3.4 FIELD TEST FACILITIES
D. A. Myers, Task Leader
Pacific Northwest Laboratory
P.O. Box 999
Richland, WA 99352
A major task under the Technical Support Program is to develop one or
more Field Test Facilities (FTF). The FTFs will be used to test heating
and/or chilling technologies for energy storage in aquifers. The FTF is the
forerunner of demonstration projects for aquifer thermal energy storage. As
a forerunner, the facility will assist in the development of energy storage
technology through research and development activities.
The Field Test Facility Task will manage contracts for field experiments.
The task has been developing a test requirements plan to serve as a basis for
evaluating FTF experiments.
Using the test requirements plan, an FTF experiment was designed to use
the Pasco Gravels aquifer underlying the area near Richland, Washington.
Drilling specifications were developed and potential drill sites were evaluated
under the constraints of current land use and ownership. Seven exploratory
drill sites were selected. The shallow, unconfined nature of the Pasco Gravels
aquifer minimized the need to obtain highly specialized drilling contractors.
The drilling contract was awarded to a local driller of domestic and irrigation
wells. Seven wells were drilled to depths of 70 ft. The aquifer was highly
variable in water bearing characteristics over very short distances. Well
yields ranged from about 5 gpm (gallons per minute) with excessive drawdown to
over 200 gpm with drawdowns of only 0.15 ft. This variability in aquifer
characteristics limits the usefulness of the Richland FTF site for thermal
injection and storage. Future plans for the site are limited to isothermal
experiments involving gradient control and injectivity in shallow unconfined
