in order that cross sections through
the field might be drawn up 10 cor
relate the different pay sands.
When the bureau OF mines first
started work in the Hewitt field it
was the current opinion phat the pay
sands were lenticular throughout,
ranging from 1900 to 220O feet in
depth, or that the formation lay in
series of minor structures. The
first work done by the bureau was
the correlation OF the so-called Hewitt
pay sand and to prove the steep dip
Of the oil sand. BY correlation, the
pay sands were found to be continu-
Gus and dipped very steeply, the Hew-
lit sand in some places dipping as
much as 1900 feet 10 the mile.
The correlation of these different
cross sections enabled the engineers
to conclude that there were also deep
III pay sands in the Hewitt field. Rec
concentrations were made to certain
operators to drill deeper In order Va
acquire q production from these deeper
sands These recommendations were
carried out by a number OF the oper-
ator8 with the result that a deeper
sand was encountered which in some
eases was miore productive than the
Hewitt sand.
Samples Of water from the water
bearing strata were collected through
out the field and were sent to the
bureau OF mines station at Bartles-
vile for analysis. This was done in
order to help ont the operator in case
he should at q later date encounter
water troubles. If an operator en-
counters water trouble at later da1s
n sample can be taken and analyZsd
The result Of this analysis can t6en
be compared with the analysis q TIE
water samples taken while the vel
or any adjacent wells were being drill
ed. This allows the bureau TO compute
tunity to make recommendations for
overcoming this trouble. Samples Of
casinghead gas were taken throughout
the field In order that they might be
analyzed and tho gasoline content
|
determined.
At the end of July the engineers
werc ordered back to the Bartlesville
station due to the fact that funds for
the investigation Of this field were eX-
| hmusted. Through the efforts Of GER
tain operators who appreciated the
work OF the bureau, Mr.. ReeS Ev-
ans and Mr.. James Barron, secretary
OF the Ardmore Chamber of Commerce
an agreement was reached with the
bureau or mines to allow the men tc
spend an additional three months in
the field ON funds furnished by the
operators. All operators generously
contributed to this fund.
A few special Investigations and re
ports were made on individual prop
critics. The limited time made it neces
sary to stop before all properties were
covered. Reports were submitted I,
the operators covering the following
subjects: suggestions for increasin,
production, such as deepening, diff
ferent methods of pumping, ETC.; rec
concentrations for conserving natura
{ gas; recommendations for reducin,
; idle time Of pumping wells; sugges
tions for more efficient distribution
| OF duties Of field men; minimizing
operating expense; recommendation
for gaging wells individually; hiscov
F. cry OF certain wells that passed tn
top Hewitt sands with rotary tools
suggestions for testing and method o
repairing wells making water; sugges
: tions for conducting drilling campaign
on edge properties with view o
locating the limits of the field witt
minimum number OF dry holes; rec
concentrations to operators for prope

decline curve of the field and certai
other decline curves for individua

/, tmap showing relative production Q
various areas OF the field; estimation
of petroleum reserves on certain prop
critics and the probable yields per acr
foot for certain properties; the dis

cased unsystematically as regards IN
. upper water and Hewitt sand. Throug
a one of these reports the production L
