摘要

This paper presents an innovative integrated workflow appliedrnto the characterization of a fractured chalk reservoir in thernDanish North Sea. The methodology uses simultaneousrnintegration of geophysical, geological and engineering data tornproduce an improved reservoir description. Integratingrndynamic flow data with the geophysical and geologicrninformation in 3D, reservoir properties - porosity and effectivernpermeability - are generated using artificial intelligence tools.rnThe strength of this technique lies in the fact that propertyrnmodeling is not constrained to match upscaled well data andrnconsequently these data serve to validate the outcome.rnThis workflow builds upon a methodology that has been usedrnsuccessfully for the characterization of fracture distribution.rnThe technique has been extended to include the generation ofrnseismically derived models of porosity and matrixrnpermeability.The objective of the approach is to improve thernability to capture the heterogeneity of key reservoir properties,rnand thus use the resulting reservoir model to both providernimproved predictive ability and identify previouslyrnundiscovered development opportunities. The application andrnoutcome of this integrated workflow to the Syd Arne field isrnpresented in this paper.
