Geologic Modeling, A Vision into the Future

PARADIS, ARTHUR, Dynamic Graphics Inc.

The use of 3D geologic models represents the most exciting prospect for applying computer technology in the oil industry. Three-dimensional modeling technology is rapidly moving from the research lab to the field. Initial results suggest the economic benefits of using 3D models will rival the benefits previously seen from using 3D seismic. Tremendous advancements in 3D model building are expected in the following five areas: 1) Increased speed - Critical time frames must be met for 3D model building technology to be useful. If these time frames are not achieved, the oil industry will ignore the technology. Model building iterations must take minutes to be effective. 2) Usability - Many people need to review modeling results and use their expertise and data to alter the model. To achieve maximum impact, people must be productive after one day’s training. 3) Data integration - Sharing input data and results with other applications make shared earth models a reality. 4) Process integration - The 3D modeling process needs to be coupled with seismic interpretation, well log analysis, reservoir simulation, and reservoir engineering processes. 5) Hardware - Inexpensive, powerful PCs with tremendous graphics capabilities are at the center of future 3D modeling systems.

Visions regarding these five areas will be presented along with two case histories.
