Abstract:

Dataset contains measurements of the interfacial tension (IFT) of methane-saturated Louisiana Sweet Crude oil (LSC) and artificial seawater using the pendant drop method at 20 °C. Related density data can be found in GRIIDC dataset R4.x267.000:0090.

Purpose:

The experiments have been done to get information about the interaction of methane-saturated oil and seawater as function of pressure. 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:

Temperature (°C) Pressure (MPa) Interfacial tension (mN m^-1) Time (decimal minutes) Density (g/mL)

Methods:

Pendant drop method used to measure interfacial tension. Saturation method: 40 mL of LSC are placed inside an accumulator vessel of approx. 70 mL. This vessel is pressurized with CH4 up to the designated pressure. The vessel is shaken to obtain equilibrium. Artificial seawater was prepared via the recipe of D.R. Kester et. al. 1967.
