SAFE-BREAK  611  additive  is  a  concentrated  blend  of  surfactants  and  solvents  designed  to  prevent   emulsions  or  improve  compatibility  cause  by  the  interaction  of  highly  asphaltic  crude  oils  and  seawater,  low‐density  completion  brines  and  acidizing  treatments.   SAFE-BREAK  611  additive  prevents  or  eliminates  the  sludge  caused  by  the  flocculation  of  asphaltenes  and  produces  a  clean,  sharp  interface  between  the  water/oil  phases.   It  is  also  effective  in  controlling  reverse  wettability  or  oil‐wetting  effects  caused  by  strongly  cationic  surfactants.   SAFE‐BREAK  611  additive  is  soluble  in  seawater  and  low‐density  brines  such  as  2‐3%  KCl  and  3%  NH4Cl.
