New analytical model of plugging zone strength for drill-in fluid loss control in fractured reservoir. Sensitivity analysis of mechanical and geometric properties of loss control material (LCM) on plugging zone strength. Single LCM parameters for selection of LCM type; plugging zone parameters for determination of optimal LCM concentration. Combination of rigid granule, fiber and elastic particle for synergy effect on optimizing plugging zone strength. Developed application procedure to drill-in fluid loss control successfully applied to field case study.
