INFORMATIVE VALUE OF THE PALEOCHANNEL SYSTEMS MORPHOMETRIC ANALYSIS IN THE MIDDLE JURASSIC TYUMEN FORMATION OF THE WEST SIBERIAN OIL AND GAS BASIN WHEN INTERPRETING SEISMIC DATA

The article presents a scientific and methodological approach to assessing the morphometric parameters of the Tyumen Formation paleochannel systems (channel length, valley length, channel formation belt width), which is based on a specialized interpretation of three-dimensional (3D) seismic exploration data. The morphometric parameters of the authors’ program developed in the Python programming language allow calculating the sinuosity coefficient and prediction of paleochannel deposits thickness. The authors recommend this approach for assessing the prospects of paleochannel deposits and further planning of geological exploration.

Keywords: paleochannels, Tyumen Formation, morphometric analysis, sinuosity coefficient, prediction of paleochannel deposits thickness
