Product Introduction：

Flow off technology not only meets the requirements of cementing construction design in terms of rheology, water loss, thickening time, strength, free water, etc., but also has excellent water loss control, thin and dense filter cake, and right angle thickening characteristics, making the system have good anti gas channeling performance. The synergistic use of liquid anti gas channeling agents, preservatives, retarders, and stabilizers makes the Flow off system a truly multifunctional anti channeling oil and gas well cementing technology.

Advantages:

Preventing oil, gas, and water leakage, environmental protection, and corrosion prevention

Simple construction operation, low risk, and good quality of consolidation

Typical performance and application conditions:

Flow off technology was successfully commercialized in 2010 and has been applied in multiple oil and gas fields worldwide. Practice has proven that this technology is effective when used under the following conditions:

Operating temperature: Static temperature 150-302 ° F (65-150 ° C)

Usage density: 10.5 ppg to 20.0 ppg (1.30-2.45 g/cm3)

Slurry water: freshwater, saltwater (concentration up to 18%)

Compressive strength: ≥ 15 MPa/24 hours

API dehydration: 15-30 mL

The typical anti gas channeling and anti-corrosion performance of Flow off cement slurry system is shown in the following figure.
