Paper: RESULTS OF ADVANCED TECHNOLOGY UTILIZATION IN SELECTIVE WATER REDUCTION

This paper presents the results of a successful application of a new-generation polymeric selective water reduction (SWT) that reduces water production without requiring zonal isolation. The SWT can be bullheaded into open intervals without the need for isolating water zones from hydrocarbon zones. As a result of this treatment, the productive life of a well can be extended, with a gradual increase in water cut. This translates to a high potential profitability value for mature fields with a high water cut. It can increase the hydrocarbon recovery percentage in formations that otherwise would be destined for abandonment. Previous papers have discussed the laboratory development of the SWT based upon the use of a hydrophobically modified polymer. This paper will focus upon the field implementation results of this technology. Specifically, this paper will focus upon candidate selection, job design, and summary of the results of treatments performed.
