A single well that produces from two separate formation at the same time. production from each zone is segregated by running two tubing strings with packers inside the single string of production casing, or by running one tubing string with a packer through one zone while the other is produced through the annulus. in a [...]

A method of preparing a well for production in which no production casing or liner is set opposite the producing formation. reservoir fluids flow unrestricted into the open wellbore. an open-hole completion has limited use in rather special situations. also called a barefoot completion.

A method of producing a well in which only production casing is set through the pay zone, with no tubing or inner production string used to bring formation fluids to the surface. this type of completion has its best application in low-pressure, dry-gas reservoirs.

1. refers to the installation of permanent equipment for the production of oil or gas.
2. the hardware used to optimize the production of hydrocarbons from the well. this may range from nothing but a packer on tubing above an openhole completion (“barefoot” completion), to a system of mechanical filtering elements outside of perforated pipe, to a [...]

A well completion in which the production casing is less than 4.5 inches in diameter. compare conventional completion.

A single bore-hole completion where there are distinct surface-to-zone tubing strings with isolation from each other.

A completion that is not stimulated.

A completion where ct and associated ct-mounted hardware is used as the primary completion flow path.

A completion that uses flow to purposely increase the size of the open hole wellbore.

A completion with casing set through the interval and cemented.

1. The activities and methods of preparing a well for the production of oil and gas or for other purposes, such as injection; the method by which one or more flow paths for hydrocarbons are established between the reservoir and the surface.
2. The system of tubulars, packers, and other tools installed beneath the wellhead [...]

A packer used for the well completion method of gravel packing.

See open-hole completion

A worker in the oil industry, especially one in the field.

Those portions of reservoir gas which are liquefied at the surface in field facilities or gas processing plants.
