  • Method and device for slotting well casing and scoring surrounding rock to facilitate hydraulic fractures
    Patent number: 5564499
    Abstract: Linear apertures are created in well casing through the use of linear charges lowered into the well casing in place; hydraulic fracturing conducted through the linear apertures achieves larger and less dissipated fractures than conventional small circular perforations which generate near well bore tortuosity. The linear charges can also be used in open bores and in overbalance perforating.
