Surfactant development for enhanced oil recovery. Seventh quarterly report, April 1--June 30, 1995
The overall objective of the project is to develop surfactant system(s) that will enhance projects on tertiary oil recovery. Such surfactant systems will be expected to be stable at high temperatures and exhibit high salinity tolerance. The authors have shown in previous reports that double-tailed surfactants show very good promise as well as remarkable potential for effective tertiary oil recovery. For this reason they have continued to devote research activities on this class of surfactants. In this report two additional double-tailed surfactants were synthesized and their critical micelle concentration (CMC) determined. These surfactants are sodium dihexadecyl phosphate (SDDP) and calcium ditetradecyl sulfonate CaDTDS. These are all anionic surfactants with different head groups. The observed critical micelle concentration for these surfactants are 0.78 {times} 10{sup {minus}5} M and 0.81 {times} 10{sup {minus}5} M, respectively. These CMC values were obtained using conductometric and surface tensiometric methods.
