The non-degradation of conductivity during the productive life of the well is crucial for a good production performance. There are different mechanisms of fracture conductivity degradation among which we can name embedment, crushing and spalling. In the present work the effect of the different variables that governs these phenomena are studied by numerical geomechanical simulation. In particular, proppant-formation contact and the exposed face of the fracture during production are simulated in detail analyzing the spalling phenomena. Based on these studies, first, the phenomena present in the fracture conductivity tests are compared to those that occur in hydraulic fractures during the well productivity. Finally, recommendations for drawdown management are generated aimed to preserve the health of hydraulic fractures in order to maximize production performance.
