Geo-Logic Systems Chooses INT Toolkit to Build Stratigraphic Interpretation Program

HOUSTON--(BUSINESS WIRE)--March 5, 2002--Geo-Logic Systems, LLC (GLS) is pleased to announce the commercial release of LithoTect, its structural and stratigraphic interpretation program. Built around the latest graphics toolkit components from Interactive Network Technologies (INT), LithoTect is designed to create and validate geological interpretations through restoration and balancing. The LithoTect model construction tools include a complete suite of dip-constrained and general map, profile, well and seismic interpretation methods. Its depth conversion, well monitoring and data projection capabilities are state-of-the-art. The structural restoration/forward modeling techniques include decompaction/isostacy and operate on both interpretations and seismic data -- a unique breakthrough in geological analysis. Major emphasis has been placed on making LithoTect easy to learn and use by all geoscientists. Because it is written in pure Java, LithoTect runs on laptops and workstations of all types.

Also unique to LithoTect is the concept of a ``geometry field'' associated with rock structures, enabling the geoscientist to examine the bedding and distributions of dip, curvature and strain that are implied by their interpretations. The geometry fields automatically incorporate mixtures of influencing elements and combinations of geometric styles (including similar and concentric or angular-bend parallel geometries). They also define the slip systems used for restoration/forward modeling -- with the ability to blend non-constant thickness flexural slip and vertical/oblique slip kinematics.

``For dealing with the real complexities of geological interpretation, or 'uncomplicating the complicated,' LithoTect is the right budget-saving tool,'' said GLS president Jim Geiser. Bob Ratliff, GLS director of product development, added ``The seamless integration of INT software has allowed us to concentrate on the algorithmic and ease-of-use aspects, bringing the dramatic new capabilities of LithoTect's advanced architecture to market in a remarkably short time.''

``Our components are a natural fit for GLS,'' according to INT president Olivier Lhemann. ``This group brings 18 consecutive years of industry expertise, a proven strategy for managing geological complexity, and a strong reputation in the marketplace. LithoTect illustrates the ability to build a complete, sophisticated, user-oriented application interface around the INT graphics toolkits.''

Demonstrations of LithoTect can be seen in the Geo-Logic Systems booth (#1366) during the March 10-13, 2002 AAPG Annual Convention and Exhibition, Houston, Texas.

About the organizations:

Geo-Logic Systems, Inc. was started in 1983 to create the first computerized structural restoration program. Reformed as Geo-Logic Systems, LLC in 1998 and based in Boulder, Colo., the GLS mission is to carry on pioneering work in applications of structural geology to petroleum and minerals exploration and production. The earth modeling application framework of LithoTect -- called EMAF -- is designed to help both the individual specialist and the asset team transform raw data into the geological knowledge from which reasonable reservoir risk can be derived. EMAF is based on an open, collaborative computing architecture, permitting the addition of analysis modules provided by other vendors as well as customers. GLS is on the Internet at www.geologicsystems.com.

INT, Inc. is a software and consulting company based in Houston, specializing in the development of graphics toolkits and graphics intensive applications. INT's data visualization software products enable programmers and vendors working in Java, C++ and C environments to enhance the performance and functionality of their graphics applications while reducing development times and maintenance costs.
