Paper presented at the SPE Middle East Oil and Gas Show and Conference, March 18–21, 2019
Paper Number: SPE-194706-MS
... ABSTRACT Asphaltene deposition can cause production reduction in oil fields and can create problems in surface/subsurface equipment. The three main factors which affect asphaltene stability in a crude oil are the changes in pressure, temperature and composition. Composition changes occur...

... increase in oil recovery. In this paper, advanced sum frequency generation (SFG) spectroscopy is utilized, for the first time, to characterize the chemical structures of molecules at the brine/crude oil interfaces. The change in the chemical structure is perceived with time at a broad wavenumber range...

A capillary tube filled with solutions, which had not been pre-equilibrated with oil, and a fresh drop of crude oil, was spun at 5,000 rpm. Spinning continued until observing an equilibrium condition, as indicated...
