the hydrostatic pressure behind them, causing the fluid to be pulled up.

6. Mud pump - Wikipedia

   en.wikipedia.org/wiki/Mud_pump

   A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling.

   = where ΔV is the change in volume, P is the pressure at surface and V is the volume of fluid unpressurised. k is a compression factor approximately 3.5×10 −6 psi −1 . For example, a volume of 300 bbl is to be filled with brine and pressurised to 3000 psi at the surface.
