Reservoir Surveillance Technologies for Thermal EOR Projects

Shell has started to launch integrated data acquisition programs and to test automated methods for<br>optimizing injection and production schedules in thermal EOR projects. We present applications of a suite<br>of areal and well-based reservoir surveillance technologies to thermal hydrocarbon recovery in the<br>Canadian heavy-oil sands and the Middle East. These technologies include surface seismic, micro seismic,<br>downhole seismic, and are combined with forward and inverse modeling in an effort to improve reservoir<br>understanding and to optimize production.
