Siliceous Hard Shale
• Akita-Yamagata Basin has highly potential for shale oil (tight oil) and shale gas.
• Siliceous shale of Onnagawa Formation is important shale Formation.
• Equivalent or similar lithologic formations are distributed in Niigata, Okushiri, Oshima and Teshio basins.

Ayukawa Oil-field As the 1st step, we tried acid stimulation in a existing deviated hole
Success!
Fukumezawa Oil-field A multi-stage hydraulic-fracturing project with a horizontal well.
The 1st pilot test for shale oil in Japan, Operated by JAPEX and sponsored by JOGMEC
（Joint study with JOGMEC since 2013～2017） multi-stage fracturing in a horizontal well in FUKUMEZAWA ⇒ application of the standard technology to Japanese Monterey-type shale

Ayukawa Oil-field As the 1st step, we tried acid stimulation in a existing deviated hole
Success!
Fukumezawa Oil-field A multi-stage hydraulic-fracturing project with a horizontal well. (under flow-back)
Test was Finished in 2017 (Success?) Current Producion Production (1 well) : Oil : 10kl/day (62.9bbl/day) Gas : 2,000m3/day
The 1st pilot test for shale oil in Japan, Operated by JAPEX and sponsored by JOGMEC
Estimation of Tight Oil Reserves (after Dr. S.Yokoi, JAPEX )
• Ayukawa Area : simply 2 million bbl
• But no Commercial Product -> difficult to estimate proven play
• Adapting Rock-Eval Using Downey et al.(2011) Metord
Thank You for your attention
