ANALYSIS OF SAND PRODUCTION CONTROL IN A MATURE OIL RESERVOIR THROUGH ELECTRICAL WELL PROFILES

The sand production happens when the reservoir begins its productive life, and the consolidation of the grains that compose the framework of the oil-producing formation is not enough to keep them cohesive. The front of the drag force is caused by the flow of fluids inside the pores of the rock-reservoir. Therefore, reservoir parameters must be analyzed to observe how they behave considering the production of solids. The operational parameters used in this study were compressional wave, shear wave and gamma ray profiles, depth, average overburden density, reservoir fluid pressure, and bottom pressure in flow during production. These data allowed us to predict the production of sand in a mature oil reservoir. The results show that in the zones that presented solids production, through the control of the dynamic pressure, it is possible to control the production of sand and determine the critical point of its production.
