... non-ionic surfactants. The objective was to meet intrinsic surfactant properties, such as high cloud point (CP), low surface tension (ST), adequate contact angle (CA) and low critical micelle concentration (CMC). In addition to the essential physical-chemical properties, improvement in fluid recovery...

... in reducing the yield stresses of waxy gels have been tested in yield closed-loop laboratory deposition cell. Tests with a multi-component wax solution with polymer additions of 0.1wt% showed that the thickness of the deposit could be estimated from calculations of the height of the cloud point above the cold...

... Abstract Paraffin-waxes present in crude oils, at some thermodynamic states, exhibit the phenomenon of crystallization. The onset of wax crystallization temperature of stock tank oil at atmospheric pressure is known as the cloud point. In this paper, cloud point data are presented for several...

... of commercial additives has been selected to prepare drilling fluids with simplified compositions: potassium and sodium salts (chloride, nitrate, carbonate, and acetate), three polyglycols with Cloud Point (CP A, CP B and CP C), three soluble polyglycols (SG A, SG B, SG C), an inhibitive cationic polymer, a low...

..., mechanical (indentation) tests on cuttings aged for 12 days at 80°C have been run. In addition to organic and inorganic sodium and potassium salts, two commercial glycols (with and without Cloud Point) have been selected and analyzed. All the experiments have been carried out at alkaline pH. It is shown...
