dc.description.abstractPre-Caspian basin has been formed from Paleozoic to Cenozoic time and the Kashagan field is situated in the southern part of Pre-Caspian depression in the Southern flung of Astrakhan-Aktyubinsk elevation system of basal complex and associated with Tengiz-Kashagan interbasin carbonate platform. Platform is composed of separate carbonate early Carboniferous blocks resting on the common Devonian (late Fransian-Fammenian) carbonate base. Four of them are: Kashagan, Kashagan South-West, Aktote and Kairan are located on the Caspian shelf and Karaton, Tengiz and Korolev on the coastal line of the eastern Caspian. Depositions of Devonian through to Elephantine inclusive were penetrated in Kashagan. Maximum section penetrated during drilling was 5172 m in KE-1. Pre-salt and post-salt units separated by thick Kungurian of Lower Permian salt-bearing section were identified in the well log. Description of the tectonics of the field was based on 3D seismic and drilling data from КЕ-1, КЕ-2, КЕ-3, КЕ-5 for East Kashagan and 2D seismic for West Kashagan where one well KW-1 was drilled. 3D seismic data provided more detailed information about geology of the structure, facies distribution and main layer thicknesses, and allowed a more accurate interpretation of tectonic faulting.en_US
