Improve sweeping efficiency from injection wells
Halliburton water swelling polymer is a “bullhead” type treatment designed for shut-off of fractured or highly vugular zones in injection wells. CrystalSeal Service treats the injection wells rather than producing wells, providing a farther-reaching effect with substantially no risk of damage to the producers.
Easy deployment for immediate impact
CrystalSeal offers the following advantages:
- Improves the sweep efficiency of injection systems, e.g., water flooding and water-alternating-gas (WAG) flooding
- Takes effect in only a matter of hours; does not require specialized mixing equipment, and can be added on the fly
- Resists carbon dioxide (CO2) contamination, acid contamination, and/or hydrogen sulfide (H2S) environments
- Withstands the influx of water and helps prevent dilution of cement or other remediation products
- Contains no heavy metal; is nontoxic and environmentally acceptable
- Can be removed with oxidizers or bleaching compounds
