Based on the results of laboratory and field tests of formation hydraulic fracturing (FHF) some basic factors are defined which influence upon the effectiveness of FHF technology involved the injection of large quantities of sand into the formation. These factors include a no strictly orthogonal trajectory of FHF fracture; abrasive destruction of initially round perforations; off-center positioning of quashhead shells inside the casing; sphericity and roundness of the proppant (sand) particles, etc.
