“According to the latest report, China has a huge amount of low rank coalbed methane resources, and the coal reservoirs in the Jiergalangtu block of the Erlian Basin have the characteristics of "six lows and one thickness". In response to the development difficulties, experts have developed a low rank horizontal well energy gathering segmented volume fracturing technology, which has been successfully applied to the JP1 well, with a daily gas production exceeding 4000 cubic meters, providing a new solution for the efficient development of low rank coalbed methane in China.”
