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.
An undergoing research project called ORCHYD, [3] funded by the European Union (EU) under the Horizon 2020 programme will develop a new drilling technique, fully fluid driven, that combines the DTH mud hammer with a high pressure water jet system [4] that cuts grooves in the rock along with the percussive action. That will help cut the rocks at ...
When the water cut becomes high, or when a workover is considered, the economics will be evaluated [1] and may favor the installation of DOWS technology so that the waste water does not need to be treated at the surface. In those cases, the economics may favor injection of the produced water into a different permeable zone accessible to the ...
In 1956, Carl Johnson of Durox International in Luxembourg developed a method for cutting plastic shapes using a thin stream high-pressure water jet, but those materials, like paper, were soft materials. [4] In 1958, Billie Schwacha of North American Aviation developed a system using ultra-high-pressure liquid to cut hard materials. [5]
This is a welded/machined product which contains a "side pocket" alongside the main tubular conduit. The side pocket, typically 1" or 1½" diameter is designed to contain gas lift valve, which allows flow of High pressure gas into the tubing there by reducing the tubing pressure and allowing the hydrocarbons to move upwards.
The resulting cut is a very smooth cut that does not require any dressing before further pipe recovery operations can take place. [9] 1.375in OD Jet Cutter used for cutting coiled tubing. Jet Cutters. Jet cutters use a circular-shaped charge to produce the cutting action. Jet cutters are capable of severing pipe despite significant downhole ...
It can suck up liquids, e.g., water from a hollow. Typically, vacuum excavation loosens the soil with a blunt-nosed high-pressure air lance or water source and vacuums away loosened material. A suction excavator with vacuum excavation equipment operating in the Netherlands
Managed Pressure Drilling (MPD) is defined by the International Association of Drilling Contractors (IADC) as “an adaptive drilling process used to more precisely control the annular pressure profile throughout the wellbore." The objectives of MPD are “to ascertain the downhole pressure environment limits and to manage the annular hydraulic ...
