Parameter Sensitivity Analysis of the Hydraulic Fracture Growth Geometry in a Deep Shale Oil Formation: An Experimental Study

Table 1

Comparison of true triaxial hydraulic fracturing experimental fracture monitoring methods.

Monitoring method	Advantages	Disadvantages
Open samples directly [26]	Hydrofracture plane morphology can be directly observed with tracer	It is difficult to obtain three-dimensional fracture morphology of samples; it is difficult to distinguish hydraulic fractures from natural fractures
CT scanning [27]	The distribution of three-dimensional fracture network can be reconstructed without destroying the sample	Poor application effect for large size samples; it is expensive and economical
