Successful Completion of SPT-Shell-HP POSC Pilot Project

Marlow, England, 8th June 1994 – Simon Petroleum Technology (SPT), Shell and Hewlett-Packard announce the successful completion of their Joint Industry Partnership to evaluate the POSC Epicentre data model.

The project involved porting one of SPT's Tigress modules onto the HP Open ODB implementation of the Hybrid Epicentre model and onto an Oracle version of the Relational Projection. A key objective of the project was the practical evaluation of the viability, costs and time-frame associated with deploying Epicentre implementations of existing software. The results will be presented at the POSC Migration Special Interest Group meetings shortly.

Geotechnica Cologne, The Visitors Assessment

With 19,000 trade visitors from 48 countries, including 3,000 from abroad, the second International Trade Fair and Congress for Geosciences and Geotechnology even surpassed the successful premiere of the 1991 event, and according to exhibitors and visitors alike, it particularly proved itself as a "platform" for science, technology and industry.

According to the results of a survey, which was conducted during the event by an independent institute on behalf of KölnMesse, visitors at geotechnica were almost exclusively specialists (99.1 %), and mainly had a scientific (65.6 %) but also a commercial interest (33.5 %). Geotechnica thus fulfilled its purpose as the medium for the interdisciplinary transfer of know-how as well as a marketplace which provided the manufacturers of investment goods for geotechnical applications with a joint forum.

The interdisciplinary nature of geotechnica is underlined by the large number of different geoscientific fields from which visitors came. By far the largest group among the geoscientists was that of the geologists with 44.6 %, followed by geographers (20 %), geophysicists (10.6 %), geodesists (8.4%) and mineralogists (7.1 %). In the other scientific technical fields, engineers accounted for the largest contingent with 46.1 %, 14.6 % were physicists and 7.9 % chemists.

The next geotechnica - International Trade Fair and Congress for Geosciences and Geotechnology – will be held from 2nd to 5th May 1995 in Cologne. Contact numbers:

Employees Take Over Swedish Geophysical Equipment Company

The Swedish company AHEM GeoScience has been taken over by its employees. The new company name is Mala GeoScience and its main line of business will still be the development and production of geophysical measuring equipment.

The company is located in the Northernmost part of Sweden, not more than 200 km from the Arctic Circle, where the development of exploration equipment for base metal ores started as early as in the mid 1920's.

Employees Purchase Landmark/ITA Processing Division, Announce Formation of Integra Geoservices Inc.

Calgary, Alberta, May 5, 1994 - The employees of Landmark Graphics Corporation's ITA Calgary Service Centre today announced their purchase of the 12-year-old seismic data processing business and the formation of a new Calgary-based company, Integra Geoservices Inc.
