Given the rapid pace of technological advancement and the growing need to optimize production processes, the relevance of studying new types of proppants becomes obvious. The ability to model and customize high-tech proppants for the specific conditions of oil fields is crucial for enhancing hydraulic fracturing efficiency and, as a result, boosting hydrocarbon production volumes in the Atyrau region.</p> <p><strong>Aim:</strong> This article discusses recent advancements, global trends, practical experience, and laboratory studies related to the use of innovative proppants. It also evaluates the potential for utilizing lightweight proppants at fields A and B. The aim of this study is to explore the possibilities of deploying multifunctional proppants to optimize hydraulic fracturing operations.</p> <p><strong>Materials and Methods:</strong> To address the set objectives, we developed a model of the geomechanical and filtration properties of the formation for fields A and B using FracPro software. Also, we conducted a simulation of the hydraulic fracturing design with various injection parameters . Based on the results of hydraulic fracturing modeling results using lightweight proppants, we calculated indicators oil production .</p> <p><strong>Results:</strong> The simulation results demonstrate the economic feasibility of using lightweight proppants, evidenced by a 23.8% increase in additional production at Field A. For Field B, the estimated annual production volume significantly exceeds current levels, resulting in a 4.5-fold increase in profitability.</p> <p><strong>Conclusion:</strong> Multifunctional proppants hold considerable potential to enhance hydraulic fracturing efficiency. The application of innovative proppants allows for better control over fracture geometry, minimizes the risk of breakthrough into water-saturated zones, and increases the volume of stimulated zone, thereby optimizing hydrocarbon production.</p>hydraulic fracturinglightweight proppantfractionscoatingmodelingfractureқабатты сұйықтықпен жаружеңілдетілген проппантфракцияларжабынмодельдеужарықшақтаргидравлический разрыв пластаоблегчённый проппантфракциипокрытиемоделированиетрещина1.Smith M, Montgomery C.
