Sand production is a major challenge in oil and gas operations, particularly in unconsolidated sandstone reservoirs. Among various sand control techniques, chemical methods such as resin-based consolidation and sand conglomeration have emerged as promising solutions due to their flexibility and ability to be applied in complex well configurations. This study focuses on evaluating the technical and economic performance of sand conglomeration as a chemical sand control method and comparing it with conventional resin treatment. Using actual field data for both gas and oil wells, technical simulations were carried out using PROSPER software to model well performance before and after treatment. The analysis included sensitivity studies, skin factor evaluation, and production rate forecasting. Results indicate that while both methods are capable of reducing sand production, sand conglomeration consistently provides better economic outcomes. In the first 30 days of production, sand conglomeration showed a lower profit reduction compared to resin, especially significant in gas wells, where resin treatments resulted in a profit loss of up to 258%, compared to 185% with sand conglomeration. For oil wells, profit reduction was 40% with resin and 33% with sand conglomeration. These findings highlight the superiority of sand conglomeration in maintaining productivity while minimizing operational costs, making it a more attractive and field-friendly option for early-stage sand control applications.
