Abstract
The limited supply and increasing cost of petroleum-based surfactants for chemical enhanced oil recovery have led Texaco to study renewable resources as sources of improved oil recovery (lOR) surfactants. The starting material of choice is lignin, the second most abundant organic chemical on earth. Lignins are produced in large quantities as waste in pulp and paper mills and are very inexpensive.
