Comparative analysis in mature fields through water exclusion in copano 41 and 45 wells of the Macuspana-Muspac asset

This non-experimental study assesses the effectiveness of Conformance Sealant Technologies, specifically the MOC-ONE and SOS systems, in wells Copanó 41 and 45 of the Macuspana-Muspac Asset in southeastern Mexico. The methodology involved injecting a micro-fine oil-based cement slurry combined with NO₂ gas to seal water-producing zones. Results showed a substantial reduction in water cut, decreasing from 80% to 48%, which led to increased oil production and enhanced operational efficiency. The MOC-ONE system demonstrated high chemical resistance and adaptability to pumping conditions, while the SOS system allowed continuous production without relying on motor-compressors. Successful implementation of these technologies in the challenging environment of this mature field underscores their potential to optimize hydrocarbon recovery and control water production in similar reservoirs. These findings highlight not only technical effectiveness but also the potential economic benefits, providing a viable strategy for improving profitability in mature oil fields with complex operational conditions.
