Attenuation induced by squirt-type mechanisms has previously been analyzed for aspect ratios smaller or equal to 103. Using a hybrid-dimensional modeling approach, particularly apt for large aspect ratio conduits, we numerically simulated deformation-induced fluid flow along two intersecting fractures to investigate the physics of attenuation related to the interaction of fracture-induced fluid flow and to leak-off. Attenuation related to fracture flow increases in magnitude with increasing geometrical aspect ratio of the fracture. The inherent time scales of both flow mechanisms do not influence each other, but the faster process is associated with stronger attenuation than the slower process. Models relying on simple diffusion equations have rather limited potential for approximation of pressure transients.
