Press Release

DALLAS--(BUSINESS WIRE)--Aug. 2, 2001--Landmark Graphics Corp., a wholly owned business unit of Halliburton Company (NYSE:HAL), today announced the opening of the Landmark CAFE(TM) (Collaborative Application Fusion Environment), a new center for collaborative visualization. Located in its Calgary office, the Landmark CAFE represents the latest technology in affordable collaborative visualization software environments.

"The E&P industry in Canada is facing ever increasing complexity in its exploration and exploitation activities," said John Gibson, Landmark's president and CEO. "Landmark Canada recognizes the power of collaborative visualization and has developed the new CAFE with the goal of helping customers lower their finding, lifting and development costs per unit."

The cost of visualization environments has decreased substantially to a point that these facilities no longer have to be customized, restricted to large companies or be applicable to high-cost, high-risk opportunities only. By partnering with SUN Microsystems Inc., the Landmark CAFE utilizes mainstream desktop technology that its clients use daily. The Landmark CAFE confirms that visualization is now reality for a much broader group of users.

"The grand opening of the new Landmark CAFE represents a major investment for the benefit of our customers," added Darcy Cuthill, Landmark Canada's country manager. "We have designed the CAFE with their needs in mind. They will be the big winners by having access to a collaborative visualization environment."

"The center clearly showcases SUN's continued commitment to delivering the high-end graphics performance in the visualization space, including the oil and gas market, at a price point that allows all organizations to take advantage of the technology," said Garry F. Rasko, SUN's regional marketing manager. "By partnering with industry leaders like Landmark Graphics, SUN can ensure that the solutions provided meet today's market place requirements."

To meet its clients' needs, Landmark's collaborative visualization application software is designed to fit directly into and leverage off existing exploration and development workflows. The impact of collaboration and visualization can now be realized by a far broader group than previously thought possible with this type of system.

The Landmark CAFE is now available to all Landmark customers without any facility rental cost, and may be booked by simply contacting Landmark Canada's Calgary office. Landmark's team of professional consultants is available to assist clients in gaining maximum productivity from the CAFE.

Landmark is the leading supplier of integrated E&P technical and economic software solutions, cost-effective Web-based data and application hosting, as well as consulting solutions and services to support decision making in finding, drilling and producing oil and gas. Knowledge-based E&P companies are partnering with Landmark to achieve higher levels of technical-to-business (T2B(TM)) process integration in order to better understand risk management and improve their returns on investment.
