Thermochem services

Each stage of geothermal energy development is dependent on geochemistry data. Samples of water and gas from greenfield exploration, reservoir production, power plant emissions, and reinjection all play a key role in the ultimate goal of geothermal power generation. Each sampling application requires specialized techniques for accurate sample collection and preservation, and trained personnel to perform the sampling.

Geothermal Well Testing has traditionally been performed using atmospheric cyclone separators with a James Tube at the inlet to measure total mass flow and a weir box at the outlet to measure brine flow (Figure 1). The James Tube calculation requires enthalpy as an input which can be determined by iteration of the total mass flow and the separated brine flow. This technique has been used without modification or improvement for over 40 years (James. 1966). Accuracy estimates for total mass flow by this method range from +/- 5 to +/- 25% (Jung, 2001).
