Typical Properties and Field Applications
FCS technology was commercialized in 2011 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 60‑375°F (15‑191°C) |
|
Density: |
8.3 ppg to 23.3 ppg (1.00‑2.80 g/cm3) |
|
Mix-water: |
Fresh water |
|
Compressive strength: |
20‑30 MPa/200°C for 7 days |
|
API fluid loss: |
≤50 mL |
|
Treatment wells: |
Steam injectors, gas storage wells, geothermal wells, unconventional multi‑stage fracturing wells |
Precautions and HSE Considerations
FCS systems include three major additives which are flexible additive (KCM024) and expanding agents (KCM025UH/KCM025HC/KCM025LT). Other additives such as fluid loss agent, retarder, dispersant are generally used for controllable rheological, fluid loss, thickening time and stability of FCS cement slurries. Laboratory tests are required to confirm the compatibility between FCS additives and other additives to be used in the slurry.
The laboratory procedures, quality assurance program and guidelines for field mixing and handling of FCS systems are described in FCS fluid manual.
