Reliable corrosion inhibition in the oil and gas industry

The objective of the work was to undertake a literature review on the subject of corrosion inhibition in the offshore oil and gas industry to understand the current issues. The application of chemical corrosion inhibitors can significantly reduce the rate of corrosion of carbon steel pipelines due to the presence of CO2 and/or H2S.

BONDSTRAND™ - NOV Inc.

Historically, offshore production platform, drilling rig and FPSO owners and operators have had to face the grim reality of continuously replacing most metal piping because of severe corrosion. This has resulted in piping systems costing two or three times the original investment since steel and metal pipe systems are very costly to maintain.
