Seismic sedimentology of triassic channel complex in the Barents Sea

The Barents Sea area is located in the Arctic region, categorized as a marginal sea of the Arctic Ocean. The average of water depth is between 230 meters to 1500 meters, bordered by the shelf edge towards the Norwegian Greenland Sea in the West, the Svalbard and the Franz Josef Archipelago in the North, the Novaya Zemlya Archipelago in the East, and Eurasia Continent in the South.Oil and gas activities in the Barents Sea area have been started at 1970 s. Several discoveries already found at that era. In the 1984, Statoil (Norwegian Multinational Oil and Gas Company) made some discovery in the South Barents Sea area, called Snøhvit. In the 2011, Statoil made some significant discovery again in the Barents Sea area, called Skrugard (recently became Johan Castberg). Those significant discoveries are made the exploration activity in the Barents Sea area become more attractive.Geologically, the Barents Sea Area that extends from the Norwegian Greenland Sea to the Novaya Zemlya ridge is covering two major geological provinces (Western Barents Sea and Eastern Barents Sea). Several complex tectonic episodes have been start from Pre-cambrian until Cenozoic time. This tectonic event made a lot of influence in the basin configuration. This thesis will concentrates on the Western Barents Sea area with studying about sedimentological aspect of the reservoir as an objective.Area of interest of the study is located in the Southern Barents Sea (Masøy fault complex). This area (Nucula prospect) is part of two license, production license 393 in the north and exploration license 393B in the south. Nucula prospect has been discovered by 7125/4-1 well in the 2007. Statoil as an operator want to develop the Nucula prospect become commercial. Sedimentology study of the reservoir is needed in order to understand physical behavior of the reservoir. This study will concentrate in the Late Triassic Fruholmen and Snadd formation (Gas & Oil Reservoir). Seismic slicing is the main method in this study.Zone slicing has performed significant result in the seismic interpretation. Fluvial meandering channel has been carried out from the Snadd interval (Wells & Seismic). Fluvial meandering channel on the Snadd interval can divide into two types: Low sinuosity meandering channel and high sinuosity meandering channel.
