Practical Evaluation of Sand Consolidation in Oil Wells by Various Methods

Problems of sand migration because of the extraction from oil wells lead to propose some ways for controlling sand migration near the well. In this research, first the proper resins were chosen as the consolidators by studying the resources and evaluating them. After preparing the resins, the necessary phases for making samples were performed. So first a template for making samples was prepared by using pulika pipe. In the first method, the cemented samples were prepared by mixing different kinds of bought resins and different percentages ofsand. In the second method, two resins were chosen for the consolidation and samples were prepared as follows: first a certain amount ofsand was poured into a template and made a sand pack, then the resin and solvent was used for the sand consolidation Finally, permeability rate, porosity percentage and compressive strength of the prepared samples were measured based on the available standard methods. The obtained experimental data showed that for these methods, the permeability, porosity and compressive strength of the core samples are retained in acceptable values.
