Abstract
A-15 THE CASE FOR 4D MONITORING WITH SPARSE OBC Abstract Introduction We seek a better faster cheaper way of performing 4D seismic monitoring to improve reservoir management. We present the case for sparse OBC surveys as a candidate for this. “Better” would be an ability to detect smaller changes due to production and thus make 4D applicable for more fields and to allow earlier spatial diagnosis of production effects. This increased sensitivity depends upon an ability to produce more repeatable data where the subsurface has not changed so that small differences relate to real subsurface effects. This repeatability depends upon
