Exploration
Appraisal of the Willow Discovery in the Bear Tooth Unit in the National Petroleum Reserve-Alaska (NPR-A)
continued with the drilling of two of four planned appraisal wells before the early cancellation of the 2020
program as part of our COVID-19 response. The reduced 2020 appraisal program consisted of drilling a
horizontal well in the eastern portion of the field, informing the reservoir’s connectivity, and a vertical well in
the field’s southern extent, reducing the original oil in place uncertainty. The initial development plan for the
Willow Discovery, approved in the fourth quarter, does not include the Cassin Discovery from 2013; therefore,
we recognized dry hole expense for two previously suspended Cassin wells in 2020.
In 2020, exploration of the Harpoon Complex—Harpoon, Lower Harpoon and West Harpoon—commenced.
One exploration well of a planned three-well program was drilled before the early cancellation of our 2020
winter drilling season in response to COVID-19. The well was expensed as a dry hole after evaluations
confirmed the well intersected sub-commercial volumes of hydrocarbons in the upper Harpoon interval which
will not be developed. Future exploration plans include returning to the Harpoon Complex to explore the
remaining potential.
