NW Shelf Pressure Study: Australia’s Carnarvon Basin

The Carnarvon Basin contains overpressured Cretaceous, Jurassic and Triassic strata. The uncertainty in understanding the geoPressure regime in the region forms a significant exploration risk for the safe and successful drilling of offshore wells.

As modern exploration targets deeper plays below the region’s Early Cretaceous seals, an increased understanding of geoPressure will be essential to predict overpressure ramps, economically plan wells, and fully understand hydrocarbon migration and trapping.

This NW Shelf Pressure Study seeks to increase the understanding of the pressure regime in the region, therefore improving the safety and success rate in future drilling in this region.

Benefits

• Reduced drilling risk in high pressure drilling with associated time and cost savings
• Potential to increase reserves close to existing facilities, plus new exploration potential
• Improved understanding of the regional pressure regime and its part in controlling aspects of the petroleum system, including trap integrity and reservoir quality

Study carried out in partnership with Woodside Energy and Santos.
