Halliburton launches automated continuous circulation system

Halliburton released the e-cd Plus system – a new technology that automates and enhances continuous circulation connections during drilling and tripping operations. Continuous circulation provides the uninterrupted flow of drilling fluid into the well throughout the process of adding or removing drillpipe joints to the drillstring.

On a recent project in the North Sea, an operator was previously unable to successfully reach target depth due to poor cuttings movement and wellbore stress. They deployed the automated diversion portion of the e-cd Plus system to provide continuous circulation over two well sections and approximately 6,800 ft of total open-hole drilling. The operator successfully reached total depth and cemented the liner in each section, helping eliminate the challenges that halted operation in the previous offset well.
