Japan: Short-Term Flow Tests at Akita Geothermal Energy Project Carried Out

INPEX and Partners to Conduct Short-term Flow Tests on Exploratory Well
for Geothermal Power Generation in Akita Prefecture, Japan (News Release)

INPEX Corporation announced today that it will conduct short-term flow tests to gauge the capacity of exploratory wells it has drilled in the Oyasu region of Akita Prefecture, Japan in partnership with Idemitsu Kosan Co., Ltd. and Mitsui Oil Exploration Co., Ltd., with which it has jointly pursued commercialization studies on geothermal power generation since 2011.

The short-term flow tests will be conducted on two exploratory wells drilled during the current fiscal year. The tests will evaluate production capacity based on a constant flow over a 1~2 week period using wells similar in size to actual production wells. Through these experiments, the companies will verify details concerning well production capacity (volume of steam), underground temperatures, chemical composition of geothermal fluids, water permeability in the vicinity of the well and other matters.
