tNaNiNN Ah' 'Hi'nNoht hae A'i'
as one OF the most important areas
IN the state. Ira Rinehart. special
oil writer for the Daily oklahoman,
has the following TO say In a review
Of the field and a summing up OF
It's possibilities
"Will The chickasha gas district
be found productive OF oil when the
sands below the shallow gas sand
are explored?
This IS one OF the most impor.
tant questions to be solved In Okla
h0ma at this time. To date. all Of
the wells. favorably located on
structure. have stopped drilling when
the big gas has been found. and such
small number OF deep wells have
been drilled In that section OF the
country that II IS difficult 10 fore
cast what the outcome of explora.
tion Of the lower sands will be. II
appears probable, however, that oil
will be found al some point on the
structure and oil men are watching
the outcome closely.
Well Logs Are Watched.
"The first procedure OF practical
oil men in trying to satisfy them
selves that lower sands offer posi-
bilities Is to correlate log records
OF wells drilled near the field and
Of the producing wells drilled in
the Cement field to the westward.
"There has been considerable list
lessness on the part of drillers in
keeping log records. however, and
geoogists have found It exceedingly
hard to satisfy themselves on cor
ION work, For instance, II Is
theory that the 1,300-foot gas at
Chickasha Is the same as the 1900
foot sand found az Cement. but no
log records have been found to com
pletely confirm that theory.
Possibilities Are Good.
"a fact which makes Chiekasha
deeper sand possibilities look so
good Is the fact that producing
sand has been found at such
shallow depth. AS far as can be
determined the gas sand is found
near sea level, and at about 100
feet in the Pennsylvania series.
"If good producing sand is
picked Up at only 100 feet in the
Pennsylvania, there must be good
possibilities for a much greater
depth in that series. The basis
for figuring the gas sand to lie in
the Pennsylvania is that in the
Chickasha-Duncan district the geolo-
gists identify the Pennsylvania as
being a brown rock, and about 100
feet of it is found above the sand.
"The shallowness of the gas sand
makes one compare the Chickasha
situation more or less with Ton
kawa In the latter field many
shallow gas sands, notably one from
500 to 900 feet are found above the
oil sands at 1890, 2,100 and $500
feet. The gas sands parallel the
oil sands in remarkable manner, al
though all are exclusively gas sands
and have never been found to con-
tain oil 1t Is admitted that Chick
asha's gas is not being found in
the same age formation as Tonka-
was. but that would not have to be
necessary.
Folds Are Pronounced.
"Chickasha's folding is pronounced.
With the meager amount of drilling
thus far done, a 200-foot southwest
dip has been indicated as well as
1OO-foot northeast dip. The east dip
has not been indicated, but as this
is being written, there is an indl-
cation that it is either about to be
discovered as being very pronounced,
or that the sand is subjected to
being wavy.
"The Atlantic Oil Producing COM
pany's well in 25-5n-Sw, the most
northeasterly well in the pool, seems
to have found the sand "a feet
lower than the LeMaster gasser,
which it offsets. 1t may be located
down on the east dip. Biologists
say not. but there is a possibility.
Two Folds Are Seen.
"From the latest geology on the
field. it is figured that there are
two folds. the 5.S gas being on one
and the Sunray we'll in 14-4n-Sw be-
ing on the other. On the saddle be-
tween production may be found, and
il may not. 1t all depends upon
whether or not the gas sand, or the
lower sands, if they exist, carry
water. If they carry water, the
saddle will not produce, and if water
is not found, the saddle is expected to
produce. 1t was said in the field
Mondayethat some water had shown
ND in few wells in the north end.
Surface topography of the region
is attractive. Surface geology is
compiled almost exclusively on a
gvp rock about 1 IL feet in thick
ness which is general over the terri
tory, and an excellent marker. rms
formation is about 200 feet higher
than the formation which is used as
