n: see open-hole completion.

a very simple, open hole pay zone completion with a minimum of downhole equipment. Also called an open hole completion. The casing is usually run to the top of the pay and is cemented above the pay only.

n: a method of casingless completion in which low the oil string to the top of oil or gas layer after drill out the pay formation

n: one kinds of open hole completion , that is putting the casing to the bottom of oil layer and then drilling recovery layer.

n: A well completion that has no casing or liner set across the reservoir formation, allowing the produced fluids to flow directly into the wellbore. This type of completion suffers the major disadvantage that the sandface is unsupported and may collapse. Al

a completion without casing.

n: 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 well- head in the production casing;that is, the tool assembly that provides the hydrocarbon flow path or paths.

n: The last working process before the well start to produce,which include open hole completion, sand control completion and tubingless completion,etc.








that processes involved, after drilling, is properly isolate pressures and fluids, and then stimulate or restrain the formations so that hydrocarbons can be produced with minimum amounts of extraneous fluids.
