Abstract: Reservoir Modeling and Simulation of the Main Pass 299 Salt Dome, Gulf of Mexico.

Summary

A new comprehensive mapping and 3D earth-modeling project was initiated in June 1996 for Chevron's Main Pass 299 Field. With almost 30 years of production from over 120 wells, an ongoing drilling program is required to maintain current production levels and cash flow. To sustain this program, a better understanding of the reservoirs, and improved efficiency in the new well generation process is required. This is being achieved, in part, by the use of the latest workstation technology in an integrated digital work flow.

Proprietary and vendor workstation software have been used to build a 3D earth-model of the southwest flank of the field. The fault model and horizons were initially interpreted from 3D seismic and well data. The structural framework was transferred to GOCAD++ via ZMAP+, where selected reservoirs were geostatistically populated with geological and petrophysical parameters (e.g.: petrophysical facies, porosity, permeability).

The resultant geostatistical models provided input for reservoir simulation. The simulation provided a model of fluid movement. reserves estimates and production forecasts for proposed wells.

This integrated digital work flow, beginning with the initial seismic and well data. and ending with the reservoir simulation, has reduced well planning cycle time from concept to maturity, and significantly lowered the risk of several wells in the Upper Miocene 7000 Sand Series.
