Nov 22 (LNGJ) - Royal Dutch Shell said it planned to invest $1 billion a year in its upstream businesses in China, a move based on the country's surging natural gas consumption. Among several projects, and in cooperation with Sinopec, Shell is developing two shale-gas blocks, Jinqiu and Fushun-Yongchuan in Sichuan province, an area in the country found so far to have the largest shale reserves.
