n: the technique for covering a completed pipeline so that adequate fill materal is provided underneath the pipe as well as above it. Backfilling prevents pipe damage caused by loose rock, abrasion, shifting, and washouts.
n: a record showing variations in wellbore diameter by depth, indicating undue enlargement due to caving in, washout, or other causes. The caliper log also reveals corrosion, scaling, or pitting inside tubular goods.
n: A tool run on wireline that measures the diameter of the wellbore. It may be used for detecting washouts, calculating cement volumes, or detecting internal corrosion of casing.
a recording of the diameter changes in a well made by a tool with mechanical arms that touch the wellbore or a sonic signal bouncing off the borehole wall.

n: a device that divides a ditch into sections to form internal barriers to water movement. Ditch breakers are used for pipelines in areas where washouts are a threat.
n: the method to find the position on the drilling pipe where the hole should be drilled
the diameter of the bit of the hole drilled by the bit when there are no washouts.
n: A wellbore that is essentially the same diameter as the bit that was used to drill it. It is common to find well-consolidated sandstones and carbonate rocks that remain gauge after being drilled. For clays, it is common for the hole to slowly enlarge with
a drilled hole with no washouts;the same diameter as the bit.
n: the phenomenon of the wellhore enlarged by the flush of drillfluid .
a wellbore caliper, useful in larger wellbores and washouts that uses sound through thin liquids to map the wellbore.
n: 1. excessive wellbore enlargement caused by solvent and erosional action of the drilling fluid. 2. a fluidcut opening caused by fluid leakage.
flow cutting of equipment downhole.
