Abstract:

Dataset contains measurements of the interfacial tension (IFT) between Louisiana Sweet Crude oil (LSC) and artificial seawater. Measurements included are averages from three data points. Related density data can be found in GRIIDC datasets R4.x267.000:0011 and R4.x267.000:0012.

Purpose:

The experiments have been done to get information about the interaction of oil and seawater as function of pressure and temperature. The interfacial tension is an important physical parameter to know as it is required for several theoretical determinations, simulations and the comparison of experimental data, e.g. rise velocities, with theory.

Data Parameters and Units:

Measurement of interfacial tension between LSC and artificial seawater (mN m^-1), Temperature (4 °C, 20 °C, 35 °C), Pressure (0 to 15 MPa), Time (decimal minutes), Standard deviation (sdv)

Methods:

Interfacial tension measured via pendant drop method. Three separate test runs were evaluated at each temperature and pressure combinations, i.e. 3 drops under each conditions were followed for at least 90 minutes. Interfacial tension was measured at eleven temperature and pressure combinations. Artificial seawater was prepared via the recipe of D.R. Kester et. al. 1967.
