| Popis: |
It is quite common for mature North Sea fields to be producing significant volumes but infill drilling may be using maps made on survey data which is over a decade old. New acquisition has been common where the reservoirs are acoustically favourable to time-lapse (4D) studies but in many fields new acquisition is often thought to be unjustifiable based on cost and a perceived stagnation in the continued improvement in acquisition quality. New understanding of the value of azimuthally diverse information has undoubtedly brought a step change in image quality to sub-salt reservoir delineation. In this paper we use 3D elastic modelling to try and decide whether different acquisition geometries may bring similar benefits to North Sea imaging, multiple suppression, and reservoir characterization. |
