Petrobras has been developing deep water oil fields located in Campos Basin, a vanguard subsea project which faces big challenges, one of them wax deposition in production flowlines. So, since 1990, Petrobras has been studying methods to prevent and remove paraffin-wax deposits. Tests of techniques based on chemical inhibition of crystal growth, thermo-chemical cleaning (SGN), mechanical cleaning (pigging), electrical heating and thermal insulation were done and the main results obtained at CENPES (Petrobras R and D Center) started to be used in the field in 1993. This paper presents solutions and procedures which has been used to minimize oil production losses at Campos Basin -- Brazil.
