Landmark’s OpenWorks® R5000 Software Selected as Part of Chevron’s Next Generation Interpretation Environment

Landmark Software and Services, a product service line of Halliburton’s (NYSE:HAL) Drilling and Evaluation Division, announced today that a major contract was signed with Chevron Energy Technology Company, a Chevron Corporation (NYSE:CVX) subsidiary, for the global deployment of the OpenWorks® R5000 data management system. This solution will be used by more than 1,500 Chevron earth scientists and is a key element of Chevron’s next generation interpretation strategy.

“Chevron’s selection of OpenWorks R5000 software as the foundation for its next generation interpretation environment is a testament to the value clients continue to receive from the OpenWorks application,” said Gene Minnich, vice president, Halliburton Landmark Software and Services. “For the last 15 years we have adhered to the principle of openness, and this has helped position OpenWorks software as the leading project management system in our industry. The commitment to evolving this reliable and secure enterprise class system enables clients such as Chevron to achieve their ongoing business objectives.”

“Chevron continues to make strategic investments in critical information technologies to drive superior performance and growth in our Exploration and Asset Development workflows,” said Jim Green, Chief Information Officer of Chevron Energy Technology. “In developing our next generation interpretation platform, Chevron carefully considered our business requirements, the capabilities available in the upstream data management market and the alignment between the two. The OpenWorks data management solution has been an underlying part of Chevron’s upstream workflows for the past 15 years and we found that today it remains an important component of Chevron’s information technology portfolio.”

Additional capabilities available with the OpenWorks R5000 release such as meta data capture and quality control of seismic data, along with the ability to catalog and manage well data across multiple projects, enables improved data management efficiency within Chevron’s exploration and asset development teams. Open access to the OpenWorks platform for the integration of other vendors and Chevron’s proprietary applications provides the flexibility needed to refine upstream workflows as the build out of the next generation interpretation environment continues.

OpenWorks software is used by more than 12,000 interpreters and 800 E&P companies worldwide. In October 2008, the OpenWorks R5000 release won a World Oil Award in the category of Best Data Management solution.
