New Map Covers Cut Bank
Timely U. §. G. S. Publication ÉÉH
Covers Area Now In Limelight
Covering an area in which there is mounting interest, the U. S.
geological survey has ready for public distribution a new map of
the Cut Bank oil and gas field and the western portion of the Kevin
Sunburst field.
The new map is a thorough revision of the preliminary structure
contour map of the Cut Bank region by C. E. Erdmann and N. A.
Davis, which was released by the survey in May. 1939, and contrib
uted to the exploration and development of the south Cut Bank
district, Blacktail area. Twin [Rivers nose (Reagan pool), Blackfeet
nose, Hay Lake nose, and other areas.
vision was started in September,
1943, by C. E. Erdmann and was
continued during the fall and win
ter of 1945 and 1946 by William
Beer and J. W. Nordquist. -
The revision embraces all ele
ments of the older map, which cov
ered Twps, 30N to 37N, inclusive,
s. 3W to 8W, inclusive, an
1,728 square miles.
The practice of showing structure
contours on the top of the Colorado
shale at 100-foot intervals has been
continued, but the accuracy of the
contours has been improved and an
interpretation of faulting has been
added. Other significant changes
and additions include stratigraphy
of the lower Kootenai productive
sands, areal geology, culture (roads,
airport, etcd, field development
(approximately 1,100 new well loca
tions, oil and gas pipelines, refinery
ownership) and figures of oil and
? as production for the Cut Bank
ield. The map now shows by stan
dard symbol the productive status
on April 1, 1946, of more than 1,950
wells drilled for oil and gas. A strat
igraphic cross section across the
Chalk Butte nose and the north Cut
Bank and west Kevin districts is
included, as in the earlier edition
may be purchased from
the director, geological survey,
Washington 25, D. C., at 25 cents
a copy and is also available for over
the-counter sale at the geological
survey offices at 314 Boston build

mercial club, Billings, Mont.
The surface of the region is oc
cupied by widespread deposits of
glacial drift and alluvium that are
not shown on the map. All exposed
rocks are of Upper Cretaceous age.
Recognized formations are, in down
ward sequence, the Horsethief sand
stone, Bearpaw shale. Two Medicine
formation, Virgelle sandstone and
Transition Zone (Telegraph Creek
equivalent) that constitute the Mon
tana group, and the upper one-third
of the Colorado shale. Concealed
rocks consist of the remainder of
the Colorado shale, including the
Blackleaf sandy member, the Koo

Casper, Wyb., and Cohi
ceous age, the Ellis group of Jur
assic age, the Madison limestone of
Lower and Middle Misslssippian
age, and the Three Forks shale and
Jefferson dolomite of Devonian age.
Pre-Devonian Paleozoic sediments
are doubtless present but have not
been drilled into in the map area.
This general sequence, with signif
icant variations in thickness and
character. Is shown in a columnar
section on the map.
The geologic structure or the re
gion is dominantly homoclinal with
an inclination of about 100 feet per
mile west from the cffest of the
Sweetgrass arch, which is a few
miles east of the map. This condi
tion is diversified by a series of
terraces and anticlinal noses that
plunge north-northwest, some of
which include areas of small local
closure. Several small epi-anticllnal
faults have been developed by con
touring in Cut Bank oil field. Sub
surface evidence for their existence
is suggestive, but it is not conclu
sive, and they are not expressed at
the surface. There is -some additi
onal structural and iso-oil gravity
contour evidence that similar faults
may cut the sands that yield the
oil and gas. If this is so, operators
might bear in mind that such faults
may serve to divide the field into
units that may have a significant
effect on both production and sec
ondary recovery programs.
Production in the map area is
chiefly from the Cut Bank oil and
? ;as field, and from various oil pools
n the west Kevin district. Smaller
producing areas are the nearly ex
nausted Border - Red Coulee field
and the Darling, High Gravity, Rea
gan and Thorpe pools.

According to incomplete re

Bill Hanlon has completed the
eighth and ninth in an un

wells drilled by him to the deep
sands on the field's East dome.

topped at 1680, then got oil in the
top of the Ellis at 1788. Pipe was

in 12 hours and the well is now on

With a rotary table elevation of

Union Launches Lime Test
In Main Cut Bank Gas Area
Another interesting and important attempt to open up additional
Madison lime production, near the central part of what has been
hitherto developed
being launched by the Union Oil Company of California.
The company has made location for a lime test on the A. E.
Teterud farm, in C SE NE 34-36N-5W, on a 320-acre tract on which
as the main gas area of the Cut Bank field, is
by gas production.

It is approximately 1% miles

1926 by the Sandpoint interests.
Tying it in with more recent his

in a break in the Madison lime,
below a 9,000,000.000-foot gas flow

plugged off, to save the gas, and
a twin well is now being drilled
to the oil zone.

by Union-Tèterud No. 2 would logi

Montana HAS A Conservation Law
Cobb Calls Krug's Attention
To Error In Chicago Speech
Interior Secretary Krug was quite definitely off the beam when
in a recent Chicago speech he listed Montana as among states need
ing oil and gas conservation laws.
Strongly calling attention to this fact is the following letter sent
Krug this week by A. B. Cobb, chairman of the Montana Oil Con
servation board. Says Cobb's letter, in full:

My attention has been directed
to ah article published in the Nov

newspaper issued ffom Ix>s Angeles,
California, which is widely circu
lated and read, I umlerstand, by
people interested in the petroleum
industries of the western stales,
wherein you were quoted as having
made the statements in your speech
delivered at the çonvention of the
Amercan Petroleum Institute, re
cently held in Chicago, (read by
R. K. Davies in your absence),
which I quote as follows, viz:
"Far Western states were
bluntly warned by Secretary of
the Interior J. A. Krug in his
API convention address (read
by R. K. Davies in his absence)
that state oil conservation legis
lation is necessary to insure an
adequate supply of petroleum
in the area best suited to serve
the needs of the Pacific'.
"The Secretary mentioned
specifically California, as well
as Montana, Wyoming, Colorado
and Utah as states which do not
have such laws."
Assuming that you were correctly
quoted, I respectfully note an ex
ception to your statement insofar
as you Included Montana as one of
the states having no oil conserva
tion law. That was a mis-statement
of fact and so unfair to the progrès
slvely minded leaders in the oil
