Abstract
Time-lapse (4D) seismic data has been at the heart of the further development of the Gannet F field, from infill well planning, determination of fluid flow and identification of inter-reservoir connectivity. Repeated monitor surveys have allowed an insight into the spatial movement of fluids, even detecting fluid movement in reservoirs with no development well penetrations. Integration of 4D and high-definition 3D seismic inversion results with well data and geological conceptual models have been used to build and test a range of static and dynamic models to investigate connectivity concepts and reservoir distribution. From this improved understanding, the southern reservoir units in the field have been identified as having undeveloped crestal volumes.
