The scientific novelty lies in the justification of using hydraulic fracturing as a method for creating a consolidated screen that functions as a downhole filter. The proposed approach achieves a negative skin factor while simultaneously stabilizing the formation skeleton. The practical significance is confirmed by the complete elimination of sand production and improved well operation efficiency in shallow depth conditions.</p> <p><strong>Aim: </strong>To demonstrate the first practical experience in Kazakhstan of implementing hydraulic fracturing in an unconventional reservoir – a poorly consolidated, highly permeable formation with high-viscosity oil at shallow reservoir depth.</p> <p><strong>Materials and methods:</strong> This study is based on field data and operational reports from hydraulic fracturing (HF) activities at Field M. Geomechanical and filtration properties of the formation were simulated, and fracture propagation was modeled in the FracPro software using actual injection parameters. The resulting models were compared with the outcomes of the implemented HF treatments, allowing evaluation of the correspondence between design solutions and field performance, as well as analysis of the effectiveness of the conducted interventions. This work represents Kazakhstan’s first practical experience of implementing HF in an unconventional reservoir: a poorly cemented, highly permeable formation containing high-viscosity oil at shallow depth.</p> <p><strong>Results:</strong> The study analyzed the actual HF operations performed on wells at the M field. Modeling of fracture parameters was conducted in FracPro using real-world injection data. Comparing the calculated and actual performance indicators allowed for the evaluation of treatment efficacy, validation of achieved production rates against design expectations, and identification of key result-influencing factors. A comprehensive analysis was also performed of the geological and technical conditions, reservoir structure, and initial filtration-capacitance properties (FCP) of the formation. Key factors affecting the results included the selection of the optimal concentration of the adhesive composition for proppant consolidation and the control of net pressure during the injection process. Practical recommendations were developed for optimizing the design and execution of HF in reservoirs at depths below 500 m.</p> <p><strong>Conclusion: </strong>The findings confirm the necessity of further optimization in HF design and execution at the M field, particularly regarding the refinement of injection parameters and correction of the model’s filtration-storage characteristics. This comprehensive analytical approach not only improves the efficacy of already performed treatments but also forms the basis for selecting optimal candidates and enhancing HF design in future projects.</p>hydraulic fracturingsand productionfilterfrequently repaired well stockworkover intervaldata analysisHF efficiencyқабатты гидравликалық жаруқұмның пайда болуысүзгіжиі жөнделетін қоржөндеу аралық кезеңдеректерді талдауҚГЖ тиімділігігидравлический разрыв пластапескопроявлениефильтрчасто ремонтируемый фонмежремонтный периоданализ данныхэффективность ГРП1.Economides M, Oligney R, Valkó P.
