APPLIED RESERVOIR GEOLOGY • Introduction • Definitions, principles • Case examples • North Sea, Statfjord Field • Sedimentology • Review • Well log interpretation (lithology identification, log patterns1, 2) • Core descriptions, well-to-well facies interpolations3 • Stratigraphy and Reservoir Zonation • Lithostratigraphy versus sequence stratigraphy4, 5 • Examples of reservoir zonations6 (ie. Raude Mbr. on Statfjord, Hugin Fm. on Sleipner) • Applied Reservoir Geology • Targeting Remaining Oil • Well Planning / Drilling • Well Interventions Exercise 1: interpret the Brent formations in well 33/9-A-31 Exercise 2: identify the main Ness sandstones and interpret facies (wells A-31 and B-26) Exercise 3: correlate the Ness sandstones from well to well (facies interpolation) Exercise 4: identify the main lithostratigraphic units (formations) for Lower Brent Exercise 5: find the stratigraphic sequences in each well and correlate them Exercise 6: zone the Raude Member from well logs
