Abstract
The Carpathian Foredeep is one of Ukraine’s principal petroleum provinces, hosting numerous commercial oil and gas fields associated with Mesozoic deposits. The relevance of this study is driven by the need to expand Ukraine’s hydrocarbon resource base and to bring new promising targets into exploration and appraisal, including those associated with Upper Jurassic biohermal buildups. Previous geological and geophysical studies point to the presence, within the Upper Jurassic carbonate complex, of biohermal buildups of various types—from barrier reefs to local bioherms in back-reef facies zones. In a number of cases, such buildups control the occurrence of known hydrocarbon fields (Rudky, Orkhovytshi, Letnia, among others), confirming their high prospectivity. The investigation of the hydrocarbon potential of the Jurassic deposits is based on a comprehensive analysis of deep drilling data, well-logging (industrial geophysics) and paleontological records, the results of lithofacies and hydrodynamic studies, as well as seismic exploration data.
