n: a method for completing a well in which tubing is set inside 4.5-inch (1.4-centimetre) or larger casing. Compare miniaturised completion. conventional coupling n: piping configuration that uses ten diameters of straight full pipe upstream of a meter and straightening vanes;the downstream contains five or more full pipe diameters.

n: A kind of well completion that oil tube is tripped in above the casing whose diameter is 4 1/2.

n: a length of straight pipe containing straightening vanes or the equivalent and installed at the inlet of a flowmeter to eliminate swirl from the liquid from entering the meter and causing measurement errors.

n pi: bundles of smalldiameter tubing tack-welded together in a concentric pattern and placed in the upstream section of an orifice-meter run for the purpose of reducing considerably the amount of straight pipe required upstream of the orifice. They eliminate swirls and crosscurrents set up by the pipe fittings and valves preceding the meter tube.
