Description 329-336
Pre-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.
