A detailed investigation of the natural fracturing of the North Sea Albuskjell gas-condensate field revealed shear and tension types of fractures through the productive chalk sequences. Theoretical and modeling studies suggest that both fracture types could not have resulted from overpressures alone; seismic studies confirmed that halokinesis was active throughout chalk deposition, creating conditions conducive to fracture formation. Shear fractures are expected to be relatively homogeneous across the field, with a dominant northwest-southeast orientation; tension fractures should be concentrated in crestal areas of the field.
