Application of quantitative sedimentology in the characterization of subsurface reservoirs and outcrop analogs

摘要

The thesis deals with methods of describing the reservoir rock in central oil and gas fields on the Norwegian continental shelf. Methods of enhancing the level of recovery are dealt with. Following topics are given: Sand body dimensions and infill sequences of stable, humid-climate delta plain channels; minipermeameter-based study of permeability trends in channel sand bodies; significance of tidal cyclicity for modelling of reservoir heterogeneities in the lower Jurassic Tilje Formation, mid-Norwegian shelf; geometry and facies of large-scale flow units in fluvial-dominated fan-delta-front sequences; quantified fluvial architecture in ephemeral stream deposits of the Esplugafreda Formation (Palaeocene), Tremp-Graus Basin, northern Spain; the Safari project - collection and storage of field analogue data for quantitative reservoir modelling; sedimentary architecture of field analogues for reservoir information (SAFARI): a case study of the fluvial Escanilla Formation, Spanish Pyrenees; facies analysis and high-resolution sequence stratigraphy of the lower Eocene shallow marine Ametlla Formation, Spanish Pyrenees; architecture of an unconformity-based tidal sandstone unit in the Ametlla Formation, Spanish Pyrenees; reservoir architecture of the Cook Formation on the Gullfaks Field based on sequence stratigraphic concepts. 342 refs., 149 figs., 16 tabs.
