ENHANCING APPROACHES FOR THE EFFECTIVE DEVELOPMENT OF COMPLEX MULTILAYER NATURAL GAS FIELDS: A COMPARATIVE STUDY

Abstract

Multilayered natural gas fields represent a significant portion of global hydrocarbon reserves, yet their development is hindered by complex geological structures, reservoir heterogeneity, and high extraction costs. This study provides a comparative analysis of four major multilayered gas fields: Urengoy (Russia), Galkynysh (Turkmenistan), Haynesville (USA), and East Berdakh (Uzbekistan). The research evaluates the effectiveness of current extraction methods, including hydraulic fracturing (HF), horizontal drilling, and reservoir pressure maintenance strategies. Using a comparative methodology, this study identifies key challenges and proposes optimized approaches to enhance gas recovery factors (GRF). The findings suggest that a hybrid HF approach, AI-assisted digital modeling, and improved well placement strategies can significantly enhance the efficiency of multilayered gas field development.
