Neocomian Sequence Zonation in the Rakushechnaya High (North Caspian Offshore)

Summary Three large offshore fields (Filanovskogo, Korchagina, Rakushechnaya) are covered by 3D seismic survey and 18 exploration wells give us important information concerning to sedimentary circumstances in the Neocomian. Sedimentation in two main zones was different and changed in time sequence, besides some transition zone cover the extensive area in the central part of studied high. Main factor was eustatic oscillations of the sea level.
