Re-evaluation of the Norwegian Side of the North Sea for Post-Rift Hydrocarbon Plays and Undiscovered Stratigraphic Traps.

The focus of this study is to re-evaluate the post-rift petroleum rich plays of the Norwegian North Sea. Undiscovered stratigraphic traps are expected to be found in the Norwegian North Sea that are analogous to those of the United Kingdom post-rift sections. It is proposed to extrapolate information from discovered stratigraphic traps in the study area in order to explore whole sequences that may have been missed and discover more subtle petroleum traps. The petroleum companies have explored and started production in plays of well-known stratigraphic traps related to the Highstand Sequence Set (HSS) and the Transgressive Sequence Set (TSS) while the Lowstand Sequence Set (LSS) is still undiscovered.  The main objective of this study is to determine the maturity of the important post-rift hydrocarbon plays in the Norwegian North Sea and to discover missed stratigraphic/ structural plays and traps. 2D and 3D seismic data and well logs are available for the selected potential plays along with stratigraphic interpretations, final reports, and core images. The Software that will be used for data analysis include the Schlumberger Petrel and Veritas Hampson-Russell. The methodology implemented will include (1) field size distribution analysis for the selected plays, (2) seismic interpretation, (3) delineation of mega-sequence boundaries, (4) evaluation of the trapping potential within mega-sequence boundaries, (5) compilation of subcrop and supercrop maps down to the Lower Cretaceous Unconformity (LCU), (6) compilation of gross depositional environment map for each newly identified sequence, and (7) amplitude vs. offset (AVO) and risk analysis
