Significance We present an experimental investigation on the coalescence of hydraulic fractures in a brittle solid. Using a dual-fracturing setup, we obtain high-resolution experimental measurements on the time evolution of the fracture profiles and internal velocity field before, during, and after fracture coalescence. These measurements show an intermediate time self-similar coalescence during the dynamic interaction of two fractures. The work probes the dynamic formation of a fracture network, which is crucial to the industrial practice of energy resource recovery, compensation grouting, and the reservoir integrity of many confined systems involving fluid injection.
