Time-lapse Seismic - A Multidisciplinary Tool for Reservoir Management on Snorre

Abstract

4D seismic is a very important input to the multidisciplinary work at the Snorre Field. To get most value out of the 4D seismic data it is necessary to establish interpretation strategy and work processes. Both fluid and pressure changes are observed in the 4D seismic data and both differences in seismic amplitudes and timeshifts are used in the interpretation. However, the 4D responses are not unique and it is important to build confidence in the interpretation based on other relevant information as production and injection data, PLT and tracer information.
