Seepage Mechanisms and the Development of CO2 Injection in Sandy Conglomerate Reservoirs

This comprehensive volume delves into the critical domain of petroleum engineering and rock mechanics, specifically addressing the complex challenges of developing tight conglomerate reservoirs. It presents a systematic exploration of multi-scale pore structures and non-linear seepage behaviors using advanced visualization techniques, such as micron-CT scanning combined with microfluidic chips. These methods offer a unique, real-time view of fluid occurrence and migration, particularly regarding supercritical CO2 injection—a pivotal topic for both Enhanced Oil Recovery (EOR) and Carbon Capture, Utilization, and Storage (CCUS). Through rich illustrations, detailed experimental data, and integrated geological-engineering models, the text analyzes the specific geological characteristics of the Mahu Sag to provide actionable solutions for issues related to strong heterogeneity and reservoir sensitivity. By offering theoretical foundations and practical parameter optimizations for hydraulic fracturing and gas injection, this work helps professionals maximize recovery efficiency in difficult-to-produce reserves. Potential readers include petroleum engineers, geologists, reservoir simulation specialists, researchers in rock mechanics and CCUS, and graduate students focusing on unconventional oil and gas development.
