Geothermal Drilling Corrosion - Reducing Costs And Failures With Onsite Monitoring And Treatment

摘要

This paper addresses the challenges associated with corrosion as it relates to geothermal drilling activities. Specifically, the common goal is to identify methods to measure the quantitative and qualitative aspects of drilling corrosion in these hostile environments so that appropriate action can be taken to proactively enhance the life of tubulars. Corrosion tendencies will affect drill pipe, downhole tools, surface piping and equipment, and can become a very costly consideration to the drilling contractor and geothermal operator. Onsite testing and monitoring of corrosion can be implemented on a drilling operation. If effective treatment is implemented in a timely manner, then significant operational cost savings can be realized.
