Most of the recent studies conducted similar experiments at ambient conditions. However, one of the limitations of different previously laboratory studies is the lack of measurements with gas as they were done using air or crude oil. The major component in shale gas is methane plus some lighter hydrocarbon. In this chapter we will investigate the surfactant solution behavior with some light hydrocarbons such as n-Heptane to better mimic reservoir hydrocarbon behavior. All necessary laboratory experiments had been conducted plus phase behavior for the selected surfactants. Anionic surfactants gave excellent aqueous stability results however; the impact of the salinity was observed carefully. An optimized formulation was achieved that resulted in type III microemulsion. © 2023 The Authors. date: 2023 publisher: IOS Press official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85172818608&doi=10.3233%2fAERD230025&partnerID=40&md5=77e6de9a340345cb0a5f47422d86ebc7 id_number: 10.3233/AERD230025 full_text_status: none publication: Unconventional Methods for Geoscience, Shale Gas and Petroleum in the 21st Century pagerange: 282-296 refereed: TRUE isbn: 9781643684192; 9781643684185 citation: Ayoub, M.A. and Mohyeldinn, M.E. and Babiker, N.A. and Negash, A.B.M.
