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: 1. a string of pipe used to case open hole below existing casing. A liner extends from the setting depth up into another string of casing, usually overlapping about 100 feet (30.5 metres) above the lower end of the intermediate or the oil string. Liners are nearly always suspended from the upper string by a hanger device. 2. a relatively short length of pipe with holes or slots that is placed opposite a producing formation. Usually, such liners are wrapped with specially shaped wire that is designed to prevent the entry of loose sand into the well as it is produced. They are also often used with a gravel pack. 3. in jet perforation guns, a conically shaped metallic piece that is part of a shaped charge. It increases the efficiency of the charge by increasing the penetrating ability of the jet. 4. a replaceable tube that fits inside the cylinder of an engine or a pump. See cylinder linel:

n: a string of the casing that only extends back to inside the previous casing shoe and not back to surface as other casing strings do.

n: 1. the last string of casing set in a well. 2. the string of casing that is set at the top of or through the producing zone, often called the oil string or production casing.

in a side-by-side dual completion, the tubing string that connects the deeper zone to the surface.

n: the final string of casing set in a well after the productive capacity of the formation has been determined to be sufficient. Also called the long string or production casing.

n: The serial casing with mesh,which be situated at the bottom of oil string.

n: see wire-wrapped screen. screw packer n: a packer in which the packing element is expanded by rotating the pipe. It is used when it is not desirable to put tubing weight on the packer. scrub v: to remove certain constituents of a gas by passing it through a scrubber in which the gas is intimately mixed with a suitable liquid that absorbs or washes out the constituent to be removed.

n: The serial casing with mesh,which be situated at the bottom of oil string.
