SLB has introduced its new EWC™ electric well control technology, designed to improve drilling safety while lowering operational costs.

Traditional well control systems rely on complex hydraulic networks of hoses, valves, and actuators. These systems are not only costly to install but also require frequent and expensive maintenance throughout their lifespan.

EWC technology replaces hydraulic systems with a streamlined electric power system, significantly reducing costs while delivering real-time data and continuous power to well control components under all operating conditions.

“As drillers seek safer and more cost-effective well control solutions, we remain committed to innovation,” said Cecilia Prieto, president, Well Construction, SLB.

“EWC represents the next evolution in well control technology, building on our legacy of pioneering advancements such as the industry’s first blowout preventer (BOP) a century ago. These technologies not only eliminate the cost inefficiencies of traditional hydraulic systems but also enhance safety in alignment with global industry standards and regulatory requirements for closing times and full system redundancy,” Prieto added.

EWC technology enables precise, real-time monitoring and control of BOPs for both onshore and offshore operations. By integrating Industrial Internet of Things (IIoT) components, it provides real-time pressure readouts without the need for conventional gauges.

This advancement empowers operators to make more informed decisions regarding well control system operation and maintenance, reducing nonproductive time and minimizing operational expenditures (OPEX), SLB stated on Tuesday.

Additionally, SLB has secured a front-end engineering and design (FEED) contract to develop a customized EWC BOP control system for a rig in the North Sea. The final design review is expected in the first half of 2025.
