2. Pressure tank - Wikipedia

   en.wikipedia.org/wiki/Pressure_tank

   Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi ...

3. Steam accumulator - Wikipedia

   en.wikipedia.org/wiki/Steam_accumulator

   Steam can be drawn off as required, either for driving a steam turbine or for process purposes (e.g. in chemical engineering), by opening a steam valve on top of the drum. . The pressure in the drum will fall but the reduced pressure causes more water to boil and the accumulator can go on supplying steam (while gradually reducing pressure and temperature) for some time before it has to be re-char

4. Permanent downhole gauge - Wikipedia

   en.wikipedia.org/wiki/Permanent_Downhole_Gauge

   Systems installed in well casing to read formation pressure directly, suspended systems, and systems built in coil (continuous) tubing are also available. The data that PDGs provide are useful to reservoir engineers in determining the quantities of oil or gas contained below the Earth's surface in an oil or gas reservoir and also which method ...

5. Oil well control - Wikipedia

   en.wikipedia.org/wiki/Oil_well_control

   Pump pressure, which is also referred to as system pressure loss, is the sum total of all the pressure losses from the oil well surface equipment, the drill pipe, the drill collar, the drill bit, and annular friction losses around the drill collar and drill pipe. It measures the system pressure loss at the start of the circulating system and ...

6. 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.

9. Pumping station - Wikipedia

   en.wikipedia.org/wiki/Pumping_station

   The interior of a sewage pump station is a very dangerous place. Poisonous gases, such as methane and hydrogen sulfide, can accumulate in the wet well; an ill-equipped person entering the well would be overcome by fumes very quickly. Any entry into the wet well requires the correct confined space entry method for a hazardous environment. To ...
