Surfactant-enhanced alkaline flooding for light oil recovery. Quarterly report, July 1--September 30, 1994

Technical Report ·
OSTI ID:10109455

The overall objective of this project is to develop a very cost-effective method for formulating a successful surfactant-enhanced alkaline flood by appropriately choosing mixed alkalis which form inexpensive buffers to obtain the desired pH (between 8.5 and 12.0) for ultimate spontaneous emulsification and ultra-low tension. In addition, the novel concept of pH gradient design to optimize flood water conditions will be tested.
