Abnormal formation pressures in the Navarin Basin, Bering Sea, Alaska. Final report

Technical Report ·
OSTI ID:5456420
The 75-page report describes and analyzes the occurrences of multiple zones of abnormal formation pressure that were encountered in nine wells drilled in the Navarin basin. The report provides a discussion of the abnormal pressure response on wireline logs and drilling parameters, and a comparison between direct and indirect pressure measurements. The lithology and stratigraphy of the abnormal pressure zones and the wells are based on cuttings and core data. Secondary effects of abnormal pressure such as shale diapirism and in situ stress states and microfracture development are covered. Possible mechanisms of abnormal pressure production and maintenance are also discussed, and a possible evolution of the abnormal pressure zones is proposed.
