Molecular weight (MW) distributions of organic matter in the (a) pure HPG (b) simulated fracturing fluid-0 and (c) simulated fracturing fluid. Five MW fractions (<1 kDa, 1–10 kDa, 10–100 kDa, 100–1000 kDa, and>1000 kDa) were identified in the pure HPG, simulated fracturing fluid-0 and simulated fracturing fluid.
