Paper presented at the Offshore Technology Conference Asia, November 2–August 19, 2020
Paper Number: OTC-30040-MS
... The purpose of this study was to investigate the maximum amphoteric surfactant adsorption by studying parameters like rock type, salinity, alkali type, alkali concentration and surfactant concentration and to evaluate optimum parameters that would provide minimum amphoteric surfactant adsorption...

Paper presented at the SPE Improved Oil Recovery Conference, August 31–September 4, 2020
Paper Number: SPE-200315-MS
... enhance the stability of CO 2 -foam. This work investigates an amphoteric surfactant, which is commercially available and priced similarly to other commonly used EOR foamers, for its ability to stabilize CO 2 -foam. Static stability and dynamic coreflood tests were conducted at high pressure and high...

Paper presented at the SPE Saudi Arabia Section Technical Symposium and Exhibition, May 19–22, 2013
Paper Number: SPE-168104-MS
... Abstract Amphoteric surfactants are known for their tolerance to salinity and temperature and are considered as likely candidates for enhanced oil recovery (EOR) application in harsh reservoir environments. This study looked into the phase behavior properties of an amphoteric surfactant, OCT...

Paper presented at the SPE EOR Conference at Oil and Gas West Asia, April 16–18, 2012
Paper Number: SPE-155676-MS
... the use of amphoteric surfactant for enhanced oil recovery and used Arabian medium crude oil in his study. The surfactant was tested at salinity of 200,000 ppm of totaled dissolved salts with cation ratio of Na + : Ca 2+ :Mg 2+ = 10:2:1. Polymers are added to viscosify the displacing fluid to improve...

Paper Number: SPE-153988-MS
... the process economically unfeasible. This paper presents, in detail, 10 runs of core flooding tests on dynamic adsorption and desorption of an amphoteric surfactant (OCT-1) onto permeable carbonate rocks, which were conducted in natural carbonate core plugs at reservoir temperature of 100°C and pore pressure...
