Artificial lift is the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well.
Dover Artificial Lift was formed in 2009 including Norris Rods, Fergusen Beauregard, Alberta Oil Tool, Norrisseal, C-Tech Design & Manufacturing, and Theta Oilfield Services Inc. In 2011, Dover Corporation acquires Harbison Fischer [ 11 ] and Oil Lift Technology Inc. [ 12 ] Both companies became member brands within Norris Production Solutions.
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 pulled.
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.
JJ Arps produced a working directional and resistivity system in the 1960s. [2] Competing work supported by Mobil, Standard Oil and others in the late 1960s and early 1970s led to multiple viable systems by the early 1970s, with the MWD of Teleco Oilfield Services, systems from Schlumberger (Mobil) Halliburton and BakerHughes.
Shares of New Brunswick, New Jersey-based J&J edged up 32 cents to $152.82 after markets opened Friday. The Dow Jones Industrial Average, of which J&J is a component, also rose slightly.
Submersible pumps are used in oil production to provide a relatively efficient form of "artificial lift", able to operate across a broad range of flow rates and depths. [ 3 ] [ 4 ] By decreasing the pressure at the bottom of the well (by lowering bottom-hole flowing pressure, or increasing drawdown), significantly more oil can be produced from ...
Seawater lift pumps deliver 4,000m 3 /hr at 12 barg to the seawater coarse filtration package. After filtration the water is used to cool the cooling medium in the cooling medium plate exchangers. 2322.7 m 3 /hr of seawater now at 6 barg and 20°C is routed to the fine filters and then to the sulphate removal membrane where reverse osmosis is ...
