A New Foam Fracturing Fluid for CBM Reservoir
Abstract:
A new foam fracturing fluid composed of sodium dodecyl sulfate (SDS), fluorocarbon surfactant (FCS-11), viscoelastic surfactant VES is proposed and developed in this paper. The performances of this fracturing fluid were systematically investigated. The experimental results show that this foam fracturing fluid has good shearing resistance, viscoelasticity and stability. And above all, once broken it has no residue and the damage rate is only 10.12%. These advantages give it a wide application prospect in coal bed methane development.
