SEG Honorary Lecture: Integrating well log, seismic, and CSEM data for reservoir characterization

Well logs provide a high‐resolution measurement of the properties of a reservoir and the surrounding strata; however, properties can only be determined in a small area local to the well. Often measurements of reservoir properties across the extent of a field are desirable for reservoir management or production optimization. Remote geophysical measurements are therefore required. Seismic data are most commonly used for this purpose; however, in recent years CSEM methods, which measure the resistivity structure of the seafloor, have also been widely applied.
