Issues Data on The
Robertson District

Robertson District
The Oklahoma state geological sur
vey has issued Il new map on the
Robertson field of Garvin county, and
adjacent areas. dated March 3. 1929.
The map is complete in number of
details. giving a characteristic log of
the field, commercial analysis of the
oils. and on the reverse side of the
map explains in detail the location, "
drainage and topography strait
graphy," character and depth of
sands" "Arkose members" surface
structure" ''sub-surface structure"
production" drilling operations" "
failure of the field" and present pro-
ductive area"
Adjacent Structures.
In addition TO the proven area, the
map shows q structure to be in the
south half Of section and 3, 1n.3w,
and the north half of sections 10 and
II, ln-3w, which lies Immediately
north of the proven area. Another
very interesting anticline covers the
east half OF section &c. 2s-3w, and
section ! and L., ln-3w. Ii this
anticline lies according to the geologi.
cal data rs mapped, there is reason
to believe that the deepening of the
Davis-Youngcr well on the Harrell farm
in the southwest of the southwest
quarter of thes northeast quarter ot
ot.. -. lay
taken by the Wrightsman Oil Com
pany, will give new life to that por-
tion of the field, as it has for some
time been considered as condemned
territory. The avis-Younger well
had been drilled to 1860 feet. and fail.
cd to encounter any sands.
Another anticline shown on this
survey is known as the Tidal Usage
structure, and covers all of section
"a, 2n.3w, with small portions of sur.
rounding sections. The Tidal Usage
people are now drilling q test on this
structure on the John farm in the
northeast corner of the northwest
quarter of the southwest quarter of
section "a, 2n-Sw.
The log used on the map TO indicate
character of formations encountered
in the Robertson field is that of the
Wrightsman-Pernell No. ! on the south.
west corner of the southwest quarter
of the southwest quarter of section
8, ln-3w, which found the pay at 1882
feet and started with initial produc.
tion of l3O barrels and 1000, 900 feet
of gas
Gravity OF Oil.
In the commercial analysis of the
OIL the gravity degrees Baume &c
degrees FL IS given as ranging from
23-9 degrees Be, to 2S.5 degrees Be
First Well Drilled.
In the review of the field it Is
stated that the first we'll was drilling
in June 1920, in the northwest cor
ner of the southwest quarter of the
northwest quarter of section 15, In
3w, by the Magnolia Petroleum Com
pany on the Cowan farm, and came ir
as gasser with production of about
$4,000, 900 feet. The deepest hole IL
the field was drilled to total deptf
of 42s7 feet by the Magnolia Petro
leum Company in the southeast corner
OF the northwest quarter OF section 3
ln-3w. The first well to be drilled
in the eastern part of the field wa
put down by the Magnolia Petroleum
Company on the Hart.Newberry farm
In the northwest corner Of section IA
ln-3w, and came in with initial pro
duction Of 200 barrels.
Drainage.
Under the heading drainage ant
topography" the Robertson field /
described as lying in the drainage basi
of Salt Creek, a perennial stream
which is branch of the Wild Hors
Creek belonging to the Washita rive
system. The relief of the field is no
over $50 feet. The range In elevation
above sea level is from about S15 fee
TO 1925 feet. The region has a rollin
topography and is covered with pos
oaks and black jack timber.
Relative TO the straitgraphy of tn
field, attention is called To the fac
that in some OF the sandstone bed
q quartZite Is found and in the sout
part of the area an arkose with pin
feldspar occurs. The Importance c
this is pointed out in that in drilln
to the north and west the formatio
may be found some distance beneat
the surface and be mistaken 70

Sands.
First producing sand in the field
found from 'l20 feet to 1880 feet an
is from five to so feet in thickness
The. gas wells vary in volume froi
100000 cubic feet to $4,000 900 cub
feet of dry gas. Below the first "a
a sand is found at from 1,240 fec
TO 1860 feet ranging in thickness fror
five to 80 feet. Below this sand 0
about 1i00 feet an important oil an
gas producing horizon is found wit
production ranging from % to 70
barrels daily and gas yields as high O
20,00Q,o 900 cubic feet are found wit
the oil. There Is good evidence. state
the report. that this sand is col
unuous over the entire field. New o
sands have been uncovered since ii
date OF the report at depths rangin
around 1900 feet which are producin
