n: a thermosetting resin made from the by-product of the carbonisation of bituminous coal. It is used as a coating because of its adhesiveness, flexibility, and resistance to chemicals.

n: 1. any compound characterized by the presence of a reactive chemical structure that has an oxygen atom joined to each of two carbon atoms that are already bonded.2. any of various resins capable of forming tight cross-linked polymer structures characterized by toughness, strong adhesion, and high corrosion and chemical resistance. Epoxys are used extensively as coatings and adhesives.

a resin formed by reaction of polyols with epichlorohydrin.

n: a powdered resin coating that forms a skin over pipe when applied to its heated steel surface. Usually applied at the mill.

n: a stressed-steel corrugated tube that is lowered into existing casing in a well to repair a hole or leak in the casing. The patch is cemented to the casing with glass fibre and epoxy resin.

n: A downhole assembly or tool system used in the remedial repair of casing damage, corrosion or leaks. Casing patches are most frequently used as short- to medium-term repairs that enable production to be resumed until a major workover operation is schedule

n: a special material that coats pipe for pipelines and prevents water from coming into contact with the steel of the pipe. The most widely used types of pipe coatings are bituminous enamels, epoxy resins, and tapes.

n: anyone of several methods by which the loose, unconsolidated grains of a producing formation are made to adhere to prevent a well from producing sand but pemlit it to produce oil and gas.

one of various methods of consolidating the grains of an unconsolidated or weakly consolidated formation. Typically resin consolidation (epoxy, furan or phenol-formaldehyde),but may also include sodium silicate, coking, and mineral or metal precipitates.

a section of the formation, forcibly impregnated with epoxy and sliced thin enough to examine with a light from the opposite side.
