REVIEW OF OIL AND GAS FIELDS
The Buck Creek field is in sec. 17, T. 36 N.,
R. 63 W., Niobrara County, about 2 miles
northeast of the Little Buck Creek field. The
structure is apparently a small dome on the
eastern portion of the Lance Creek-Little Buck
Creek structure. The Pierre shale forms the
surface at an elevation of 4,269 feet.
In October 1919 the first well drilled in the
area, in the SE1/4 sec. 19, was completed as a
dry hole. The discovery well, in the NW1
SE1/4SW1/4 sec. 17, was completed in October
1952 for an initial daily production by pump-
ing of 90 barrels of oil from the Dakota for-
mation which had been jet-perforated from
4,318 to 4,324 feet. Three other wells drilled
in the area were completed as failures. The
log of the discovery well shows the following
depth, in feet, to the top of formations: Nio-
brara, 2,687; Carlile, 2,875; Greenhorn, 3,280;
Mowry, 3,796; Muddy (Newcastle), 4,044;
and Dakota, 4,236. Analysis of oil from the
Dakota is given on page 345.
Cumulative production to the end of 1956
amounted to 8,871 barrels of oil. In July 1956
the one well in the field was abandoned.
The Bunker Hill gasfield (fig. 30) in secs.
29 and 32, T. 27 N., R. 89 W., Carbon County,
occupies a symmetrical elongated dome with a
structural closure of 750 feet. The Bunker
Hill dome is 21/2 miles northeast of the Wertz
field and 2,800 feet lower structurally. The
structure is defined clearly, as it is surrounded
almost completely by outcrops of several
Mesaverde sandstones. The lower resistant
sandstone members of the Mesaverde forma-
t.ion outcrop on the crest of the dome at an
elevation of about 7,000 feet.
In 1932 a dry hole in the SE1/4SW1/4 sec.
29 was drilled to the First Sundance sand at
6,748 to 6,791 feet. In 1.937 a well in the
SE1/4SW1/4 sec. 29 was drilled only 100 feet
from the hole drilled in 1932 and was com-
pleted to produce initially 5 million cubic feet
of gas daily from the Shannon sand at 1,224
to 1,480 feet. Subsequently, additional wells
were drilled, and the dry hole drilled in 1932
was recompleted as a gas well in the Shannon
sand. A combined open flow of about 8 mil-
lion cubic feet of gas a day was developed;
the shut-in wellhead pressures averaged 500
In 1943 a deep test was drilled in the NW/
NER4 sec. 32 to the Madison lime at 9,392 feet,
and no gas or oil was found. The depth, in
feet, to the top of formations logged in this
deep well is as follows: Frontier, 5,052;
Dakota, 6,345; Tensleep, 8,785; Amsden,
9,151; and Madison, 9,282.
In January 1950 the four Shannon-sand
wells were producing about 750,000 cubic feet
of gas a day. Analyses of the gas from the
Shannon sand and water from the Dakota for-
mation are given in tables 8 and 9 (pp. 287
and 293, respectively). The production for
1953 was 54 million cubic feet of gas, and the
cumulative total to the end of 1953 was 3,432
million cubic feet. No production has been
reported for the field since 1953. Seven gas
wells had been drilled in the field as of Decem-
ber 31, 1952; all were abandoned in 1953.
The gas flowed through 111/2 miles of 8-inch
line to Mahoney dome, where it formerly
entered the Mahoney-Rawlins gasline. The
proved productive area of the Shannon reser-
voir was approximately 550 acres.
The Burke Ranch field (fig. 31) is in secs.
7, 8, 17, and 18, T. 37 N., R. 78 W., and sec.
12, T. 37 N., R. 79 W., Natrona County. It is
61/ miles northwest of Sage Spring Creek
field and about 10 miles southwest of Salt
Creek field. The field produces from a strati-
graphic trap in the Dakota sandstone. The
Mesaverde formation is exposed in the area at
elevations ranging from 5,450 to 5,600 feet.
The discovery well in the NW1/NW/
NW1/' sec. 18 was completed in August 1953.
Initial daily production was 100 barrels of oil
from the Dakota sandstone at 6,658 to 6,672
feet. The well had been drilled into the Ten-
sleep formation, which contained water. To
the end of 1957, 16 oil wells had been drilled
in the field. The initial daily production of
these wells ranged from 20 to 1,680 barrels of
oil. The log of the discovery well shows the
depth, in feet, to the top of formations as
follows: Teapot, 915; Parkman, 1,280; Steele,
1,885; Shannon, 3,140; Niobrara, 4,547; First
Wall Creek, 5,380; Second Wall Creek, 5,779;
Third Wall Creek, 5,944; Mowry-Thermopo-
lis, 6,282; Dakota, 6,653; Fuson, 6,670; La-
kota, 6,730; Morrison, 6,744; Sundance,
6,920; Alcova, 7,353; Chugwater, 7,380; Em-
bar, 7,943; and Tensleep, 8,286. Analysis of
oil from the Dakota is given on page 345.
Average daily production at the field in
January 1958 was 991 barrels of oil. The
production during 1956 was 269,531 barrels.
Cumulative production to the end of 1956 was
657,013 barrels of oil.
Oil from the field enters the pipeline from
the Salt Creek field to Casper, Wyo.
