The panel a connects a C O 2 cylinder through P R 1 and valve A to the sample chamber. P R 2 supplies membrane pressure. A gauge monitors chamber pressure. Valves F and B connect the chamber to an accumulator and P R 3, which leads to the fume hood. Valve C and B P R 1 connect to pilot reference pressure. Valve D connects to the lower chamber line. The panel b connects a reservoir through valve E to a Quizix pump, then through valve A to the chamber. Valve G supplies pressure to the jacks, while P R 2 supplies the membrane. Valves F, K, B and C connect the chamber to B P R 1, pilot reference pressure and a Carboy leading to the fume hood. A second Carboy connects through B P R 2 and valve D to the chamber. The panel c connects pump A to three N 2 dead oil accumulators maintained at 40 to 45 degrees Celsius, then through valve A to the chamber. Valve G supplies the jacks and P R 2 supplies the membrane. B P R 2 and valve D connect a Carboy and pilot reference pressure to the chamber. Valves F, K, B and C provide additional chamber connections.Schematic diagrams of the staged saturation procedures used for GeoTriax specimen preparation: diagrams of (a) CO2 saturation, (b) water saturation, and (c) dead oil saturation
