Introduction and Historical Perspective:

Natural gas hydrates are crystalline solids composed of water and gas. The gas molecules (guests) are trapped in water cavities (host) that are composed of hydrogen-bonded water molecules. That's a first d

Whatever well functions are being carried out, there are approximately 7 functions which a mud must perform. This is true regardless of which hole section is being drilling, although the emphasis changes in different hole sections. The 7 primary func

Introduction:

Gas transport in a porous medium occurs in several important applications including Oil and Gas exploration, carbon sequestration and some industrial processes involving heat transfer. Understanding the fundamental mechanisms and pr

Energy Consumption Growth

Human development is closely linked to energy consumption. Humans, since the dawn of time, have been able to master different forms of energy and transform them to improve their quality of life. Our ancestors had to rely on
