OIL IS WHERE YOU FIND IT

Waller had showing Of oil, near the top
of the DevOnian; 9S5 feet below the ton Of
the Madison lime and 30 feet below the
top OF the DevOnian is the horizon at which
the Frazer Bears Den test found oil We
have bottle Of this oil-the first DevOnian
OH ever found In Montana. Marked on the
outside Of the bottle is the ways warning:
Handle with care: first Dev0nian oil In
Montana-vaIue, 100000" The figure repre-
sented the cost of the well; 1880 feet below
the top Of the Madison lime and 3z5 feet
below the top Of the DevOnian Is the horizon
at which the Erickson COuIee well lust north
Of the Sweetgrass Hills, had its showing of
oil; 1850 feet below the top Of the Madison
lime and 375 feet below the top of the De-
vOnian is the second oil horizon found at
Bears Den, above which are the rich petrO-
hferOus shaIes found in several wells in
Montana and Alberta; 1O75 feet below the
top Of the Madison lime and $50 feet below
the top Of the DevOnian is the Moose dome,
(AIberta) producing horizon Exposures in
the Rocky mountains indicate that the most
petrOIiferOus rocks in the Devonian are at
the base Of this formation but none of the
wells drilled have reported showings in this
section described by DR.. Charles F. DieSs
of the University of Montana.
800 PLUS FEET:
OrdOvician formation This Is the greatest
producing horizon Of the NTidcontinent. The
principal shOwings Of oil found In the Carter
cOmpanys deep test at Baker were i'm this
formation which had never before been con-
sidered present, let alone possible prOduc-
Ing formation. 1t now develops that the
principal showings of oil found in deep wells
in Kelvin field, such as the POtlatch deep
for4 r. nj
found their oil in the OrdOvician. The
Frazer-R deep test In Kelvin produced
high gravity oil but the terrific pressure
Of the sO-caIled poison gas" which came
IN just above the oil made 1t impossible to
produce that oil, although it was once con-
nected onto the tanks. We have samples Of
he oil from the various OrdOvician horizons
70 be seen by any who visits our office.
Wells drilled in Cascade county have en-
,Ountered this formation and found show
ngs of OIL in locations known to be off
structure A recently completed well drilled
" F. J. Busher and others, west Of Great
Falls, had three good shows of oil In the
lrdOvician-
The OrdovicIan is the "WiIcOx' horizon Of
he Greater Seminole district Moore, Okla
IONA City, BrittOn, Edwards, Crescent,
4OveII, Powell, CARRIER and other Oklahoma
ields, which fields have given some of the
argest wells in the United States Some Of
hese fields which have been prolific pro
ucers In the lower formations had NO oil
IBOvE the Big Lime
If oil is where you find it," the place to
Ind it is BELOW the Big Lime. The only
respect for opening those horizons In
TOntana this year Is the Tarrant- Wood test
n Midway structure, now drilling. BY drill
lg this deep test" to the normal depth Of
,ut Bank wells, Tarrant VIII test the upper
'evOnian-as evidence Of the statement that
Iontana Is the great BONANZA state" Of
he oil industry. Whereas ether states re-
ard only those wells more than 1O,OOO feet
eep as ~deep tests" the areas where oil
known to exist-the place where they
ave already found it--require deep tests Of
St more than 5000 feet.
As Montana has made great fortunes
ON the shallow pools and cheap drilling
BOvE the Big Lime, so viii Montana make
-eater fortunes for those who drill the
laIIOw horizons BELOW the Big Lime.
Our current publication this week deals
It'll developments on Midway structure,
here Tarrant is drilling the Wood deep
ST." to explore the DevOnian. 1t win be
MT to those who request it.
