Downhole corrosion
WebMar 13, 2011 · ABSTRACT:. Corrosion of downhole tubulars can be a serious concern when the produced crude has a high water cut (greater than15 to 20%) and a CO2 content of a few percent. Two options are available for corrosion control: (a) use of a suitable corrosion inhibitor inside the tubing, or (b) use of a suitable corrosion resistant alloy … Web1. Corrosion Concerns While Drilling Geothermal Wells include: • Downhole tooling corrosion – Downhole pipe and tooling fatigue and failure might be observed as severe pitting of drill pipe, washouts, twist-offs at tool joints, catastrophic drill string failures, stress cracking of drill pipe, damage to directional tools and

WebJan 1, 2024 · Downhole corrosion coupons or probes are offered by corrosion-monitoring companies, but these require wireline access to retrieve and usually special fittings downhole. Furthermore, because corrosion may vary at different depths in the well, downhole monitoring is best achieved by multiple locations up the string, which …
WebECE® is a tool that assists corrosion engineers through the quantitative estimation of corrosion rates and selection of corrosion-resistant materials. At the heart of ECE is a model for corrosion analysis, firmly based on laboratory data and on-field calibration studies with pipelines, piping and downhole tubing.
