Cerogel PPG-746

The Cerogel PPG products form intermediate strength gels, with both viscoelastic properties and plugging efficiency. They can be added into the injection water for a brief periods of treatment time and will travel some distance from the wellbore and plug the very high permeability intervals (including super-K permeability zones) and even narrow fractures. The injection water that then follows the PPG treatment is forced to flow more into the lower permeability zones that have as of yet not been swept very much by the injection water. The overall result of a successful treatment is an increase in the oil production and decrease in the water rate in offset producers.

• Improves Conformance Control - Selective blocking effect – only block major thief zones and fractures. The result is more controllable than a polymer/cross-link gel system.
• High Temperature/salinity Tolerance - PPG particles are stable in high temperature and saline brine reservoirs. It can be applied in reservoir at temperatures below 120 ºC and with a broad range of salinity.
• Easy to Implement - Treatment design can be adjusted “on the fly” and can be used for both vertical and multilateral wells. Simple rigless operation process and surface injection equipment.
• Cost-effective - High chemical efficiency (< 2 lb PPG/bbl incremental oil). Only a few dollars per barrel incremental oil.
