Current Methods and Novel Solutions for Mitigating Lost Circulation

Abstract

Abstract This paper presents novel lost circulation materials that are being developed to address and effectively control moderate to severe lost circulation. We also present a thorough analysis of drilling methods, lost circulation scenarios and current lost mitigation strategies that have to be undertaken when drilling in severe lost circulation zones, which could also improve the probability of success of the novel lost circulation materials to cure losses. Recent development on lost mitigation materials comprising of polymers and fibers is also discussed in detail.
