2 Onshore UK Field Training Courses Why the UK? UK geology is unique in the world with Precambrian to Tertiary sediments well represented and many type sections the home of geology North Sea exploration has led to the discovery and production of oil & gas from a diverse range of structural styles and sedimentary basins, many of these basin types are represented in UK onshore areas Devonian fluvial sands (mainly outer Moray Firth fields) Carboniferous deltaic channel sands (Southern Gas Basin fields) Permian aeolian and fluvial sands (Southern Gas Basin fields) Triassic fluvial sands (Central/Northern North Sea and Barents Sea fields) Middle Jurassic deltaics (Northern North Sea fields) Ur Jurassic paralic to shallow marine sands (mainly Outer Moray Firth, Central North Sea fields) Ur Jurassic submarine fans (Northern North Sea, Central North Sea, as well as Palaeocene and Eocene fields) World class source rocks Kimmeridge Clay and Lr Jurassic shales Carboniferous Westphalian coals Locations (see following map) Beautiful countryside, principal locations include: Dorset (Jurassic Coast, World Heritage Site) Moray Firth Yorkshire coast

4 Why Attend Field Courses? Real geology Review basic and advanced sedimentology Identification of sedimentary environments Understand sedimentary processes Sand body geometry micro and macro scale Essential for understanding petroleum systems Oil & gas fields Better understanding of field data, particularly core interpretation Appreciate the issues surrounding reservoir facies and quality Geological input for seismic attribute studies Exploration North Sea application Stratigraphy and stratigraphic concepts Essential input for seismic stratigraphy and seismic attribute studies Structural geology Distribution of reservoir formations Source rock studies
