There has been a long history of using seismic attributes to estimate net-to-gross or net pay (Brown et al, 1984). The type of approach discussed here employs map-based compensation of tuning effects followed by direct calibration to the reservoir property rather than via an intermediate estimate of absolute impedance. This article describes a process based on band-limited impedance data updated to incorporate more recent advances in inversion and AVO.
