Abstract

Hydraulic fracturing stimulation has become a routine for the development of shale oil and gas reservoirs, which creates large volumes of fracturing networks helping the hydrocarbon to transport quickly into the wellbore. However, the optimal fracture spacing distance and fracture conductivity are still unclear for the field practice, even though the technique has improved significantly over the last several years. In this work, an analytical method is proposed to address it. Firstly, the analytical production rate for a single fracture is proposed, then we apply Duhamel principle to obtain the production rate of a horizontal well with multi-fractures. Based on this model, the flow regimes and essential affecting factors including fracture-spacing, fracture conductivity and skin factor are analyzed in this work. The optimal values and suggestion are provided based on the simulation results.
