As oil and gas becomes more difficult to find and wells are drilled deeper the well bottom hole temperature increases. The temperatures of deep wells can be as high as 230°C. There are a limited number of oil soluble corrosion inhibitors that work well in such systems. In this paper we report the development of a new water based corrosion inhibitor that works at high temperature and can be injected using a capillary string. A new water soluble corrosion inhibitor has many advantages such as greater partitioning in the water phase, higher flash point and higher reportable quantities (RQ) if a spill occurs than the oil soluble counterparts. In this paper the laboratory studies on new high temperature water soluble corrosion inhibitor are reported. The performance of this corrosion inhibitor in a field trial is also reported. Wherever possible the water soluble corrosion inhibitor will be compared with a standard high temperature oil soluble corrosion inhibitor.

Keywords: High temperature corrosion inhibitor, high temperature and pressure, HT/HP
