(1662) said Thursday it will look into commercializing shale oil production in Akita Prefecture. The Ayukawa oil and gas field in Yurihonjo has harvested a total of 1,419kl of oil in test extractions, approximately 40kl, or about 251 barrels, per day. If production gets off the ground, it will be the first commercially produced shale oil in Japan. The company announced the same day that it will begin the same type of experimental bedrock drilling in Oga, Akita Prefecture. The U.S. is well ahead of the pack in shale oil production. Japex started test drilling in the Ayukawa field last October using acid treatment, in which diluted hydrochloric acid is pumped into the well to melt the rock and make oil easier to extract. It was the first successful shale oil extraction in Japan. Two other extractions followed, in the November-December and May-July periods. Only about 6kl per day were produced the first two times, but the third yielded about seven times that amount. "Acid treatment has generated results over time," the company said. In Oga, Japex plans to drill a new well in the Fukumezawa field as early as next year. The project will utilize hydraulic fracturing, an extraction method in which the well is drilled down to the water table and hydraulic pressure is applied to faults in the bedrock to recover the oil. This has seen success in the U.S., and the company wants to make it a part of drilling technology in Japan as well. (The Nikkei, July 26 morning edition)
