Detailed investigation algorithm for hydrocarbons deposits exploration in terms of the Shebelynske gas-condensate field

Abstract

In order to elaborate the neotectonic structure and improve the searching algorithm of new hydrocarbon traps at prospective areas, detailed airspace geological investigation has been carried out. For this study, the selected cross-section Dniprovsko-Donetska depression is the regional seismic profile Lozova-Shebelinka-Staropokrovka within the Shebelinska structure zone.In particular, the investigations consisted of structural and geomorphological analysis, analysis of the hourly seismic profile Lozovaya-Shebelinka-Staropokrovka and analysis of thermal anomalies and structural interpretation by using satellite images. This approach allowed to explore the Shebelinska structure zone and the East-Shebelinska depression for hydrocarbon traps feature properties detecting in Paleozoic sediments.Based on the results of the initial data processing, we established that Paleozoic complex cannot create hydrocarbon deposits, both due to low reservoir properties and due to insufficiently studied structure. Neotectonically, the Shebelinskaya structure looks like a dome-shaped uplift. This uplift is divided by a ravine-gully network into neotectonic blocks. Productive wells are located within the most active blocks.
