We propose an experimental methodology to visualize asphaltene precipitation in the pore space of rocks and assess reduction permeability. perform core flooding experiments integrated with X-ray microtomography (micro-CT). The simultaneous injection pure heptane crude oil containing induces space. degree is controlled by measurement differential pressure across sample. After precipitation, dope...

A high content of asphaltene and wax in crude oil leads to difficulties the recovery transportation due precipitation asphaltenes deposition waxes. Comb-like polymers were found be capable inhibiting aggregation crystallization In this work, comb-like bipolymers α-olefins/ultra-long chain (C18, C22 C28) alkyl acrylate synthesized characterized by FT-IR 1H NMR spectra. The results show that, for...

The coexistence of several schools in non-equilibrium thermodynamics is a reality.At the beginning of the 21st century, the thermodynamics of systems far from. However, it turns out that many nonequilibrium phenomena can be described.An alternate evolutionary hypothesis is discussed: non-equilibrium. Literature on non-equilibrium thermodynamics and its relationship to evolutionary.The online ve...

The birth, raise, development and fortunes of a fundamental theory in thermodynamics, the axiomatic thermodynamics, a creation of Constantin Carathéodory, is thoroughly presented together with a summary of Carathéodory’s biography. Axiomatic thermodynamics is centered around some interesting properties of Pfaffian differential equations, which are here introduced and used for some well-known ca...

Deep insights into the movability of retained shale oil are great significance to oil. Rock and crude samples were collected from well J174 in Jimsar Sag, Junggar Basin. subjected different extraction followed by analysis component extracts, measurement porosity conjunction with nuclear magnetic resonance high-pressure mercury injection analysis. The results these analyses used establish an exp...
