TGT Oilfield Services has confirmed that its electromagnetic EmPulse® multi-barrier integrity diagnostics system has successfully tested on 28% chromium tubulars, ensuring asset integrity and better well performance in challenging production environments.
In three Middle East deployments – one in which an operator witnessed a ‘yard test’ and the other two in live wells – TGT engineers demonstrated that the EmPulse system can quantitatively determine the individual tubular thickness of up to four concentric barriers, even when there are high amounts of chrome in the tubulars.
Designed and manufactured completely in-house by TGT scientists and engineers, the EmPulse system combines ultra-fast sensor technology with ‘time-domain’ measurement techniques to capture EM signals rapidly and accurately in a wide range of pipe materials, including those with high-chrome content. This enables operators to evaluate pipe thickness and metal loss in multiple casing strings simultaneously, ensuring long-term well performance even in the most challenging production environments.
