H038 Automatic Well-to-Well Correlation Based on Consecutive Uncertainty Elimination E.V. Kovalevskiy* (Central Geophysical Expedition JSC) G.N. Gogonenkov (Central Geophysical Expedition JSC) & M.V. Perepechkin (Central Geophysical Expedition JSC) SUMMARY The problem considered is a detailed well-to-well correlation of log data for oil fields with a developed borehole grid. Special software is designed with automatic correlation procedure for log intervals of 60-80 m long as a main part of it. An automatic procedure is based on (1) correlation uncertainty presentation in the form of alternative assumptions and on (2) subsequent algorithm for uncertainty elimination which implements logical reasoning on a triangulation
