An apparatus and method for perforating and fracturing subterranean formations to enhance fluid production. At least one unlined punch charge is loaded into at least one punch charge carrier (26), and the void spaces in the punch charge carrier are filled with sand. The punch charge carrier is assembled with at least one perforating charge carrier (32), loaded with at least one perforating charge, and a means for detonation. The assembly is positioned in a well containing a pressurized fluid adjacent the interval to be perforated and/or fractured, and the charges are detonated. The one or more punch charges create one or more apertures in the punch charge carrier, allowing sand to enter the well and be carried by the fluid in the well into the perforations and/or fractures created by the perforating charges and the pressurized fluid. The sand scours and/or props the perforations and/or fractures.

Dispositif et procédé de perforation et de fracturation de formations souterraines, afin d'améliorer la production d'hydrocarbures. Au moins une charge de perçage non tubée est chargée dans au moins un support de charge (26) de perçage et les espaces vides dudit support sont remplis de sable. Le support de charge de perçage est assemblé avec au moins un support de charge (32) de perforation contenant au moins une charge de perforation, ainsi qu'un moyen de mise à feu. L'ensemble est placé dans un puits contenant un liquide sous pression contigu à l'intervalle à perforer et/ou fracturer et les charges sont mises à feu. La charge ou les charges de perçage créent une ou plusieurs ouvertures dans le support de charge de perçage, ce qui permet au sable de pénétrer dans le puits et d'être introduit par le liquide contenu dans le puits dans les perforations et/ou les fractures créées par les charges de perforation et par le liquide sous pression. Le sable affouille et/ou étaye les perforations et/ou les fractures.
