HOUSTON--(BUSINESS WIRE)--Oct. 1, 2002--

Anadarko breaks new ground by connecting Gulf of Mexico asset teams, data and applications via the Web

Landmark Graphics Corporation, a wholly owned business unit of Halliburton (NYSE:HAL), today announced that they have signed a ground-breaking application and data hosting contract with Anadarko Petroleum Corporation (NYSE:APC).

Anadarko has signed a contract with Landmark to host an integrated suite of seismic and geological software applications, utilities and subsurface data for a deep-water Gulf of Mexico project. This project represents one of the first times that asset teams will work together in real-time from different locations while working on the same data sets and applications hosted in a central site. The contract should provide a competitive advantage for the company, through enhanced virtual teamwork and better leveraging of computing resources. Geographically distributed team members can simply "log on" to the asset from any location with network access and use a powerful, secure, centralized data and applications environment shared by other people working on the same project.

"Landmark is uniquely positioned to increase the effectiveness of Anadarko's exploration project," said Andy Lane, Landmark's president and CEO. "By delivering critical applications and data over the Web, Anadarko will be able to work in ways previously not possible, enhancing their ability to share data and interpretations and communicate knowledge about this deep-water asset more effectively and efficiently within their company. What we're demonstrating in the Halliburton, Landmark and Accenture Real-time Asset Management Center at the 2002 SPE, they are now on the road to implementing. We're excited to be working with them on this breakthrough opportunity."

Utilizing web-based application and data hosting, oil and gas companies can now work together more efficiently on joint venture projects, reduce capital expenditures for an asset, and remove the need to manage rapidly-evolving computer systems through outsourcing data and applications.

"The Gulf of Mexico is an important exploration area for Anadarko and we're continually searching for the best tools and technology that will help us unlock new discoveries," said Jim Emme, Anadarko's vice president, Exploration. "This new technology illustrates how we hope to dramatically improve the way we work together with our partners and share data across the industry in order to overcome the challenges of exploration."
