geles, Calf, acquired the we'll and
adjacent acreage on the structure and
carried the drilling down to the pres.
ent depth of 2,612 feet. Oil was en-
eountered in a sandy lime believed to
be the Embar formation at 1855 feet
below which was on oil saturated
sandstone from which the oil flowed
into the tanks at the rate of 100 to
125 barrels daily until the we'll was
put on the pump, since which time il
has been producing from 275 to 325
barrels daily until shut in. This well
was drilled in during the latter part
of August, 1928.
! During the early part of November,
1928, the Midwest Refining company
acquired the property of Rosenberg
and associates on the Frannie struc-
ture and that company IS now drill
ing two other wells as mentioned in
the early part of this paper.
Electric power, developed at the
Shoshoni dam few miles west of
Cody, was used for drilling the dis
covery well, is being used by the Mid
west Refining company in the present
drilling, and probably will be used
exclusively in the further develop
ment of the field, not only in drilling
but also for pumping.
The oil already found in the Fran
ME structure has an asphaltic base.
In reflected light it has dark to
black color, but in transmitted light
its color is reddish brown. The gray
ity of the oil is between % degrees
and 20 degrees Baume and its gas
oline content without cracking is
nearly 23fs. The oil gives off a sui
phurous odor Oregon Basin oil, ac-
eording to an analysis at hand, has
a gravity of 26.6 degrees Baume and
a gasoline content of 21&. With
these figures in mind it is apparent
that the Frannie oil is of slightly
higher grade than Oregon Basin oil.
Prior to the bringing in of the Fran
ME well the Oregon Basin oil was the
best oil of asphaltic base produced in
the Rocky Mountain region. Since
the Frannie oil has a higher gravity
and greater gasoline content than
Oregon Basin, it takes first place at
this time.
The Rosenberg we'll on the Fran
ME structure was brought in during
the latter part of August, 1928, and
tankage was erected Immediately, but
it was not until about the middle Of
September that any oil was shipped
from the field. Up until about the
first of November, when the Midwest
Refining company took over the dis
covery well and adjacent acreage,
and associates produced
and sold approximately $500 barrels
of oil at an average price of $1.14
per barrel at the we'll Most Of this
oil was shipped to the Mapleleaf Re
finery located at Coutts, Alberta, a
distance of 420 miles by railroad
from Frannie. During November,
1928, the Midwest Refining company
shipped and sold 8,270 barrels of oil
from the Frannie discovery we'll at
soc per barrel. During December,
the same company shipped and sold
1921 barrels at soc and during jan
uary, 1929, shipped and sold 1926
barrels at soc per barrel.
The above facts show a very inter-
esting condition and that is that an
producer such as Rosen-
burg and his associates, was able to
sell the oil at 34c a barrel or 4212
more than the Midwest Refining com
pany, subsidiary Of the Standard
Oil company of Indiana, was able to
obtain for the same grade of oil.
Only the upper 81 feet of the EN-
bar formation was penetrated by the
drill in the Rosenberg well. 1t CON
tanned one bed of sandstone about 5
feet thick from 1855 to $3.50 feet in
depth and then the drill began to
penetrate the limestone and continued
in limestone to 2,612 feet, the bottom
Of the hole. So far the log of the
Rosenberg well, as far as it concerns
the Embar formation, corresponds
closely to the logs of the Ohio Oil
company and Utah Southern on the
Garland structure Is miles to the
south. There is no good reason to
believe that the INFESTED beds under
he Frannie structure will be much |
different than those under the Gar
and structure. The fact that the up
