Due to the high degree of depletion in the Visean deposits, there is a growing need to explore and develop the reserves of the Frasnian-Famennian formation. This interval is characterized by complex geology, which necessitates the application of novel methodological approaches to 3D modeling to reduce geological uncertainties in the structural interpretation of hydrocarbon accumulations. To address this, a new concept for the geological architecture of the Frasnian-Famennian deposits is being implemented for the first time in the N region. This concept is based on seismogeological modeling involving layer-by-layer interpretation of the seismic volume in the depth domain.
The primary objectives of this study are: to develop a methodology for predicting optimal placement of planned well locations based on the construction of a conceptual structural-lithological model of an organogenic genesis field; to reduce uncertainties in the geological framework; and to identify and mitigate the risks of structural misfit during drilling.
