Abstract
The development of reservoir qualities during the diagenetic evolution of sand bodies of the Brent Sand Formation in the Viking Graben is described. There are 3 main diagenetic phases: early silicification; strong leaching by circulating fresh waters resulting in kaolinization; and late illitization contemporaneous with the migration of hydrocarbons and associated water. The illitization processes are shown to be more complicated than previously indicated; a source rock outside the Brent Sand Formation is postulated. Analysis of the diagenetic minerals and the pore waters is used to elucidate migration behaviour in reservoirs. Migration is dated as probably occurring during Lower Eocene times.
