Intetech established a quantitative corrosion model and performed statistical analysis that could be used to estimate the lifespans of all the wells in a mature major oil field.

The results of this comprehensive study fed into field renewal plans. The study included quantitative well-lifespan models and covered the key potential well threats. It formed the basis for planning workover activities and rig requirements. The report also improved the operator’s knowledge of the root causes of certain well integrity threats, helping the analysis of better technical solutions.
