Borehole time-lapse seismic tracks steam flood: Borehole seismic can deliver a higher resolution than surface methods to solve critical EOR issues

摘要

Time-lapse methods are becoming increasingly useful in understanding reservoir dynamics. Any parameter that changes slowly over time can be studied by comparing sequential measurements. These measurements may be made in wells or remotely on the surface and can provide useful information to update reservoir models used to manage a field. Particularly successful offshore, time-lapse surface seismic, popularly called 4-D, provides an example of such remote measurements that have matured into a commonly used technique.
