ABSTRACT
The Wagon Wheel Water Well No a 1 was drilled to obtain hydraulic data and to provide a water supply for the deep drilling program at the site of Project Wagon Wheel, which is aimed at determining the feasi bility of nuclear stimulation of natural gas reservoirs,,
The well was tested and water samples were collected by swabbing on August 1, 1969, and by pumping on August 26, 1969. In both tests the 760-meter (2,500-foot) section through which the well was drilled was tested through 19 gun-perforated intervals.
The water level in the well prior to the pumping test was 29.9 meters (98.1 feet) below land surface, During the pumping test the water level declined to 47.7 meters (156.6 feet) below land- surface datum while the well was pumped at an average rate of 281 cubic meters per day (51.6 gallons per minute) for 6 hours and 6 minutes, The transmissivity of the aquifer in the vicinity of the well, as com puted from the data of the pumping test, was 26 cubic meters per day per meter (2,100 gallons per day per foot), and the specific capacity was 16 cubic meters per day per meter (O e 88 gallon per minute per foot) of drawdown.
INTRODUCTION
Project Wagon Wheel, a Plowshare Project, is a cooperative effort
of the El Paso Natural Gas Company (EPNG) as operator, the U.S. Atomic
Energy Commission (AEC), and the Lawrence Radiation Laboratory,
The purpose of the project is to determine the commercial
feasibility of nuclear stimulation of natural-gas reservoirs. The
experiment will include: 1} the detonation of a nuclear explosive in
gas sands of Paleocene and Cretaceous age natural-gas formations which
are not commercially productive with present conventional methods of
gas-field development and 2) the evaluation of the effect of the
detonation on the gas-producing capability of the formations.
The Wagon Wheel Water Well No. 1 was drilled to obtain hydraulic
data at the Wagon Wheel site and to provide a water supply for the deep
drilling program at the site. The U.S. Geological Survey performed the
hydraulic tests and related water quality sampling on behalf of the AEC.
This report describes the general geologic and hydrologic features and
hydraulic testing of the water well, and presents the results of the
chemical and radiochemical analyses.
The Wagon Wheel site is located in the Green River basin, NW% sec. 5,
T, 30 N., R 8 108 W., Sublette County, Wyo. (fig. 1).
The author extends his thanks to Messrs. Jack Shaughnessy and
E. S, Oberly, El Paso Natural Gas Company, for their direct and indirect
support during the field work.

GEOLOGIC SETTING
The Project Wagon Wheel site is in the northeastern part of the
Green River basin, a large north-trending structural basin in south
western Wyoming. The basin is drained by the Green River, The Wagon
Wheel site drains westward to the New Fork River, a major tributary of
the Green River,
The rocks underlying the Wagon Wheel site range in age from
Quaternary to Precambrian, The greatest thickness of sedimentary
rocks, about 9,000 meters (about 30,000 feet), in the basin is in the
deep syncline that trends northwestward through T. 30 N,, R. 108 W.,
parallel to the Wind River Mountains (Krueger, 1960).
Continental sediments greater than 4,600 meters (15,000 feet)
thick have been penetrated by drilling in the SE% sec. 5, T. 30 N.,
R. 108 W e (El Paso Natural Gas Company's Pinedale Unit No. 5 well).
For the most part, the sediments of Tertiary and Cretaceous age under
lying the area in and near the Wagon Wheel site have not been designated
as specific formations or members of formations. The complexity of the
geologic environment and a lack of data have prevented the establishment
of definite upper and lower boundaries of formations. In the EPNG Pine-
dale Unit No. 5 well, the stratigraphic section was divided into five
units on the basis of the section found in the Phillips Daniels No. 1
well (sec. 21, T 8 33 N., R. Ill W e , Sublette County, Wyo.) which has
been designated as the Wyoming Geological Association's type subcrop in
the Green River basin. Table 1 presents a general description of the
five stratigraphic units established by EPNG for the No. 5 well.

The sediments penetrated by Wagon Wheel Water Well No. 1 are
described in table 2. The shale associated with the arkosic sandstone
is very readily dissolved by drilling fluids and the cuttings returned
to the surface are often free of shale. The weakness of the sediments
is emphasized by the degree of hole erosion shown on the caliper log
on figure 2. The presence of shale stringers and beds is difficult to
ascertain on the basis of sample cuttings alone. Geophysical logs
(spontaneous potential and resistivity logs, fig. 2) are one of the
better sources of information for the determination of the presence
of shale bodies at a specific depth.

HYDROLOGY
Because of the wide variety of conditions that existed during the
time the sediments in the Green River basin were being deposited, the
hydrologic environment of the Wagon Wheel site is complex. Sediments
of Tertiary and Late Cretaceous age underlying the Wagon Wheel site
contain many sizes of particles deposited under a variety of conditions.
At some places, silt- and clay-size sediments predominate and elsewhere
sand-size particles are most abundant. Individual stratigraphic units
vary markedly in thickness and lateral extent in the basin; overlapping
lenses of sandstone and clays tone are common.
Ground water occurs in the area under both water-table and artesian
conditions. Water-table conditions exist primarily in recharge areas
and in thin alluvium in the stream valleys. Water enters the artesian
system(s) at the outcrops, where precipitation or surface runoff enters
the system directly. Artesian heads vary with depths of aquifers. The
artesian heads decrease with depth in and near the recharge areas, but
increase with depth in and near the discharge areas along the major
stream valleys, because many of the aquifers are poorly connected
hydraulically. Some of the water-bearing units are hydraulically
connected, so that water moves freely from one unit to another.
The water level in the Wagon Wheel water well conforms to the
regional pattern of the water levels in wells near the site (fig. 3).
The direction of initial ground-water movement from the Wagon Wheel
water well is to the west-northwest.

Hydraulic Tests
The drilling of Wagon Wheel Water Well No. 1 was completed July 27,
1969, and casing was then set. Nineteen intervals totaling 52.1 meters
(171 feet) were gun-perforated (fig. 4). The well was tested by swabbing
on August 1, 1969, and by pumping on August 26, 1969.
Swabbing, Test
A total of 32 swab runs were made and about 27.9 cubic meters
(7,380 gallons) of water were extracted from the well during the 7 hours
and 13 minutes of swabbing. The well was swabbed through 5.1-centimeter
(2-inch) ID tubing that extended to 731.5 meters (2,400 feet). The water
level was measured with an electrical deep-well measuring device before,
during, and after swabbing of the well. Measurement of the water level
in the well was made in the annular space between the tubing and the
19.4-centimeter (7-f-inch) casing. The water level before swabbing was
29.1 meters (95.5 feet) below land surface. One hour and 25 minutes after
swabbing was stopped, the water level was 31.0 meters (101.7 feet) below
land surface.
The specific capacity of the well, based on swabbing at an average
discharge of 92.6 cubic meters per day (17.0 gallons per minute), was
4.1 cubic meters per day per meter (0.23 gallon per minute per foot) of
drawdown. The transmissivity of the aquifer in the vicinity of the well,
as computed from the recovery curve, was 26 cubic meters per day per meter
(2,100 gallons per day per foot) (fig. 5).

Pumping Test
The well was pumped with a submersible pump set at a depth of
313.9 meters (1,030 feet). Pumping continued for 6 hours and 6 minutes
and produced 71 0 4 cubic meters (18,875 gallons) (water-meter measurement)
of water. The water level was measured with an electric-contact tape
C"M-scope") before, during, and after pumping of the well. Measurement
of the water level in the well was made in the annular space between
the pump column and the 19.4-centimeter (7-f-inch) casing. The water
level prior to pumping was 29.9 meters (98.1 feet) below land surface.
Two hours and 40 minutes after pumping was stopped, the water level was
30.8 meters (101.0 feet) below land surface.
The specific capacity of the well, based on the 6 hour and 6 minute
pumping test at an average discharge of 281 cubic meters per day
(51.6 gallons per minute), was 16 cubic meters per day per meter
(0 0 88 gallon per minute per foot) of drawdown. The drawdown was
17.8 meters (58.4 feet) during the test. The transmissivity of the
aquifer in the vicinity of the well, as computed from the drawdown
and recovery curves, was 26 cubic meters per day per meter
(2,100 gallons per day per foot) (figs. 6 and 7).

CHEMICAL ANALYSES OF WATER SAMPLES
Two water samples were collected from the well during the swabbing
and pumping tests. Table 3 shows the results of the laboratory analyses
of the samples. The water from the swabbing test contains much more
barium, boron, copper, lead, iron, and sulfate, and less sodium and
chloride than the water from the pumping test. The numerical differences
between the constituents may be attributed to the fact that the sample
from the swabbing test was obtained only a few days after the well was
completed. The swab water sample was probably still contaminated by
drilling mud and the cement placed behind the casing. The pumped sample
was obtained after at least 132 cubic meters (35,000 gallons) of water
had been produced from the well, and it is more representative of the
formation water.
The U.S. Geological Survey analyzed the samples for tritium content.
The values reported for both samples were below 300 tritium units, the
detection level for the analytical method used.
