far productive on Mosby Dome
and East Dome, though drilling
showed this well TO be high on
structure, appears TO demon
strate that faalfing In this field
may be deeper seated than was
believed by some, and that
down to S,500 feet at least the
accumulation of oil win be de-
termined By fault lines, more
than any other feature. This Is
I'm direct confederation of the
belief of H. III. Schwartz, Jr.,
who located the SchrOck-Fifer
discovery well and subsequent
producers ON the same 100 acres
as that on which Standard of
California had drilled q $500
foot dry hole.
Some are now inclined to think
this condition may lead to some
interesting results, with production
likely to be found in locations well
off the main axis, providing wells
are located down-structure from
dominant faults, but on the upthroW
side of the fault blocks. This theory
is likely to be tested very shortly.
In the Mosby Dome section OF the
field, Farmers Union Central Elk
change is at the testing stage in its
first drilling venture in this field,
its No. State, on acreage for which
the Exchange bid $4,000 at state
lease sale several months ago. The
No. has drilled to the pay horizon
and is testing.
A location to the east, second
well being drilled by the Exchange
on its state acreage, has made hole
past 900 feet and is due to COM
plete within a few days.
A few locations to the west, Con-
tinental Oil company has drilled in
its No. II Brown and is running
Schlumberger at / $685. 1t is reported
to be showing only small amount
of oil.
Several miles to the west, on the
fields West Dome, both Ralph
Chamberlain and B. R. Gamer are
testing oil showings in the first
Morrison sand. Both are still having
water trouble. Neither has made any
move to drill deeper for a test of
the second Morrison. Idaho interests
are reported planning another well
in this same area, on the western
edge of this dome, on portion of
the F'radd lease, but no formal loca-
ton has been made.
