Remote Communication and Control of Wellsite Lift Systems

The LiftWatcher Real-Time Surveillance Service provides round-the-clock surveillance of all types of artificial lift systems, enabling you to prevent pump problems or fix them fast.

Surveillance—We watch when you can't.

Our experienced surveillance engineers monitor alarms and alerts 24/7, 365 days a year, at one of many Schlumberger Artificial Lift Surveillance Centers (ALSCs). Data are transferred via satellite to and from remote locations, hostile environments, and sites with limited or no data acquisition capabilities. Where an existing SCADA system is in place, the LiftWatcher system can extract the data and process it with the same top-quality results.

Analysis—Our experience makes the difference.

ALSC engineers review alarm events for all measurements at the wellsite, from motor temperature to continuous flow. They analyze data summaries and poll data on demand. Using Schlumberger best practices and systematic workflows, they identify probable causes, and quickly report remediation options to you for rapid implementation.

Recommendations—We provide critical information fast.

Recommendations are relayed directly to field personnel, who review them via text-messages, e-mail, or a user-friendly Web application. Critical events requiring immediate action to prevent equipment failure are also communicated by phone. When engineers see an opportunity to optimize a well, they can recommend use of the LiftPro Well Optimization Service.
