How does one collect pore water samples from coal seams and is there any standard protocol?

07 July 2014 1 7K Report

Aerobic and anaerobic conditions.

Presumably the coal seam is not saturated with water. If it were, then a core will fill with water simply due to the pressure gradient. For an unsaturated coal seam, using a double action pressure swing to first locally infuse the seam with water, then extract it, will obtain enough for later analysis. A device will need to be invented for this purpose to lower into the core, however. The alternative is to extract a core sample and then analyse in the laboratory.
