ResoIute interests, was drilled by
General Petroleum Corporation un-
der an operating agreement with
ReSolute. At GAS feet, the well was
completed for a daily production of
az least 125 barrels of 4Sgravity oil
daily, from the second Frontier
sand. Biologists. most of whom
were more than a bit skeptical con-
corning the possibility of production
in this field, are inclined to classify
the field as having once been a
part of the Elk Basin uplift, now
separated from Elk Basin by fault
with a throw of more than 1000
feet.
With these facts as a background,
early 1945 developments are again
calling attention to this area at the
north end of the famed basin.
First. Continental on Com
pany is getting strong tndica-
tons of production In wildcat
approximately three miles south
OF the nearest production In
Elk Basin. The c0mpany's No.
Ida Go0dstein, NE SIC SW 70
SIN 9SW, got a f0,000, O00-f0ot
gas flow ON a fOur.minute drill
stem test I'm the top of the
Dakota sand, at $500. Previous
IL, IL had yielded a flow of
5000, 900 cubic feet In the second
Frontier, topped at ASA feet.
Likelihood that this well viii
find production I'm the Embar-
Tenslecp zones Is now c0nsid-
cred bright, possibility that IL
fulfilled win lead TO a sharp
upward revision of Elk Basins
production outlook.
Next, General Petroleum has
announced that IL intends TO
test the Tensleep I'm a well now
drilling In the Badger Basin
field, on an operating agree
ment with ResoIute, about three
quarters of a mile from the
nearest Resolute producer. This
well, now making hole past
1000 feet with rotary tools, is
expected TO set a new Rocky
mountain depth record If sue
cessfuIIy carried TO the objec-
tive, likely TO be reached at
about 1900 feet.
Operators now are awaiting ar
other logical move in the area
further testing by General Pet o.
the Clark's Fork structure. The dis
covery well is now shut In, wit
rotary moved off, awaiting arrive
of production equipment. II is e.
pected to be fully three months bt
fore drilling mud and water
cleared from the Frontier sand
the discovery well and its real POI
sibilitieS ascertained.
More than usual interest also a
taches to the deep test on Badge
Basin For Badger Basin is ava
from the rim of the Big Horn bash
and unlike the sharp-dip structure
around the edge 1t is felt result
found by the deep test may hay
an important bearing on future d
velopment further south in tn
basin, near it's center, away frol
the exposed and sharply dippin
structures around the rim.
For, the center of the basin, wit
geological indications obscured
thick overburden, is yet u
drilled. At its widest part, about
miles separates structures on Il
eastern and western rims.
In between is a geological n
mans land, with operators Deepen
ent upon geophysics in their hui
for structural indications, ar
hesitant to be the first to ventu,
in drilling the excessively dee
holes believed necessary to reaC
possible production.
If General Pet finds oil in Il
Tensleep in Badger Basin, ope
ators may cast aside their doub
and take the plunge into the cent
Of the Big Horn basin.
All and all, an interesting We
seems in prospect on the Montar
Wyoming border.
