Comparison of deterministic and geostatistical inversion results - a case study for a gas saturated clastic reservoir with thin coal beds
Back to Technical ContentIn this paper a comparison of deterministic and geostatistical inversion approaches to reservoir characterization of a complex gas saturated clastic reservoir with thin coal beds will be discussed. This type of reservoir is characterized by high acoustic contrasts which cause challenges for inversion techniques. To overcome these challenges in deterministic inversion a methodology was applied to update the low frequency model in an iterative manner. This improves the accuracy of elastic properties prediction and, therefore resulting in a more reliable reservoir model, which was verified with data from 28 newly drilled wells.
