Nr. Morrow et al., PROSPECTS OF IMPROVED OIL-RECOVERY RELATED TO WETTABILITY AND BRINE COMPOSITION, Journal of petroleum science & engineering, 20(3-4), 1998, pp. 267-276
Although attention is given to the composition of the injected brine i
n a waterflood with respect to compatibility with the formation, tests
are not usually made to determine its effect on oil recovery. This st
udy shows that the wettability and laboratory waterflood recoveries of
crude oil/brine/rock (COBR) ensembles can be strongly dependent on br
ine composition and on related COBR interactions. The sensitivity of t
hese interactions to temperature and crude oil composition is also dem
onstrated. (C) 1998 Published by Elsevier Science B.V. All rights rese
