Product Overview

To meet the worldwide demand for increased oil production, 4D Technology Inc. offers sophisticated software for improved petroleum exploration and production. 4D seismic technology promises increased oil yields, greater production efficiency, and higher profits for oil companies. This next-generation of production technology adds the fourth dimension: time lapse.

The First 4D Software Tool

4D Technology, Inc. announces the first available 4D software tool to interpret multiple 3D datasets to extract real seismic differences over time. The Lamont 4D Software program, processes multiple 3D seismic surveys for time-sequenced data, updated with well logs and production histories. It provides for the monitoring of past drainage, prediction of future drainage, and calculation of hydrocarbon volumes. The resulting understanding of the hydrodynamic processes within reservoirs improves the performance of reservoir simulators increasing yield and efficiency of oil production.

Improve Yields

How much will 4D technology improve yields? The preceding generation of technology improved oil field yields from 2D's 25% to 30% to 3D's 40% to 50% recovery. BP/Shell's Foenhaven Field reported an expected increase from use of 4D technologies to 65 to 75% recovery efficiency as cited in Petroleum Engineer International, January, 1996.

Review Legacy Data Sets

With the Lamont 4D Rapid Analysis and Inversion Products you can review legacy data sets to find passed over oil and gas for future drilling and improve the initial producing rate. The analysis lets you add infill drilling targets, aids in optimum facility planning (since you neither overbuild nor underbuild), and saves dry holes. Even dissimilar surveys can be analyzed using our correction and normalization processthat includes patented (applied for) 4D seismic.

Future Enhancements Planned

R&D efforts are underway to enhance the capability of this emerging 4D technology. A seismic simulator product will further integrate the Rapid Analysis and Inversion Products which will in turn enhance the predictive control of oil and gas fileds.. The seismic simulator, coupled with reservoir simulation, will allow iteration, enhancing prediction and "what-if" capabilities.

Capabilities of Lamont 4D Software

• Tracks drainage
• Calculates fluid saturation changes
• Enhances determination of:
  • Porosity
