Abstract

Seismic reservoir monitoring is gaining popularity within the Exploration and Producing industry. Analysis of repetitive seismic surveys provides direct measurements of the fluid movements and saturation changes within the hydrocarbon accumulation. Tracking saturation fronts is essential to design and improve depletion and production strategies in order to properly manage as well as predict the performance of the field. In this paper, we present the analysis and results of a seismic reservoir monitoring project over an offshore clastic field in the Arabian Gulf. After rotation and repositioning of the two seismic datasets, a difference 3D volume was computed, validated by geological data and calibrated to a reservoir simulation model that has been history matched. The seismic difference between the two 3D surveys indicates gas encroachment within the upper part of the reservoir and is in overall agreement with production logging measurements at the wells.
