Schlumberger and Infosys Announce Global Alliance for Exploration & Production Information Management; Combined Strengths Provide End-to-End Information Management Solutions.

PARIS -- Schlumberger and Infosys (NASDAQ:INFY) announced today that they have formed a global alliance to provide comprehensive information management solutions that integrate upstream technical and business processes for oil and gas companies.

The alliance will address a wide array of solutions, primarily focused on the integration of E&P petrotechnical data and applications, including unstructured data, with financial and human resources back-end systems, in order to streamline operational and strategic business decision-making processes.

"Our customers are under tremendous pressure to accelerate their production and replace reserves. To achieve results, operators are looking at ways to reengineer their technical and business processes," said Olivier Le Peuch, President, Schlumberger Information Solutions. "By aligning with Infosys, Schlumberger brings customers a much needed combination of technology, domain expertise, and systems integration capability -- on a global, enterprise scale."

This alliance combines the market leading exploration and production (E&P) domain expertise of Schlumberger with the Global Delivery Model (GDM) pioneered by the Infosys organization to create an industry unique resource. Infosys' GDM reduces engagement risk as it takes work where it can be done best, makes the most economic sense, with the least amount of risk.

"Schlumberger is the leader in delivering breakthrough solutions to the upstream oil and gas industry," said Naren Koduvattat, Head of Infosys' Energy Business Unit. "Infosys is at the leading edge of designing and delivering IT-enabled business solutions to oil and gas companies, and our combined expertise will deliver powerful solutions to the E&P industry. Our alliance will provide end-to-end solutions integrating petrotechnical data with other relevant business systems, which is atypical in the market today."

Infosys and Schlumberger will build on the successful working relationship the two organizations have developed over the last several years. "Using comprehensive information management solutions supported by expert system integration services, oil and gas companies can increase productivity, better leverage their IT investments and enhance the effectiveness of operational processes," said Le Peuch.
