Abstract
In this work the fluid dynamics of the lost circulation phenomenon and particulate systems for the process of filling fractures is investigated experimentally. The experimental set-up comprises a rectangular test section with a transverse fracture, instrumented with pressure gauges, flow and temperature monitors. In order to characterize the fracture filling pattern, the influence of variations of the particle type and concentration, the fracture thickness, the fracture outlet initial flow rate and the Reynolds number along the position, length and height of the formed bed of particles is investigated. The particulate flow is represented by a solution of water-glycerin with solid particles, abrasive plastic and glass spheres are used. Results show that all the parameters present the ability to modify the geometric characteristics of the bed, having a direct influence on the filling time and the fluid lost by the fracture.
