Also 1t should be brought to the
attention Of the public that these

Of oMntana are the largest producers
of SO to 81 degree Baume crude that
the world has ever known.
Great Credit to State
1t is one more deep cut notch to
the credit Of Montana as an oil state
that nature 80 kindly bestowed upon
her.
The Cat creek anticline, otherwise
known as the Mosby structure, has
two prominent high domal develop
ments, the West Dome and the River
Dome. separated by q deep sypcline.
The River Dome gave up the first
oil in q well drilled by the Frantx
corporation, February, 1920. This
we'll demonstrated that there were
two oil sands within less than 100
feet Of the surface. The first sand
wa not commercially productive in
this dome, but the second sand fur
nished small oil we'll.
The second we'll was drilled by the
Frantz corporation In the West Dome
field. located four miles west Of the
discovery well. While this we'll was
wildcat in a way, production was
looked for in the second sand and at
the same horizon as in the discovery
we'll on the Musselshell river. Here
the first sand gave up a 2,000-barrel
well. It was like a lightning stroke
from clear sky and the news spread
quite as rapidly as thunder clap
would have followed such stroke.
Show Flank of First Pool
Shortly after this development, the
Decker-Collins we'll, located less than
half a mile to the south, drilled into
water In the first sand and estab-
lished the limits down the flank of
the structure of the first sand pool.
The second sand had been productive
In the River Dome. and the Decker
Collins decided at once to continue
to this horizon, but a small oil we'll
with water developed. It was not
commercial and the we'll was drilled
deeper to secure water supply. This
was the first we'll to establish the
fact Of second sand oil pool in the
West Dome, and although It was an
edge we'll and not commercially pro-
ductive, It proved that the second
sand pool was larger, or reached far
Their down the flank Of the structure
than the first sand pool, and that the
good profitable production in the
second sand lay Just above.
In the opinion of the writer, who
watched every development Of the
district, the Decker-C Collins we'll es-
tablished beyond doubt the fact Of q
larger and profitable second sand
pool.
Drilled Many Edge Wells
The next we'll to be drilled to the
second sand in the West Dome field
was the Montacal. It was an edge
we'll and the first results were unsat-
isfactory. The third we'll to be drilled
to this horizon was the Custer Oil &
Gas. well on the north side Of the
structure. It had some oil but not
in . commercial quantity. The Ten
Spot we'll, on the southwest side Of
the structure, was another edge we'll.
too far down the structure to obtain
in the second sand. al
though some oil of q little lower
gravity was developed In the third
Kootenai sand. Water was permitted
to stand on this oil sand full year
and effectually drove the oil away
from the bore hole before 1t was de-
cided to again test the well for pro-
duction. It is needless TO say that
the oil was not there when the opera
ton was resumed.
= The Big Six we'll, located at the
extreme western end of the field.
was drilled to the second sand and
obtained only good showing. This
was the firth well to be drilled into
the second sand. and all of them were
edge wells from the standpoint of
structure, and doubtfully located for
top pool oil, that IL. first or second
sand production.
Drilled Into Water
The sixth we'll to be drilled to the
second sand was on the Unit Petrol
cum holdings on the Miller tract.
This we'll was projected for . deep
teot and the management gave out
that the quantity Of oil In the first
and second sands was not sufficient
to be profitable. There are some
doubts regarding this. particularly -
the quantity Of oil found IN the deep
Or sand. However, Il was cased of
and the we'll drilled . little deeper
into the large water sand to the Koot-
ooai.
BY this. time operators. brokers,
promoters and even biologists talked
much Of Q barren second sand and

f5eld. They had completely forgot
