Complex perforating charge
Designed for performing cumulative perforation simultaneously with high-energy impact on the reservoir, improving the connection between the wellbore and the reservoir in oil and gas wells to increase the flow rate of oil and gas and/or injectivity in wells.
Consists of a standard shaped charge and a gas-generating charge containing a high-energy explosion cartridge. Installed in a standard perforation system.
Operating principle:
A charged perforator is lowered into the wellbore on cable or tubing. The perforator is initiated at a predetermined interval. After the cumulative jet penetrates the channel in the casing and reservoir, a pressure pulse from the gas-generating charge impacts the channel walls, creating an additional network of fractures, thereby increasing the quality of secondary opening.
Key benefits of the complex perforating charge:
combining the creation of perforation channels with the increase in reservoir permeability results in reduction of time and costs without compromising safety.
uniform opening of horizons, increase in the contact area of the well and the layer, effective access to resources and reduction of risk of damaging the bottomhole zone.
reduction in the number of stages and downtime, reduction of labor costs while maintaining high level of safety.
natural completion of wells, restoration perforation (restoration of the flow rate of existing wells), flooding of injection wells (maintaining reservoir pressure), preparation for hydraulic fracturing (increasing the efficiency of hydraulic fracturing).
