Joint interpretation of rapid 4D seismic with pressure transient analysis

3D Seismic data interpretation has been traditionally used in reservoir modelling to pick the reservoir top structure and fault detection. Well testing, on the other hand, been mainly used to provide the well / reservoir dynamic properties and the reservoir structures. However there is limited literature published addressing the joint interpretation of the well testing and seismic. Based on synthetic seismic modelling we can delineate the volume of the reservoir affected by well test interpretation and potentially visible in the seismic volume. In this study the architectural framework of a heterogeneous commingled reservoir is illuminated based on the rapid time-lapsed seismic information (4D signals). The methodology discussed in the extended abstract, helps deconvolve the effects of stratigraphic discontinuities and generate a sector-composite map, providing the necessary geological and geophysical constraints, which is then used as a structural framework to be filled with mobility and diffusivity ratios via inverse and forward approaches. This work leads towards the joint testing and seismic imaging to provide improved reservoir description.© 2010, Society of Petroleum Engineers.
