Gas Hydrates
commonly occur in Arctic regions and
deep ocean continental margins.
is a crystalline substance composed
of water and methane gas.
The solid water lattice accommodates gas
molecules in a cage-like structure.
One cu. ft. of methane hydrate will contain
as much as 180 cu. ft. of gas.
represent a large world wide resource,
500 to 1,200,000 tcf of gas.
North Slope Gas Hydrates
were confirmed in 1972 at N. W. Eileen
with cores and tests.
overlie the eastern part of Kuparuk Field
and the western part of Prudhoe Bay Field.
occur in the Tertiary Sagavanirktok
Formation (Ugnu sands).
occur between depths of 700 and 3000 feet
with free gas below 3000 feet.
reserves range from 37 to 44 tcf (15 times
that contained in the Messoyakha Field).
Free gas reserves estimated at about 1 tcf.
Geologic conditions being similar to those
at the Messoyakha Field suggests Alaskan
gas hydrates may also be producible.

COAL BASINS and
OCCURRENCES
After Merritt and Hawley, 1986
Alaska contains
nearly 1/2 of the United States coal reserves
or hypothetical resources that exceed
5.5 trillion short tons
Alaska’s Coals
Are mostly Cretaceous and Tertiary in age.
Underlie about 9% of the land.
Consist of 55% bituminous rank,
40% subbituminous, and 5% lignite.
AK CBM-1 Well rig
Shallow Gas Exploration
tns
Conclusions from AK-94CBM-1
Multiple seams encountered.
Shallow reservoir targets.
Increasing gas content with increasing depth.
Excellent desorbed gas contents exceeding
245 cf/ton DAF.
Coals are fractured and cleated.
Alaska’s coals could contain as
much 1,000 TCF of gas
