n: a tool used to gouge and clean junk and debris from the casing in conjunction with a junk catcher.

a fishing tool used to find and catch wireline in preparation for fishing the line.

n: a formation fluid sampling device, actually run on conductor line rather than wireline, that also logs flow and shut-in pressure in rock near the borehole. A spring mechanism holds a pad finnly against the sidewall while a piston creates a vacuum in a test chamber. Formation fluids enter the test chamber through a valve in the pad. A recorder logs the rate at which the test chamber is filled. Fluids may also be drawn to fill a sampling chamber. Wireline formation tests may be done any number of times during one trip in the hole, so they are very useful in formation testing.

a formation fluid sampling device.

n: a tool used to fish broken wireline out of tubing. Two or three barbed prongs extend along the inside of the Ushaped housing. Wireline becomes caught on these prongs and can be retrieved.

n: any log that is run on wireline.

n: see well logging.

n: A continuous measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations. The record of the measurements, typically a long strip of paper, is also called a log.

n pi: the lowering of mechanical tools, such as valves and fishing tools, into the well for various purposes. Electric wireline operations, such as electric well logging and perforating, involve the use of conductor line, which in the oil patch is commonly but erroneously called wireline.

n: The operation that running all kinds of mechanical tool through wireline.

n: a manually operated ram preventer especially adapted for closure around a wireline.

a BOP for wireline operations.

n: a diagnostic tool used to ascertain the position of a gas leak in the tubing of a gas-lift well.

tools or equipment retrievable with a wireline trip.
