Abstract
In general, in one aspect, the invention relates to a method for evaluating a volcanic reservoir formation having volcanic rock forming elements and a borehole penetrating the volcanic reservoir formation. The method includes controlling chlorine concentration in an environment of the borehole and a tool operation to enable neutron capture spectroscopy measurements of the volcanic rock forming elements, obtaining neutron capture spectroscopy data relating to the volcanic rock forming elements from borehole logging tools, determining a lithology of the volcanic reservoir formation based on at least the neutron capture spectroscopy data, and generating an evaluation of the volcanic reservoir formation based on at least the lithology.
