Investigation Of The Stability Of Liquid And Air Films By Synchronized Tri-Wavelength Reflection Interferometry Microscope, Yuesheng Gao
Investigation Of The Stability Of Liquid And Air Films By Synchronized Tri-Wavelength Reflection Interferometry Microscope, Yuesheng Gao
Dissertations, Master's Theses and Master's Reports
Liquid films are widely involved in many processes, such as froth flotation, oil extraction, foam/bubble stabilization, etc. In the meantime, air films are commonly seen in diverse fields like dust control, ink print, coating industry, and so on. Stabilities of these liquid/air films are of great importance to improve the processes. As more and more researchers are paying increasing attention to liquid/air films, tremendous efforts have been made to explore the properties of the films. On the one hand, some theoretical models have also been well developed in recent decades. State-of-the-art technologies, such as AFM, SFA, and RICM, have also …
A Petrophysical Evaluation For Permeability Of A Gas Reservoir In The Taranaki Basin, New Zealand, Musa Cetin
A Petrophysical Evaluation For Permeability Of A Gas Reservoir In The Taranaki Basin, New Zealand, Musa Cetin
Dissertations, Master's Theses and Master's Reports
The goal of this study was to evaluate permeability and study the controls on permeability in a gas saturated formation. Conventional well logs, mineral identification crossplots and empirical models were applied to analyze different lithologic and diagenetic features and to examine the effect that these features may have on the reservoir. An unusual feature was observed, and required detailed examination: there existed (in two wells) five zones of lower resistivity (higher water saturation) above the gas-water contact. This is unexpected, as above that contact, the water is usually at irreducible water saturation. I conclude that the lower resistivity (the higher …
