The study program of the MH21 research consortium for methane hydrate resources in Japan was concluded in 2019 with many outcomes such as the world’s first offshore production test (2013). However, the achieved production rates still fell short of the economical criteria. The analyses and evaluations of the obtained data and experiences revealed some important factors such as excess water production and formation damages around wellbores. The newly started phase 4 study focuses on the development and verification of technologies that solve the technical challenges.
