Sumitomo looks set to benefit from US shale boom despite production shutdown, Sumitomo's exit from U.S. shale creation remains as an unmistakable difference to significant energy organizations, including ConocoPhillips and Exxon Mobil, which are making billion-dollar acquisitions with the expectation that interest for oil and gas will stay vigorous even as the world gets some distance from petroleum products. Japanese organizations have joined this pattern: Mitsui and Co. purchased a shale gas resource last month and Tokyo Gas purchased Rockcliff Energy for $2.7 billion last year.
