Foam booster when blended with surfactant could improve the foam stability. However, the influence of foam booster on the conventional foam stability and foamability at elevated temperature and presence of inorganic electrolytes is not yet explicit due to limited studies in this area. The objective of the present work was to evaluate the influence of a foam booster on aqueous solution stability, foamability and foam stability when blended with surfactant at different ratios at an elevated temperature in the presence of brine composed of monovalent and divalent ions. Three different surfactants AOS C14�16 (alpha-olefin sulfonate), SDS (sodium dodecyl sulfate) and a locally manufactured surfactant �Surf X� were chosen as base surfactants. An amphoteric surfactant lauryl betaine was chosen as a foam booster in this study. The aqueous solution stability was visually evaluated, whereas the bulk foam experiments were conducted in a commercial foam analyzer apparatus. It was found that not all solutions were stable when lauryl betaine was blended. Lauryl betaine did not improve the foam generation time. The foam stability was improved; however, not all solutions were able to generate stable foam. �Surf X� was able to generate more stable foam as compared to AOS and when blended with lauryl betaine it also required less amount of lauryl betaine to generate stable foam. © 2019, The Author(s). date: 2019 publisher: Springer Verlag official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85075107164&doi=10.1007%2fs13202-019-0652-7&partnerID=40&md5=0f0d1dd67a57591b8cc7c088b4a8774b id_number: 10.1007/s13202-019-0652-7 full_text_status: none publication: Journal of Petroleum Exploration and Production Technology volume: 9 number: 4 pagerange: 2659-2665 refereed: TRUE issn: 21900558 citation: Syed, A.H. and Idris, A.K. and Mohshim, D.F. and Yekeen, N. and Buriro, M.A. (2019) Influence of lauryl betaine on aqueous solution stability, foamability and foam stability.
