Gas Dymanics at Pressure

Be expert drilling supervisor of Oil and Gas drilling industry.

This book covers managed pressure drilling (MPD), the role of artificial intelligence (AI) in refining drilling processes, and the transformative effects of digitalization and automation. Emphasizing efficiency, safety, and environmental responsibility, the book integrates methods like casing while drilling for improved efficiency, advanced diagnostics for rig safety, stabilization techniques for wellbores in fractured reservoirs, cement sheath integrity maintenance, and the optimization of continuous gas lift.

This book provides a systematical investigation on the reservoir characteristics and percolation mechanism of ultradeep carbonate gas reservoirs, including reservoir characteristics and classification, gas storage and percolation capacities, gas-phase and gas-water two-phase percolation mechanism, microscale complex gas-water relationship, reservoir sensitivity characteristics, and gas production characteristics of heterogeneous carbonate reservoirs. Some advanced and improved experimental techniques and analytical methods are introduced and applied, including comprehensive evaluation technique of storage and percolation capacities, ultra-high temperature and pressure physical simulation experiment technique, microscopic visualization technique based on CT scanning and microelectronics lithography, and physical simulation technique for heterogeneous reservoir development. In addition, it summarizes strategies for the efficient development of ultradeep carbonate gas reservoirs based on these theoretical research results.

Gas hydrates are ice-like crystalline substances that form a rigid cage of water molecules and entrap hydrocarbon and non-hydrocarbon gas by hydrogen bonding. Natural gas hydrate is primarily composed of water and methane. These are solid, crystalline, ice-like substances found in permafrost areas and deepwater basins around the world.
