Oshamambe natural gas field had been surveyed geochemically and geologically by the Geological Survey of Japan in 1953 and 1954.The writers performed the core analysis and lift test of natural gas well, Oshamambe R-1, which was drilled under planning of Oshamambe town-office, having 600m of depth and being located about 200m north from Oshamambe station.As a casing pipe, gas-pipes 4 inches in diameter are used about 500m of length. The gas-pipe was perforated between 350-390m, 410-550m in depth, and non-casing bore hole in adepth of 551-613m.The production data obtained under natural flowing are as follows: gas volume water volume water temperature 350-400m3/d 710m3/d 49.0°CAnd the data obtained by the lift test are as follows gas volume water volume water temperature 850-900m3/d 1, 150-1, 200m3/d 50.0°CThe geothermal gradient of this place is almost twice in ordinary region.As a conclusion, the writers suppose that the promising gas-reservoir beds in the Kuromatsunai formation of Pliocence age exist probably in the deeper part than 600m in depth.
