600 wells connected to espWatcher in 2003

Schlumberger’s hosted submersible pump monitoring service tracks performance via satellite.

Over 600 wells were connected to Schlumberger’s real-time, remote surveillance system for electric submersible pumps, espWatcher (ESPW) in 2003—the largest number of wells monitored with a centralized system of this type. Continuous remote monitoring maximizes well performance, reduces workovers and optimizes lift systems.


ESPW is designed for mature fields with a large number of wells, remote environments or fields where SCADA is limited or unavailable. Pump data interfaces with the ESPW site communication box and real-time data is transmitted via satellite to the Schlumberger-hosted database.


In the event of a problem, alarms and call outs are sent via pager, telephone or email. Thresholds trends and raw data summaries provide information that extends pump life. ESPW leverages Schlumberger’s InterACT real-time monitoring and data delivery technologies and is supported by the Data and Consulting Services unit.
