Accomplishments for the year are presented for the following three tasks: (1) adsorption of surfactants on reservoir minerals; (2) polymer-surfactant interactions; and (3) observations of oil displacement by computed tomography. Under Task 1 the following are covered: materials and methods; adsorption of isomerically pure n-decylbenzensulfonate on reservoir minerals; role of surfactant structure on adsorption; desorption and pH effects; and effect of salinity on adsorption of dodecylsulfonate on alumina. Task 2 covers: experimental results and discussion on adsorption kinetics, adsorption isotherms and desorption, and conclusions. Task 3 includes: methods; discussion on residual oil saturation in uniform cores and stability analysis; and conclusions. 39 references, 54 figures, 12 tables.
