Abstract

This chapter begins with the investigation of the effect of repetitive shocks. In order to investigate the effect of repeated shocks, it considers the experiments on hollow cylinders under high confinement. The chapter examines the capabilities of electrohydraulic fracturing on representative geometries. Next, it reviews simulations using representative reservoir geometries. After an evaluation of the range of propagation of damage in the context of single shocks, the chapter also looks at an optimization of the process, essentially at the effect of guided pressure waves. Finally, it investigates the influence of the shape of the pressure wave on the extent of the damage. The elastic energy carried by the pressure wave is distributed in a growing volume as it propagates. Therefore, the amplitude of the pressure decays rapidly, and the pressure quickly becomes too low to generate any damage.
