Description

This comprehensive engineering course delivers end-to-end technical training on executing zonal isolation and squeeze cementing operations utilizing coiled tubing (CT) units. Well intervention engineers, supervisors, and operations personnel will gain a thorough operational understanding of how to prevent unwanted water, gas, or oil production across targeted intervals and restore reservoir flow efficiency.The curriculum begins with core definitions and operational classifications, covering the critical properties of primary isolation materials including squeeze cement, mechanical resins, and shear-sensitive polymers. Participants will study the chemical and physical mechanics of each system, examining rock matrix placement dynamics, viscosity behavior, and setting characteristics under bottomhole conditions. Learners will explore advanced job design principles, focusing on diversion techniques and the deployment of stable retaining platforms like through-tubing bridge plugs, high-density fluids, sand beds, and calcium carbonate to avoid slurry slumping. The technical modules guide participants through surface equipment layout, reel manifold sampling systems, pressure control equipment (PCE), and downhole bottom-hole assembly (BHA) design. Detailed operational guidance is provided for tubing end locators (TEL), dual flapper check valves, plug catchers, and specialized jetting nozzles.Finally, the course walks through live execution workflows: accurate depth correlation, spacer design to eliminate slurry contamination, dynamic placement while pulling out of hole (POOH), and high-pressure squeeze cycles. Attendees will master cleanout methodologies—including conventional and reverse circulation of live or contaminated cement—followed by safe rig-down, top of cement (TOC) tagging, wellbore drifting, and high-differential integrity testing.
