Summary This paper describes the use of a formulated alkyl toluene sulfonate (ATS) as a foaming agent for improving mobility control in a mature steamdrive. Selection of ATS was based on laboratory experiments and a series of field injectivity tests. The field results show production response to both the injectivity tests and the 9 months of continuous ATS injection. Overall, ATS was found to improve steam mobility and result in incremental oil production.
