Using full-azimuth imaging and inversion in a Belarus salt dome tectonic regime to analyze fracturing in Upper Devonian intersalt and subsalt carbonate reservoirs

摘要

An analysis of recent publications, together with the results of the European Association of Geoscientists & Engineers (EAGE) and EurAsian Geophysical Society (EAGO) exhibitions, reveals an unequivocal trend towards an increase in information content and accuracy of fracture predictions made using full-azimuth seismic acquisition and processing technology. This trend is notable in oil and gas fields in carbonate and terrigenous reservoirs within the countries of the Commonwealth of Independent States (CIS), where major oil companies such as Gazprom, Gazpromneft, Lukoil, Novatek, etc., are already conducting work of this type. This trend has also been observed abroad, but on a larger scale. The number of successfully completed projects is sufficient to confirm a surge in the use of higher density and richer seismic azimuth surveys in the coming decades.
