Figure 4.
The first view presents the assembled apparatus with chamber 1, the upper chamber, and chamber 2, the central chamber. Parker motor A connects to piston B, which moves hydraulic oil across the cap. The cutaway identifies chamber 1 as the upper chamber, chamber 2 as the central chamber and chamber 3 as the lower chamber. Parker motor A drives piston B above cap C. Membrane D spans the upper region of the central chamber. Remotely activated wellbore E extends vertically through the sample region towards activator F. Pressure transducer G mounts near the wellbore base. Sand-trap H occupies the lower chamber.Whole and internal sectional view of the GeoTriax cell highlighting the principal components
