Numerical simulation of spatial-braided bow-shape well pattern development in shallow tight reservoir

, 2021
In shallow tight reservoirs, the hydraulic fracturing tends to produce horizontal fractures. For the horizontal wells, multi-stage fracturing is easy to generate only one large horizontal fracture, which leads to poor stimulation effect.
