Improved Understanding of Deep Tight Gas Reservoirs with Evolving Seismic Reprocessing: A Case Study from an Offshore Field in Abu Dhabi

K.A. Obaid1, F. Neves1, and M. Mahgoub1



A 3D OBC seismic data of an offshore field in Abu Dhabi was subjected to different and increasing levels of in-house seismic reprocessing. The evolution of the reprocessing effort started from the refinement of legacy data by Post-stack seismic reprocessing (PSR), moving to Pre-stack seismic reprocessing (PreSR) using as input raw field data and adopting state-of-art processing workflow. The objective was to improve the structural and stratigraphic seismic interpretation of the deep Paleozoic tight gas reservoirs.
