.... Thermal stability and solubility were analyzed for a number of surfactants provided by two companies. Tests were conducted using a range of simulated connate brines and seawater compositions. Critical Micelle Concentration (CMC) values were estimated using a Nuclear Magnetic Resonance (NMR) protocol...

... Abstract With the continued development of offshore production in deepwater wells, a greater understanding of scale formation and corrosion under extreme high pressure and temperature (xHPHT) is needed. In order to better predict scale formation and scale solubility, knowledge...

... Abstract Methane solubility in water is significantly lower in the presence of hydrate than in water where no hydrate is present. Experiments with hydrate present show a decrease in gas solubility with both decreasing temperature and increasing pressure when crystalline hydrate is introduced...

... Abstract Carbon dioxide (CO 2 ), which is one of the most abundant compounds on Earth, is present in rock, the oceans and the atmosphere. CO2 influences many biological and dynamic processes. Carbon dioxide is very soluble in water due to its high dipole moment. Solubility of a gas in water...
