Experimental near-wellbore hydraulic fracture initiation and growth for horizontal wells with in-plane perforations

To understand the fracture behavior during different perforation modes on horizontal wells, laboratory-scale hydraulic fracturing experiments with acoustic emission monitoring were conducted on tight concrete samples. The experimental results indicated that the breakdown pressure could be greatly reduced and that a simple fan-like structure was created with in-plane perforations on a horizontal well under the same fracturing treatment...
