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.
Petroleum production engineers design and select subsurface equipment to produce oil and gas well fluids. [1] They often are degreed as petroleum engineers, although they may come from other technical disciplines (e.g., mechanical engineering, chemical engineering, physicist) and subsequently be trained by an oil and gas company.
The stages of operation of a plunger lift. A plunger lift is an artificial lift method of deliquifying a natural gas well.A plunger is used to remove contaminants from productive natural gas wells, such as water (in liquid, mist, or ice forms), sand, oil and wax.
An airlift pump, powered by compressed air, raises fluid by entraining gas to reduce its density. 1. air supply 2. liquid supply 3. air inlet port
A production packer [1] is a standard component of the completion hardware of oil or gas wells used to provide a seal between the outside of the production tubing and the inside of the casing, liner, or wellbore wall. Based on their primary use, packers can be divided into two main categories: production packers and service packers.
Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...
In 2012, Dover acquired Production Control Systems. PCS has roots in plunger lift and well control holding several patents on plungers and associated equipment. PCS also provides a suite of well controllers and automation systems, and solutions [buzzword] for gas lift and nitrogen generation. They merged with Ferguson Beauregard to become PCS ...
A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.
