Technology reduces risk and increases efficiency
HOUSTON – April 18, 2018 – Halliburton (NYSE: HAL) today 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 drill pipe joints to the
After connecting the e-cd Plus system to surface control equipment, a proprietary software remotely
controls all steps of the flow diversion and side port connection process that is currently completed
via manual human operation. The overall system maintains a small footprint and can reduce the number of
rig personnel required to safely provide continuous downhole circulation.
The system also helps improve success in challenging projects such as wells with narrow pore
pressure/fracture gradients by keeping bottom-hole pressure and fluid properties constant, cooling
equipment in high-pressure and high temperature applications and providing continuous wellbore cleaning
by movement of cuttings in extended reach wells.
"We designed the e-cd Plus system to meet the growing market demand for continuous circulation
technology in highly regulated markets by improving safety, efficiency and reducing overall connection
time to save valuable rig time," said Daniel Casale, vice president of Testing and Subsea. "With the
automated system, not only is a dual pressure barrier maintained during operations, but it has the
versatility to run either as a standalone solution or to be used in managed pressure drilling
operations to help reduce risk in difficult wells."
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 feet 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
