Paper: Evaluation Of A New Scale ConverterStimulation Treatment

The majority of the workovers at the Mabee San Andres Field are for the removal of calcium sulfate scale. The currently used scale converter treatment is a five step process. This includes the application of a paraffin solvent, scale converter, acid and another scale converter followed by a larger acid treatment. A new scale converter treatment is currently being evaluated. This new method uses a xylene-scale converter emulsion as the scale converter and requires only a two step treatment. The well is first treated with the xylene-scale converter emulsion and is then stimulated with acid. The xylene-scale converter treatment has been tested in the laboratory and in the field.
