Sour Weld Corrosion Mitigation with a Low Dose Inhibitor

Preferential weld corrosion offers a uniquely different mitigation challenge to operators of high throughput oilfield production in carbon steel pipelines. This has a significant impact on the expected lifetime of the pipeline and thus will require chemical inhibition programs to control such localized corrosion effects. As a part of OPEX these programs require field optimization whilst providing the desired level of corrosion protection at minimum inhibitor dose rate.A low dose corrosion inhibitor has been developed that inhibits sour corrosion of individual weld components of pre-corroded steel coupons prepared from pipeline material. Metallurgical analysis of the weld section extracted from the pipeline was performed which illustrated unusual composition of the material.The lower corrosion inhibitor dose also reduces the influence of secondary effects (including emulsion and foaming) eliminating the need for specialized formulation additives and the injection of additional chemistries. Due to the low water cut and the stratified flow regime of a subsea pipeline the partitioning behavior of the product was an important consideration during product development. Since the treatment of bacteria in the pipeline was necessary the compatibility of the inhibitor with the incumbent biocide was critical.This paper details the test work performed to develop a new inhibitor to prevent weld corrosion under sour conditions. The inhibitor was evaluated in numerous performance under including kettle tests high pressure autoclaves partitioning and autoclave weldment corrosion tests.
