n: 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.

n: A completion design in which the reservoir fluids are produced through small-diameter casing. The absence of a separate tubing string significantly limits the operating and contingency options available for the well.

a low cost completion or multiple completion in which the tubing strings are cemented directly in the hole. There is no outer casing. Due to the small tubing diameters, potential to repair or re-enter the well for repairs is limited.

n: The lost or fractured tubular fish in the well,for example, drill string ,casing and core barrel.

n pI: any kind of pipe. Oilfield tubular goods include tubing, casing, drill pipe, and line pipe. Also called tubulars.

n: The general designation of all kinds of pipe,which include casing ,drill string ,oil tube and general steel tube.

n: a pipeline heating device consisting of a resistance wire surrounded by an insulating material such as magnesium oxide and contained in a metal tube.

n pi: shortened form of tubular goods.

n: see hoisting engine.

a winch line or other device that can pull equipment into place.

n: the treeless plain characteristic of much of the Arctic. Although the tundra remains frozen for much of the year, it is highly sensitive to environmental disturbance, and special pipeline construction techniques are required there.

n: The icy road be layed by fresh water on the tundra in North Pole,which be used to transport the rig to new well site.

n: a fine, very hard, gray crystalline powder, a compound of tungsten and carbon. This compound is bonded with cobalt or nickel in cemented carbide compositions and used for cutting tools, abrasives, and dies.

n: The gray stiff powder,cannt dissolve in the water, but can dissolve preferablly in the nitric acid and hydrofluoric acid.

a hard, abrasion resistant compound used in cutting tools such as mills and bits.

n: a type of roller cone bit with inserts made of tungsten carbide. Also called tungsten carbide insert bit.

n: The cone bit that be fixed tungsten carbide alloy tooths on the bore of shell.
