对日本新泻和茂原气田进行了微生物研究。从300 ~ 800 m深度的天然气卤水中分离到了大量的好氧细菌，主要属于假单胞菌属，而在1000 m以上深度的天然气卤水中则很少或没有发现微生物。分类学研究表明，在三年期间，在气井威尔斯中发生了微生物区系的演替，从只有少数微生物到大量的荧光组假单胞菌。由此推断，大量淡水可能从外部侵入气层，在新泻气田中，淡水可能从东北向西南流动。与油卤水相比，新泻气田气卤水中未发现煤油利用菌和厌氧硫酸盐还原菌。茂原气田卤水中未发现微生物。建议在天然气开采和石油开采中使用细菌示踪剂。
Microbiological studies on the Niigata and Mobara gas-fields in Japan were carried out. A considerable number of aerobic bacteria, mainly belonging to genus Pseudomonas, were isolated from the gas-brines of a depth of 300m to 800m, but few or no microorganisms were found in depth over 1, 000m. Taxonomic studies revealed that a succession in the microflora took place in the gas wells during the three years from only a few microorganisms to a large number of pseudomonads of the fluorescent group. It was deduced from these facts that large amounts of fresh water may invade into the gas-layers from the outside, and that the water may flow from the north-east to the south-west in the Niigata gas-field. In comparison with the oil-brines, it was interesting that no kerosene-utilizing bacteria or anaerobic sulfate-reducers were found in the gas-brines in the Niigata gas-field. No microorganisms were found in the gas-brines in the Mobara gas-field. The use of bacterial tracers for natural gas mining, as well as for petroleum mining, is suggested.
