Squeezed Diapirs of the Timan Pechora Basin: Structure, Evolution and Petroleum Prospectivity

Over the last two decades the frontal part of the fold and thrust belt in the northeastern part of the Timan Pechora basin attracted considerable interest of oil industry. Nevertheless, significant exploration efforts so far have failed to deliver significant volume of hydrocarbons. Review of the past exploration indicated that majority of the wells failed due to misinterpretation of structural setting and evolution of petroleum systems. Many dry holes were targeted late or postmigrational traps. This study included reprocessing and reinterpretation of vintage and newly available data which provided new insight into structural framework of the fold and thrust belt. The updated interpretation shows new exiting opportunities for petroleum exploration provided by subsalt traps.
