Following an earlier paper (SPE 37274, 1997), we have continued to investigate the thermal stability of scale inhibitors for application in high presure/high temeprature *HP/HT) reserviors. HP/HT reservoirs are currently under develpment in the North Sea and are characterised by high salinity brines (TDS>300,000 ppm) high temepratures (T>175 deg) and high pressures (12,000 - 15,000 psi, approx 800 - 1050 bar). At present produced brines are treated with scale inhibitors to prevent mineral scale deposition within tubulars and topside equipment. However, the conventional polymer and phosphonate scale inhibitors currently being used may not be apropriate for application in the harsh HP/HT reservoirs.
