Forty-six producers were connected to the four treated injectors with an average water cut of 95.4% before PPG treatments. A large volume (more than 1 000 m3) of PPG suspension with concentrations of 1900-2 500 mg/L and particle sizes of 0.06-3.0 mm was injected into each well, each injection spanning approximately four months. The injection PPG suspension volumes range from 11458 to 17625 m3 per well with a total of 56269 m3 (295680 lb of dried PPG) for the four wells, which indicated the existence of super-K zones or fractures in the formation. During PPG injection, real-time data, including injection pressure, injection rate and particle sizes, were monitored to tune our treatment design and to analyze the practical status of the mature reservoir. This paper reports detailed information for the four well treatments, including well candidate selection criteria, treatment design, real-time monitoring results during PPG injection and treatment results.
