Abstract
During meeting for planning operations for scale removal and scale inhibitor squeeze treatment in wells, the possibility of the manifold being partially incrusted with scale raised considering the more critical mixture of water produced. The proposed solution is a method of treatment for removing scale from a manifold. Said method uses the geothermal heating of the exploration reservoir to heat a chemical removal solution (). Heating is required to ensure the temperature is in a range that is also suitable for conducting the removal reaction, since the distance that the solution travels to the manifold () e the low temperature of the underwater environment make the reaction occur inefficiently, as in the case of pre-salt.
