OSTI ID:379630
In this paper, results are presented from a series of scale inhibitor core flood experiments using oil reconditioned reservoir cores from four North Sea fields. Phosphonate, poly phosphino carboxylic acid, poly acrylic acid and sulphonated acrylic acid scale inhibitors were used in order to evaluate their performance prior to field squeeze application. Different methods of application were considered including both (i) adsorption/desorption and (ii) precipitation/redissolution type squeeze treatments. The return profiles for the different types of applications and the different chemistries are compared as are the observed formation damage effects. The advantages and disadvantages are outline for these two mechanism in terms of the extending squeeze lifetime vs potential for formation damage. It is intend that this paper contributes to the development of better designed and safer field applications of both adsorption and precipitation scale inhibitor squeeze treatments in the light of individual reservoir petrography and petrophysical properties.
