ExxonMobil, an oil and gas company, has drilled and tested the PTU-15 and PTU-16 development wells at the Point Thomson field on Alaska's North Slope.

Point Thomson is a remote natural gas and condensate field located approximately 60 miles east of Prudhoe Bay, and it is estimated to hold about 25% of the North Slope’s discovered gas resources.

The two development wells were drilled to a measured depth of over 16,000ft.

Concurrent with the drilling of the two wells, activities are also focused on engineering and environmental permitting.

To date about $1.5bn, including more than $730m in the last two years, has been invested in Point Thomson.

The Point Thomson project includes gas cycling facilities designed to recover hydrocarbon liquids and re-inject natural gas back into the reservoir.
