Results of comparative experiments with different ahead fluid.
| Experiment | Tri-axial pressure (MPa) | Experimental fluid | Degree of fracture diversion | Relationship between hydraulic fracture and natural fracture | Fracture complexity | |
| 2 | 25/20/10 | | High | Crossing | High | 3 | 25/20/10 | | Low | Diversion | Low | 4 | 25/20/10 | | High | Diversion | Medium |
