AI Technical Summary
Technical Problem
Conventional shaped charge perforating guns are single-use, leading to significant waste, environmental impact, safety risks, and inefficiencies due to high-explosive materials, and they struggle with achieving consistent perforation geometry and dimensions in well casings.
Method used
A reusable charge dispenser system for perforating guns that uses propellants instead of high explosives, allowing for controlled combustion and multiple uses, and is designed to create uniformly cylindrical perforations.
Benefits of technology
The system reduces waste, minimizes environmental impact, enhances safety, and achieves consistent perforation geometry, improving hydraulic fracturing efficiency by ensuring uniform fluid flow, stress distribution, and fracture propagation.
