Problem Statement
- Conventional fracking methods may not effectively maximize the recovery of oil & gas from depleted wells, limiting the efficiency of the extraction process.
- Existing techniques might struggle to sufficiently elongate perforations or create new cracks within the well bore, restricting the productivity potential of the well.
- The inability to access & release the remaining trapped oil and gas from reservoirs, hydrates, or shales using current fracking methods poses a significant challenge in maximizing resource extraction.
- Hence, present invention is needed to optimize and enhance the recovery of oil and gas from depleted or low-producing well bores.
Technology
- The instant patented technology discloses a system designed to generate shock waves in a well bore, primarily for enhancing oil and gas recovery.
- This technology innovatively uses a dual-layer diaphragm design and controlled explosions to generate focused shock waves, effectively enhancing oil and gas recovery in well bores while ensuring safety and cost-effectiveness.
Components:
- Versa Fracking Gun: Cartridge, Gas-Filled Cylinder, Explosive Pods and Charges, Detonator, Valves
- Coupler: Connects the versa fracking gun to an external unit via a wire line. Isolates the wire line to protect it during explosive operations.
Innovative Features:
- Dual-Layer High-Stress Concentration:
- The cartridge and gas-filled cylinder have specific regions designed for high stress concentration.
- Overlapping these regions creates a dual-layer diaphragm for focused and unidirectional shock wave generation.
- Explosion and Shock Wave Generation:
- Controlled explosions within the gas-filled cylinder result in immediate pressure differences between the cylinder and the well bore.
- Rupturing the dual-layer diaphragm generates shock waves directed towards existing perforations or to create new fractures, followed by negative blast waves.
- Wire Line Isolation and Safety: The coupler prevents damage to the wire line during explosions by isolating it from the fracking gun.
