would pump up to 500 lb. in a shori
time; such a compressor plant has
been designed and built by the Chi
cago Pneumatic Tool Co. We are op-
Grating six Of these machines with
good success. The Ingersoll- Co
and the Rix Compressed Air and Tool
Co. have also designed and built port
able outfits.
In operation, the train is run up to
the well, a pulling mast is set up over
the well, and the rods and tubing are
pulled by means of the winch on the
tractor, or other pulling devices. The
shoe or heavy nipple is then substi-
tuted for the perforated joint of tub
ing, and the stril.g is run in again
with the working barrel.
The rotary swivel and hose, witch
connects it to the ar tank at port
in the top, is attached to the top of
the string of tubing. The Compress
scr is then run lltil the 5al1 is
charged to 400 or y0G lb. pre.p.rr.

out, until the pressure drops 20 $50 or
200 h., when it is too low to be eff
fective.
The tank is then again charged,
which takes from 25 to 35 min, and
the operation is repeated until the
well is cleaned to the bottom; the
well can then be thoroughly washed
out. The pressure is then introduced
into the casing, which forces all the
remaining floating sand and fluid out
through the tubing This operation
leaves the well in a thoroughly clean
ed condition, after which the rods
with working parts of the pump the
run in and again put to pumping.
The tubing shoe is left in the hole so
that the next time the wells are
cleaned out, it will only be necessary
to pull the rods and working parts.
In the Dewey y-Bartlesville district,
the Tidal Co. has cleaned twenty
wells with the air machines, with an
cost of $237.5O per well. The
average time required to clean these
wells was three days, including pull
ing and putting the wells back to
and the production was in
creased an average Of 1 la Dbl. per
well per day, on wells that produced
Id Dbl. per day. The average time
for cleaning with cabletool machines,
in this district, was 81 days per well,
based on the last five wells cleaned
out by this company, and the average
cost is approximately $1,000. The ca
ble-tool cleaning did not noticeably
Increase production.
Cost Is Low
The average cost ($2975O) of clean
ing the wells with compressed air in
cludes fuel, labor and material, de-
probation and royalty.
In January Of this year, we moved
two air tanks to a lease in the south
east quarter of section 1866 bur
bank district) to test the method on
deep wells, the pressure being sup
Piled from stationary compressor
We were not successful on the first
well, because of various new condi-
tions, but, however, as a result of that
experience, the second well was clean
ed out and put to pumping in three
days Exclusive Of the time required
for pulling and putting the wells back
to pumping) with an increased pro-
duction of bbl per day. A third
well was cleaned out and put to pump
ing in five days, with an increased
production of bbl. per day. The
average time in cleaning wells in this
district with cable tools was 26 days.
At Burkburnett, we were confront
ed with a very unusual condition
there was very high back vacuum
with unusually open sand. When US
ing the ordinary method of compress
sed air cleaning, the pressure was
lost in the top sand, where the vacuum
would pull it through. After trying
the methods previously used, a spec
ial tool was devised, with which it
was possible to clean the wells to the
bottom very satisfactorily. 1t is nee
essary to use this method in localities
here there is soft sand foundation
and high vacuum.
