Press Release

HOUSTON--(BUSINESS WIRE)--Nov. 8, 2005--GeoGraphix, a brand of the Halliburton (NYSE:HAL) Digital and Consulting Solutions Division and the developer of Discovery(TM) technology, the industry's most integrated and comprehensive Windows(R)-based geoscience interpretation system, is commercially launching its Discovery(TM) on OpenWorks(R) software. Discovery on OpenWorks software directly links GeoGraphix's Discovery software to Landmark's OpenWorks system, the most widely used project data management application in the Exploration and Production (E&P) industry. Landmark Graphics Corporation is a brand of Halliburton Digital and Consulting Solutions Division.

This new technology enhances the efficiency and effectiveness of E&P decision-making processes through better team collaboration and subsurface data management. Geoscientists using Discovery on OpenWorks software can now directly access OpenWorks data and SeisWorks(R) projects without data transfer or replication.

"The Discovery on OpenWorks technology opens up a completely new workflow by enabling E&P professionals to directly access their existing OpenWorks projects using Windows-based tools," said Jonathan Lewis, vice president, Innovation and Marketing, Halliburton Digital and Consulting Solutions. "This technology is a logical next step for asset teams experiencing cumbersome interpretation sharing when working across multiple project or platform environments."

Geologists, geophysicists and IT professionals have estimated that they can spend up to 70 percent of their time moving and synchronizing information between multiple platforms, applications and projects because they lack a common integration environment to facilitate collaboration. The Discovery on OpenWorks system eliminates the time-consuming and error-prone task of maintaining multiple databases by directly communicating with the OpenWorks project environment.

This new technology can be deployed to work directly on the native GeoGraphix project database, the OpenWorks project database or the SeisWorks project database. For geoscience professionals, this means that they can choose the right applications to support their interpretation processes without complicating their project environment.
