We present in this paper a geostatistical methodology to incorporate additional low frequency and low‐resolution information derived from velocity analysis. The resulting acoustic impedance model is then better constrained in the inter‐well space, particularly in the case where only few wells are available. Consequently, the acoustic impedance model obtained by stratigraphic inversion gains in reliability, which we will illustrate on a real case example from an offshore North Sea field.Permalink: https://doi.org/10.1190/1.1839678FiguresReferencesRelatedDetailsCited ByDouble-scale supervised inversion with a data-driven forward model for low-frequency impedance recoverySanyi Yuan, Xinqi Jiao, Yaneng Luo, Wenjing Sang, and Shangxu Wang27 December 2021 | GEOPHYSICS, Vol. 87, No. 2Cooperative joint inversion of 3D seismic and magnetotelluric data: With application in a mineral provinceEric M.
