Abstract

Summary

The Jade Field, located the Central graben of the North Sea, has over 1Tcf of gas trapped within the Skagerrak Formation. Multiple fluid compartments are present and controlled by hydrodynamic fault seals. Overpressures reduce from the down-faulted flanks to the central horst in the field, with aquifer pressure steps of up to 115 bar developed across the bounding faults. This large overpressure step has affected how the gas condensate is trapped within the field. In the Central horst the bounding faults create hydraulic resistance seals allowing a 3500ft (1100m) column to be trapped. On the flanks the hydrodynamic fault seals trapped significantly smaller columns (600–800ft) (200–250m). The data acquired through appraisal and development drilling allows the plumbing history of the field to be elucidated and enables fault seal calibration to be attempted.
