Abstract

The use of foam-based fracturing fluids for hydraulic fracturing has been identified as a promising technique to extract unconventional natural gases. However, lack of knowledge of foam properties and the two-phase flow behaviour of foam under high pressure makes it challenging to use in field conditions. Therefore, this comprehensive study was conducted to investigate (1) the properties and flow behaviour of foams, under relatively high-pressure (7 MPa) conditions using a newly-developed high-pressure viewing window and (2) two-phase flow behaviour through fractured rock using the high-pressure triaxial test apparatus. Fracture permeability tests were conducted for a series of confining and..
