Laboratory Investigation of Static Bulk-Foam Tests in the Absence and Presence of Crude Oil

This is the authors' abstract. We don't add key points for this paper.

Bulk foam-tests have been conducted at ambient conditions in the absence and presence of oil using Doumeen and Ethomeen surfactants and Nitrogen as the primary mixing gas. The effects of brine salinity and surfactant concentration on foam generation and stability are investigated. In another set of experiments, both brine salinity and surfactant concentration are fixed and the effect of type of mixing gas (N2, CO2 and air) on foam generation and stability are studied. Foam height after mixing with gas is recorded and it represents foam generation. The time for foam to break to half of its original height is recorded to represent foam stability. Comparison of results for experiments in absence/presence of oil reveals that oil is detrimental to foam generation and stability in this studies.
