We describe a protocol for preparing very stable air-in-oil foams starting with a one-phase oil solution of a fatty acid (myristic acid) in high oleic sunflower oil at high temperature. Upon cooling below the solubility limit, a two-phase mixture consisting of fatty acid crystals (length around 50 μm) dispersed in an oil solution at its solubility is formed which, after whipping, coat air bubbl...

Abstract Tight oil accumulates in impermeable reservoir rocks, often shale or tight sandstones. The flow behaviour of unconventional reservoirs is described by peculiar complexities such as the typical low permeability to viscosity ratio and dissolution some gases phase. Reservoir simulations that consider these negligible stand potential poorly characterizing dynamics. adoption similarity tran...

The answer to this question lies in knowing the moral standing of Phase IV studies and whether we ought to conduct them. And to know this, in part, we need to compare them to studies in Phases I, II, and III and then determine where Phase IV studies stand in relation to Phase I–III studies scientifically and commercially.

We present a hyperbolic-elliptic model problem related to the equations of two-phase fluid flow. The model problem is solved numerically, and properties of its solution are presented. The model equation is wellposed when linearized around a constant state, but there is a strong focusing effect, and very large solutions exists at certain times. We prove that the model problem has a smooth soluti...

This study explores how Norway, as a latecomer to oil production, was able to develop both effective oil companies and an internationally competitive oil service industry. The article focuses on two rather distinct phases: the protectionist phase, in which a strong focus on local content fostered skilled Norwegian oil companies as well as a national oil service industry, and the phase of libera...
