Flow-off ® - Multi-functional Fluid Migration Control Technology

Typical Properties and Field Applications

Flow-off technology was commercialized in 2010 successfully and has been applied in various oil and gas fields in the world. It has been proved to be effective in cementing oil or gas wells with the following conditions and properties:

Temperature:
 BHST 150‑350°F (65‑175°C)
Density:
 10.5 ppg to 20.0 ppg (1.30‑2.45 g/cm3)
Mix-water:
 Fresh water, brines (up to 18%)
Compressive strength:
 ≥15 MPa/24 hrs.
API fluid loss:
 15‑30 mL
Further information about field jobs is described in documented “Case History of Flow-off Technology”.

Precautions and HSE Considerations

Fluid migration control additive (KCM028) is environmentally friendly and antifoaming. Migration control aid (KCM027) improves slurry resistance to sour gas (H2S and CO2) corrosions. Dispersant (KCM012L) and retarder (KCM026A) are specifically selected to be compatible with KCM028 and KCM027.

The laboratory procedures, quality assurance program and guidelines for field mixing and handling of Flow-off systems are described in Flow-off fluid manual.
