The first seismic data across the West Sole gas field were shot during 1962, the field discovery well (48\/6-1) was drilled in 1965 and production well 48\/6-22 and 23 were drilled during 1973. This paper demonstrates the gradual evolution over those eleven years of knowledge of the structural configuration of the field, from the earliest simple time map to the current picture obtained by multilayer, three dimensional migration using sophisticated velocity functions. The formulation of these functions using all available seismic and well information for each of the lithological intervals is discussed, and the overall accuracy of the structural picture is analysed. West Sole is of particular geophysical curiosity because the final depth map on the Base Zechstein bears no direct resemblance for the time map, in fact the shortest reflection times are associated with the deepest part of the feature.
