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 150-302℉ (65-150℃) |
|
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”.
Typical fluid migration control and anti-corrosion properties of Flow-off slurries are shown in the following Figures.

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.
