The Upper Jurassic (Kimmeridgian-Tithonian) Lourinhã Formation of the Lusitanian Basin, Portugal, contains over one thousand meters of stratigraphy. Excellent outcrops allow collection of Previous HitfieldNext Hit Previous HitdataNext Hit to assist in understanding the fluvial-dominated Statfjord Formation in the Tampen Spur area of the Norwegian North Sea. Three years of outcrop Previous HitdataNext Hit collection has produced a substantial database, the analysis of which can be used to more accurately model the variations in reservoir properties in these types of reservoirs.

A Previous HitfieldNext Hit Previous HitdataNext Hit collection methodology has been devised to allow systematic recording of both qualitative and quantitative sand-body observations and interpretations that can be more easily utilised in multi-scale modelling studies. These scaled models are used to increase our understanding of the lithofacies, internal architectural elements and associated heterogeneities within fluvial sandbodies that are often not represented within Previous HitfieldNext Hit-scale subsurface modelling studies. Previous HitExamplesNext Hit of such Previous HitdataNext Hit includes 1:10 and 1:50 scale Previous HitfieldNext Hit logs, channel body scale correlation (10s of metres) and channel belt scale dimensional properties. All scales of Previous HitdataNext Hit have been loaded into an ODM3 database for presentation and database management, and to a SpotFire database where statistical analyses of the various Previous HitdataNext Hit types were undertaken. Traditional Previous HitfieldNext Hit Previous HitdataNext Hit has been supplemented with the collection of LiDAR Previous HitdataNext Hit and the incorporation of Digital Terrain Models.

The ‘Pore-to-Previous HitFieldNext Hit’ modelling concept has been utilised, creating multi-scale representations of these outcrop Previous HitdataNext Hit. SBED™ and SBEDStudio™ have been used to model lithofacies and facies association scale Previous HitdataNext Hit, which have then been incorporated into Previous HitfieldTop-scale reservoir models for direct comparison to the subsurface modelling of the Statfjord Formation.
