Characteristics and Origin of Methane Adsorption Capacity of Marine, Transitional, and Lacustrine Shales in Sichuan Basin, China

Figure 7

Comparison of shale adsorption capacities of Sichuan Basin and North America. The adsorption capacity of 5 sets of shales in Sichuan Basin is higher than that in North America. (Part of data is from Reference [12, 14]). Red points represented shale adsorption capacities of Sichuan Basin, and blue points represented that of North America. Besides, the era of different Formation was labelled in following parentheses.
