SchlumbergerSema joins forces with Tasnet to provide substation automation to utility customers

DENVER, Colo., March 4, 2002 — SchlumbergerSema, a business unit of Schlumberger Limited, has announced the addition of substation automation services to its Digital Energy Enterprise offering.

Working with technology from Tasnet, SchlumbergerSema now provides solutions for controlling substations through substation integration, which involves the collection of data from IEDs (Intelligent Electronic Devices) within a substation.

This enables the utility to quickly make accurate decisions aimed at improving the quality of service provided to the end customer. Data is stored in an “open” database, allowing PLC (Programmable Logic Controller), SCADA (Supervisory Control and Data Acquisition), WAN (wide area network), local and remote users direct access for immediate substation control. Substation automation plays a critical role in the digital enablement of the transport network.

It provides a foundation layer for delivering critical information to the utility knowledge infrastructure and bringing additional, essential real-time information into the community. This enables better resolution of capacity management and commodity access issues. System solutions are based on readily available Intel-based computers and PLC platforms. Configuration can easily tailor information, supplying the right information to the correct individuals while maintaining required security information from others.

“We are committed to this market segment,” stated Ivo Steklac, SchlumbergerSema vice president of Marketing and Business Development. “Our vision of the Energy Information Community enables the creation of a more efficient marketplace by bringing services and technologies to all participants in the energy value chain — from producers to consumers.”

“Tasnet’s open substation automation architecture and related implementation services complement the Energy Information Community vision of SchlumbergerSema by enabling utilities to bring ‘on-line’ vast amounts of information essential to the optimum operation of energy networks,” said Steve Baker, vice president of Tasnet. “Our combined mutual capabilities can now bring efficiencies and benefits that were previously unobtainable to the market.”

“Together, SchlumbergerSema and Tasnet provide a combination of superior proven technology and strong technical support with our expertise in large project and system integration skills,” stated Brad Kitterman, SchlumbergerSema Energy and Utilities president, North America.
