Surfactant for self-diverting acid

ADDITIVES FOR ACIDIZING FLUID

SURFACTANT FOR SELF-DIVERTING ACID

DESCRIPTION:

The product is a zwitterionic surfactant which is added into the acid to prepare self-diverting acidizing fluids.

FEATURES:

- Excellent anti-filtration and retardation properties.
- Low frictional resistance of the system, high pump-in flow rate and low cleaning pressure.
- Low residual, will not cause secondary damage to the formation.
- Can tolerate extreme shear and high temperature
- Can be used in acidizing operation of Sulphur-bearing wells.
- With its unique rheological properties, it enables the acid to enter accurately into the target.

APPLICATION:

Used as a self-diverting additive in the self-diverting acidizing fluids of the large flow SRV(stimulated reservoir volume) in unconventional reservoir. The fluid’s viscosity increases promptly the moment the acid reacting with rock while self-diverting acidizing fluid is injected into subterranean formation, that makes the subsequent acidizing liquid change its direction into the lower
resistance path expand the acidizing area.

RECOMMENDED DOSAGE

4-6% Volumetric fracturing restriction
