Berriasian-Hauterivian Shale Sequence and Associated Pinch-Out Trap Prospects of the Yamal Peninsula

Abstract

Based on detailed seismic and well data interpretation, a Berriasian-Early Hauterivian voskhodnaya sequence of shale was distinguished as a part of Akhskaya suite in the south-west of the Yamal Peninsula. Subsequent conventional west dipping clinoforms are pinching-out on the top of the sequence, forming stratigraphic traps, characterized by seismic anomalies. Hydrocarbon prospectivity of the traps is proved by well tests.
