per acre for 5,457 acres and $90.67 per acre for 4,782 acres of Federal coal
land in Wyoming; previous bids averaged about $40 per acre. The acreage was
to be included under Humble's liquid fuel research program. The company contracted
for 50)000 acre-feet of water annually from the Yellowtail Reservoir for
its proposed plant to convert coal to liquid fuels and other products. 
 PP&L revised the planned construction of the new fourth generating unit
at the Dave Johnston generating plant. New plans are for a $44 million, 330-megawatt
addition to be in service by mid-1972. West of Green River the company began
constructing a $4 million facility which will supply both process steam and
electric power to Allied Chemical Corp. The first of its kind to be built
and operated by PP&L, the installation will use steam for power generation
before delivery of the steam to Allied. 
 
 Natural Gas.—Marketed natural gas declined 3.3 billion cubic feet
in quantity and $239,000 in value. At yearend, the State Oil and Gas Conservation
Commission reported 749 active, producing gas wells, 8 more than at the end
of 1966. The leading gas-producing counties were Sublette, Sweetwater and
Fremont. 
 Beaver Creek, Fremont County; Greater LaBarge (including Le!Barge and East
and North LaBarge), Sublette County; and Worland, Washakie County, were again
the principal producing gasfields with outputs of 16.8, 16.2, and 15.0 billion
cubic feet, respectively. 
 Estimates of yearend reserves by the American Petroleum Institute (API)
and the American Gas Association, Inc., (AGA) placed the State gas reserves
at 3.7 trillion cubic feet, a 2.5-percent increase over that of the previous
year. Additions from new fields and new pools were 9.7 billion cubic feet;
extension and revisions added 349.4 billion cubic feet. 
 On the basis of initial production the most important of the eight gas discoveries
was the Shamrock Oil & Gas Corp. No. 1 UPRR Quealy well, Sweetwater County.
The completed well, in sec 25, T 20 N, R 95 W, flowed 11.5 million cubic
feet of gas and 130 barrels of distillate per day from the Almond formation
(C retaceous) at 9,450 to 9,468 feet. The new field, south 
of the Wamsutter gasfield, is near the pipeline of Colorado Interstate Gas
Co. 
 One of the most significant exploratory wells in the State was the Mountain
Fuel Supply Co. and Union Pacific Railroad Co. No. 19 Unit, Church Buttes
field sec 8, T 16 N, R 112 W, Uinta County. Completed at yearend, the well
was the second deepest drilled in Wyoming and the deepest producing well
in the State. It was drilled to a total depth of 19,526 feet; casing was
set at 18,754 feet; and the well plugged back to 18,666. Completion was from
perforations at 18,050 to 18,200 feet in the Morgan formation (Pennsylvanian)
for an initial daily potential of 6.4 million cubic feet of gas and 310 barrels
of 48° API condensate. Earlier, the well was tested at a rate of 10.5
million cubic feet of nonflammable gas from the interval 18,313 to 18,431
feet. Established production at the field was from the Dakota formation (Cretaceous).

 Carbon County had four gas discoveries 
—a new field, two new pays, and a new pool. Near the Colorado border
Wolf Exploration Co. discovered the Smith Ranch field with its No. 1 Balta
well which flowed 2.6 million cubic feet of gas per day from the Wasatch
formation (Tertiary). The new pays were in the Diamond Ranch and Simpson
Ridge fields; the new pool was in the Cow Creek field. Several indicated
gas discoveries were incomplete at yearend. 
 Natural Gas Liquids.—Total natural gas liqtsids increased 4 percent
in quantity and value. Yield of natural gasoline was 2.8 million gallons
above that of 1966; output of LP gases was 7.7 million gallons higher. The
increases resulted from plant construction and expansion completed the previous
year. The 27 plants had a combined daily capacity of 2 billion cubic feet
of gas. AGA and API estimates of natural gas liquids reserves at yearend
were 87.2 million barrels, an increase of 876,000 barrels. 
 True Oil Co., Casper, began operating its 8.5 million-cubic-foot-per-day
plant at Coyote Creek, Crook County. The Glenrock plant of Cabot Corp. was
dismantled and moved to Texas. The plant of Amax Petroleum Corp. at Boone
Dome was
