3.6 LABORATORY ANALYSIS

The Laboratory Analysis Task will provide information required for
development of ATES facility design, operation, and maintenance guidelines.
Characterization of the mineralogy, ground-water chemistry, thermal diffu-
sivity, fluid-flow properties (permeability, porosity), and thermomechanical
properties (compressibility, friability) is essential for ATES site evalua-
tion, selection, and operation. Such data are also required for numerical
Laboratory analyses can be of assistance in assessing operational prob-
lems like reservoir clogging and environmental problems like ground-water
quality changes. Example studies include: particulate plugging, clay swell-
ing and dispersion, rock-fluid incompatibilities, fluid-fluid incompatibili-
ties, temperature-dependent mineral dissolution and precipitation, creep
compaction, oxidation reactions, and gas exsolution.
The following laboratory support work was conducted in FY-1980:
. Design and construction of the STES Laboratory Flow Facility were begun.
. Generic investigation of temperature-induced permeability alterations and
creep compaction was begun.
. Design was completed and construction began on the Mobile Injectivity
The STES Laboratory Flow Facility will provide for testing of generic and
site-specific aquifer/aquiclude media under simulated field conditions includ-
ing time varying stresses, temperature, flow directions, flow rate, and brine
chemistries. Measurables include sample strain (deformation), permeability,
porosity, viscosity, pH, and dissolved and suspended constituent chemistry.
