Development of Enhanced Nanocomposite Preformed Particle Gels for Conformance Control in High-Temperature and High-Salinity Oil Reservoirs
2014
Conventional preformed particle gels (PPGs) of homo-polyacrylamide have been improved by incorporating an optimized ratio of functional groups, AMPS and NVP. The improved PPG shows acceptable viscoelastic properties, thermal and ionic strength stability when they are exposed and aged under high-temperature (130 °C) and high-salinity (225 000 p.p.m. of TDS) conditions. According to the experimental results obtained, these improved PPG can be used for water control purposes under harsh reservoir conditions.
