Example Permeability Versus Temperature
Curve (Weinbrandt 1975)
Four potential causes for the observed permeability changes are being sys-
tematically explored: 1) sample consolidation or densification, 2) particulate
plugging, 3) anomalous fluid viscosities, and 4) silica complexing with iron
or nickel leached from the test apparatus. A schematic of the experimental
apparatus is shown in Figure 3.6.2.
Information is being acquired on chemical equilibrium constants and reac-
tion rates at temperature for some primary constituents in ground water. For
example, Figure 3.6.3 contains data for quartz, calcite, and hematite at
various temperatures. Figure 3.6.4 shows the time required to achieve 90%
silica saturation in a quartz-water system. Ground-water constituents are
shown in Table 3.6.1. Data are also being collected on thermal conductivity,
thermal expansion, and specific heat capacities.
