HOUSTON--(BUSINESS WIRE)--June 21, 2001

GeoQuest, the software division of Schlumberger Oil & Gas Information Solutions (SIS), announced today that it received Support Center Practices (SCP) Certification for delivering exceptional customer support to its software clients. This is the third consecutive year GeoQuest has achieved this exceptional ranking, which quantifies the effectiveness of customer support centers based upon a set of stringent performance standards and represents best practices in the industry.

"World-class support has been one of our distinguishing characteristics since our beginning," said Satish Pai, president of SIS. "This recognition proves again that our customers can count on us to be there when they need us. At GeoQuest, we continuously strive to enhance our services and today we are proud to offer innovative Web-based support to our customers, in addition to our well established local presence."

This third consecutive SCP Certification comes just a few months after GeoQuest won its second consecutive Software Technical Assistance Recognition (STAR) Award, recognizing customer service excellence among software support professionals. GeoQuest is the only company in the oil and gas industry to ever win a STAR Award, a coveted prize since the Software Support Professionals Association (SSPA) established the program in 1990. SSPA also is responsible for SCP Certification.

"GeoQuest continues to demonstrate an outstanding commitment to quality service. This commitment is clearly demonstrated through the extremely high customer satisfaction levels seen during SCP Certification audits over the previous three years," said Greg Coleman, principal and vice president of Certification for Service Strategies Corporation. "The company has demonstrated an outstanding level of consistency and is clearly committed to employing best practices within customer support, as evidenced through attainment of SCP Certification for the third consecutive year."

GeoQuest is among the ranks of other leading technology companies that have achieved SCP Certification, including Intuit Inc., Lockheed Martin Inc., Lucent Technologies, Silicon Graphics Inc. and Xerox Corporation.

SCP auditors conduct comprehensive on-site audits to evaluate whether or not companies meet the requirements of over 100 business elements defined in the program. SCP certification measures factors such as corporate commitment and strategic direction, customer satisfaction, performance metrics, research and development interface, and other strategic areas of the support operation. Certified companies must continue to demonstrate their commitment to excellence and high performance standards through annual recertification audits.
