One of the main causes of sand production is the rock faulting, situation that is given by the stress condition, pressure and mechanical properties that is applied. We use geomechanical criteria for the design of gunfire (density, diameter, penetration, phase and drop pressure for cleaning, etc.). It is possible to generate stable conditions that reduce the risk of the rock failure.
Therefore, identified some geomechanical criteria to determine areas of highest stress contrasts, which can accelerate the rock failure, areas with increases in stresses for proximity effect between canyons, among others, must be taken into account in the perforating operations in areas susceptible to sand production, in order to reduce the risk of the rock failure and start early sand production. With the aid of geomechanical models and these criteria it is possible elaborate a methodology for optimal perforating design.
