REVIEW OF OIL AND GAS FIELDS
3.7 million cubic feet of gas; Lakota, 0.5 mil-
lion cubic feet of gas; Morrison, 205,000 cubic
feet of gas; Phosphoria, 1.0.7 million cubic feet
of gas, 408 barrels of oil and no water; and
Tensleep, 6,500 barrels of oil and 2,584 barrels
Oil and gas production during- 1956 was
2,534,498 barrels and 5.35 billion cubic feet,
respectively. Cumulative oil and gas produc-
tion to the end of 1956 was 23,663,133 barrels
and 140.5 billion cubic feet (these figures in-
clude South Sand Draw gas).
From 1922 to 1928, 5 to 6 million cubic feet
of gas a day was piped to Riverton, Wyo.,
where it was processed in an absorption gaso-
line plant and the residue burned in a carbon-
black plant. The manufacture of carbon black
was discontinued in 1928, and the gasoline
plant was moved to the field. A 12-inch,
welded-joint pipeline was laid from the field,
a distance of 75 miles, to connect with the
Wertz-Mahoney-Casper pipeline at Poison
Spider field. In the fall of 1937 the Wertz-
Mahoney-Casper gasline was shut in, and a
second 12-inch pipeline was laid from Big
Sand Draw via Muskrat field to Casper. A
6-inch gas pipeline was laid from Big Sand
Draw to Rawlins, Wyo., in 1951. Oil from the
field moves through an 8-inch line to the
Crooks Gap field and from there to a refinery
at Sinclair, Wyo.
The South Sand Draw oilfield (fig. 22) is
in sec. 26, T. 32 N., R. 95 W., Fremont County,
2 miles southeast of the Big Sand Draw gas-
field. The structure is a small, faulted anti-
cline on the southeast-plunging nose of the Big
Sand Draw anticline. White massive sand-
stone and white marl of Miocene age form the
surface at an elevation of 7,160 feet.
The discovery well, in the SE1/4NW1/4SE1/4
sec. 36, was completed October 13, 1953. Ini-
tial production by pumping was 285 barrels of
22 API gravity oil from the Tensleep sand
at 8,600 to 8,614 feet. In December 1953 the
well was recompleted in the Phosphoria lime
at 8,184 to 8,214 feet. Initial flowing produc-
tion was 254 barrels of 330 API gravity oil
a day, following acidizing with a total of 3,000
gallons. The log of well No. 2 in the C SE1/4-
SW1/4 sec. 36 shows the depth, in feet, to the top
of formations as follows: Frontier, 4,520; First
Frontier, 4,648; Second Frontier, 4,795; Third
Frontier, 5,063; Fourth Frontier, not present;
Fifth Frontier, 5,330; Muddy, 6,154; Dakota,
6,317; Dakota sand, 6,360; Lakota, 6,446; Mor-
rison, 6,490; Sundance, 6,737; Nugget, 7,032;
Chugwater, 7,250; Alcova, 7,703; Dinwoody,
8,563; Phosphoria, 8,721; and Tensleep, 9,140.
Analyses of oil from the Tensleep and gas
from the Muddy and Phosphoria formations
510267 0o-60 4
are given on page 339 and in table 8 (p. 287),
respectively. Four wells have been completed
as oil wells in the Phosphoria lime, and one
was a failure.
Production for 1956 was 93,251 barrels of
oil. The cumulative production to 1957 was
320,254 barrels. The field is connected to the
oil pipeline from Big Sand Draw field to Sin-
Unit plans for developing and operating
Big Sand Draw and South Sand Draw fields
were approved by the Secretary of the Interior
R. 95 W.

The Billy Creek gasfield (fig. 23) is in the
west half of T. 48 N., R. 82 W., Johnson
County. The structure is an anticline with a
closure of about 500 feet and an axis that
forms a reverse curve. The east flanks of the
structure dip 7 to 150 and the west flanks
100 to 150. The Cody shale outcrops at eleva-
tions of 4,930 to 5,110 feet.
The field was discovered in January 1923
upon completion of a well in the SE1/ SE1/4
