Comments
The Red Hawk Field is located in Garden Banks Block 877, 160 km (100 miles) from Kerr-McGee’s Gunnison development and 240 km (150 miles) from the Boomvang Nansen developments. Kerr-McGee and Devon hold interests in twenty-seven (27) other blocks in the Red Hawk area which offer additional satellite exploratory opportunities. GB 877 is estimated to have recoverable reserves of 250 bcf of natural gas and will have a peak gross production of 120 mmcf/d of natural gas during the third quarter of 2004.
The Red Hawk Field was developed using new technology: the world’s first cell spar and the second permanent use of synthetic moorings in the Gulf of Mexico. This innovative spar, which is the third generation of spar technology, reduces the reserve threshold needed for an economical development in deep waters.
