Abstract: A downhole hydraulic fracturing system and method utilizing downhole pressure pulsing to enhance fracture propagation, proppant transport, and reservoir permeability. The system employs a hybrid fracturing approach that integrates conventional hydraulic fracturing with downhole pulse hydraulic fracturing. This hybrid technique reduces surface energy demands, enhances fracture initiation, increases fracture density, and improves proppant distribution, thereby maximizing reservoir permeability and overall production efficiency. The system is configured to include: a mechanism that enables real-time, surface-controlled adjustment of pulse intensity; a downhole system capable of generating self-sustained pulsing independent of tubular movement, a downhole sensor system configured to detect, record, and analyze downhole fluid pressure and other critical parameters and additional embodiments that enhance energy transfer efficiency, increase fracture complexity, and optimize proppant transport.

Abstract: A vibrating downhole tool includes a housing having a central axis defined therethrough, an inner mandrel disposed within the housing and configured to receive a drilling fluid, wherein the inner mandrel is misaligned relative to the housing central axis, and a plurality of turbine blades configured to receive the drilling fluid and to rotate the inner mandrel, thereby causing the downhole tool to vibrate.
