| Popis: |
It is suggested to acquire frequent low cost seismic data over a field equipped with a permanent receiver system. The source pattern could be one or two permanent sources located on platforms, or 3-5 2D shooting lines covering the field. Modeling examples showing the feasibility of both acquisiton methods and their ability to detect for instance gas leakage or overburden velocity changes caused by geomechanical changes will be presented. Most producing hydrocarbon reservoirs will compact, and therefore corresponding sea floor subsidence is expected. We propose to use time lapse tilt meter readings from a dense permanent array to estimate seafloor subsidence. We suggest to combine tilt meter measurements with sparse permanent pressure sensors located at the seabed. |
