FIELD: physics; geophysics.
SUBSTANCE: invention relates to geophysics and can be used to select producing reservoirs, particularly gas hydrate-saturated reservoirs, in well columns. The disclosed method comprises conducting survey through gamma-ray density logging and neutron logging techniques and calculating a porosity factor based on data from either technique. Gas hydrate-saturated reservoirs are selected when values of porosity factors calculated from gamma-ray density logging exceed those calculated from neutron logging.
EFFECT: high accuracy of prospecting data.
