Swelling/extraction test of Russian reservoir heavy oil by liquid carbon dioxide

Wettability Alteration of Oil- Wet and Water-Wet of Iranian Heavy Oil Reservoir by CuO Nanoparticles

The petroleum industry requires the best materials to reverse the rock wettability to water-wet state which give significantly improved oil recovery.Nanoparticles are suggested as enhanced oil recovery potential agents to decrease viscosity and alter the wettability of reservoir towards more water-wet. This study provides new insights into CuO nanoparticles effects on wett...

Stability of dense liquid carbon dioxide.

We present ab initio calculations of the phase diagram of liquid CO(2) and its melting curve over a wide range of pressure and temperature conditions, including those relevant to the Earth. Several distinct liquid phases are predicted up to 200 GPa and 10,000 K based on their structural and electronic characteristics. We provide evidence for a first-order liquid-liquid phase transition with a c...

Energy Problems : Oil and Carbon Dioxide

of talk (see introduction to the articles, above): At present, nuclear fission reactors produce a sizeable fraction of the electricity in the developed world: nearly 20% in the US. and substantially greater fractions in many western European countries and in the most developed Asian countries. However. the construction of new nuclear power plants has stopped almost everywhere. with very few ord...
