Could you remind us or define how is energy increased or decreased among the surface molecules? this would be great, before going on to talking about interfacial interactions(breakage/formation of bonds).
The easiest way to see the energy change on creating and interface is to consider the molecular interactions first in bulk. Here the fluid can interact with neighbouring molecules in all directions. When an interface is created, molecules at the surface can only interact with half as many molecules of the same fluid. This is less energetically favourable and is the origin of interfacial tension.
Please email me at m.blunt@imperial.ac.uk and I can give you an electronic version; otherwise you can buy a copy at www.cambridge.org/us/universitypress/subjects/earth-and-environmental-science/applied-geoscience-petroleum-and-mining-geoscience/multiphase-flow-permeable-media-pore-scale-perspective?format=HB&isbn=9781107093461
Hi. Could you please explain more about ift. How ift can affect the oil recovery? What is its specific mechanism? I mean what will happen when ift decreases. I know that it will reduce the absolute value of the capillary pressure and this can result in oil recovery increase but I want to understand the way or the mechanism. The mechanism of wettability alteration is clear but ift is unclear for me. I mean what will happen to the interface between oil and water. How it will change and in which way it will increase the recovery? After ift reduction the phases will be miscible or what? ??? I can not imagine the shape of the oil droplet after ift reduction? Could you please make it clear for me. Thanks in advance.
i think you have to check the literature about it. What you are asking is deep research in physical chemistry or even organic chemistry and first of all you must know what type of oil you use, the specific molecules of oil and how the interact or even react with water and the constituents of water!

Hi, im reservoir engineering inter in a Petroleum operator in brazil, how can i buy your book? Can i get a e-book version?

did you find it? I am asking because I am looking for the same. Help would be appreciated.
