ROTARY SAVES ONE-HALF
WELL DRILLING EXPENSE
Security Hole in COaIinga Is Put
Down for About $4,000.
Others to Follow

The Security at Coalinga, which has
been making rotary test on its prop
erty while the rest of Coalinga looked
on and speculated as to the outcome
has. according to word received from
Coalinga yesterday, made complete
success of the drilling, proving that
wells can be drilled with the rotary in
the Coalinga territory.
The drilling of this well means more
to the field than probably any other
agency and will result in many wells
being put down by this drilling system
Immediately.
The Security has reached a depth of
255O feet and is going to cement off
here. No casing was used to this point,
and only now will the first casing be
put in. 1t will be S1a-inch. The com
pany expects to go into the oil as soon
as the cementlng job is completed.
Three strings of casing were saved in
this well, a total saving in casing alone
of about $4,000. The completed Wei
will have cost the Security company
between $4,000 and $4,000 or about one
half the cost of a we'll drilled in that
territory with a standard rig. The ad-
vantages of the rotary are so obvious
that others in the district have decided
to install it, and on the Coalinga flat
six rotary rigs have been ordered for
immediate delivery.
GOES THROUGH SHELL
The only place where the rotary met
with difficulty in drilling the Security
well was when the hard shell formation
was reached. Work here was very
slow and it took days to make any
headway whatever. But at no time

standard bit.
The Coalinga Crude finished its well
last Saturday at depth of 1885 feet,
and is said to be one of the best in the
section.
The Consolidated at Coalinga is drill
ing and trying to shut off the heavy
flow of water encountered at 1861 feet.
The Coalinga General has finished
we'll No. 5, which is making about 150
barrels day. This company now has
four producers and is drilling two more.
The Pantheon, located on what was
formerly termed 1.-The break" and for
merly known as the keystone, has
reached a depth of 1900 feet. This is
the company organized by Col. Robert
Hayes Smith of San Francisco. Drill
ing at this point is being watched with
a great deal of interest, and the general
belief is the Pantheon will get a good
well.
Another well that is attracting atten-
ton is the Castle, the farthest out
on the fiat, section 4, 20-15. This well is
being drilled with a standard rig and
16-inch stovepipe is being used. This
will probably prove a large area.
KETTLEMEN HILLS ACTIVE
Interest grows in the Kettlemen hills,
The Baird Oil company claims to be in
the oil sand on it's property in the hills,
and the claim is substantated by
Thomas Hayes, one of the best cement
men in the Coalinga field. who says, to
use his own words: "They have nice
sand"
The talk of late that the Standard
was going into the Kettlemen hills
seems to be more or less hot air. 1t is
understood, however. that the Spreckels
outfit, which is the most active in the
Kettlemen hills, has engaged Jim
Pierce, formerly superintendent for the
STANDARD at Coalinga. to take charge
of the Kettlemen hills exploitation.
Four rigs are already up and two are
working.
