Abstract
Summary
We present a case study where a new seismic dataset’s improved data quality has enabled a geologically-constrained Bayesian pre-stack inversion algorithm to produce reliable and usable inversion results to uncover significant pockets of oil. The chosen inversion methodology was PCube+: A Bayesian algorithm that uses a local neighborhood approach to perform a one-step inversion to lithology-fluid classes. By using the resulting sand map together with production and well data, areas with remaining reserves can be identified for infill drilling. One such area that was identified led to the drilling of an oil producer that is one of the best performing wells on the Statfjord field in years.
