Chemical Prospecting Of Steam And Hot Water In The Matsukawa Geothermal Area
Journal Article: Chemical Prospecting Of Steam And Hot Water In The Matsukawa Geothermal Area
AbstractIn the Matsukawa geothermal area, the first experimental well, AR-1, was drilled in 1960, and the sixth production well, No. 6, was completed in January, 1969. During this period, chemical investigations, hourly variations and relations of interference of the steam and hot water from every well have been continued. The steam of Matsukawa is classified into three types according to the physical characteristics such as the degree of moisture and existence of hot water. Chemically, it is classified in two types according to the composition of the steam. As for the content of hydrogen sulfide in the steam, we cannot make a distinct classification as above, but it was found that the shallower wells tend to contain more hydrogen sulfide. Regarding the interference among wells in Matsukawa, drilling a new well did not cause any decrease of the steam amount in former wells. With regard to the discharge of hot water, however, interference was observed between No. 1 and No. 4 wells, and No. 1 and No. 5 wells. Interestingly enough, the interference was only one way, that is, there wasn't any interference from No. 1 to No. 4, nor No. 1 to No. 5, (but there was one from No. 4 and No. 5 to No. 1). Various tests were made on the hot water which suggests the type of steam reservoir and has a great influence upon the type of steam as well. The following are the reports of our investigations made from a chemical view point.
