A Review of conventional down hole corrosion control methods and selection through judgement tools

The completion design of deep, sour, hot and high pressure gas producers has created some serious material selection challenges to the oil & gas industry through out the world and more specifically in the Middle East region where gas development is a prevalent activity. This paper reviews different options retained by middle East operatorB for well completions & selection of:mstcrials, emerging co:rrosion control methods (such as metallic cladding, ID lining with FRP material), and:finallyprovides basic guidelinC'8 in theselection ofCRA materials. The judgement tools to help defule the most cost effective solution are Life Cycle costing (LCC) per ISO 15663, and a risk assc:ssD1ent matrix of likelihood (of any hazaId) versus consequences. The consequences ofan event will be benchmarkedagainst theoperatorco:rpo:rate policy.
