The report presents the results of geomechanical and CT-based studies on deformation, fracturing, and filtration processes in reservoir rocks of a gas-condensate field on the Arctic shelf. The study integrates true triaxial physical modeling, hollow cylinder sand production tests, triaxial geomechanical experiments, and digital CT analysis of the rock matrix and sand particles to assess wellbore stability and sand control strategies. The research determined the relationships between permeability, rock deformation, and stress conditions around a horizontal well during drawdown. Hollow cylinder-type tests identified the critical stress thresholds for sand production initiation, sand production intensity under varying stress conditions, and the total volume of produced sand. Digital particle size analysis provided insights into the dominant failure mechanisms of wellbore walls during sand production.
