Abstract: Integrated Reservoir Description and Flow Performance Evaluation: Glenn Pool Field - Self Unit Study

Asnul Bahar, Leslie G. Thompson, Mohan Kelkar

This paper presents the study of integrated approach to reservoir description as part of the DOE-Class I Projects to improve the oil recovery from a mature oil field. The Self Unit of the Glenn Pool Field (operated by Upland Resources Inc.) was selected as the study area. Geological, geophysical, and engineering information was collected in 160 acre of the Self Unit. An integrated reservoir description was constructed which honors the geological, geophysical, and engineering data using geostatistical (stochastic) as well as the deterministic models. The description was validated by comparing the simulated results with static (well log and well core) as well as dynamic (well test) information.

Both stochastic and deterministic models replicate the geological model very well. The deterministic model predicts an optimistic result whereas the stochastic model follows the field data very well. The incorporation of geophysical information, taken from tomography survey, improves the reservoir description when comparing with the well test information.

Using the description of each models, the flow simulations were conducted to match the historical performance and to predict the future production. Based on the flow simulation and the economic analysis the plan of recompleting the wells and increasing the injection rate was found to be the most feasible to be implemented in the Self Unit to recover more oil.
