Integration of geophysical data for reservoir modeling and characterization

Abstract

This chapter deals with the integration of geophysical data into the geo-modeling workflow. It starts by introducing the seismic inversion problem and its natural characteristics. Then, we review the most well-known seismic inversion methodologies used among the industry and finally present in detail different geostatistical seismic inversion methodologies. The different methodologies are presented along with its main advantages and the environments where they are most suitable. It describes geostatistical seismic inversion for acoustic and elastic impedances, and density, P-wave and S-wave velocities from pre-stack seismic data. Each methodology presented in this chapter is accompanied along with examples from real case studies.
