EZCem ® - Mid-to-high Temperature Cementing Technology

Typical Properties and Field Applications

EZCem technology was commercialized in 2009 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 150‑375°F (65‑191°C)
Density:
 12.0 ppg to 20.0 ppg (1.45‑2.45 g/cm3)
Mix-water:
 Fresh water, seawater and brines
Compressive strength:
 45 MPa/175°C *24 hrs.
API fluid loss:
 ≤50 mL (160°C)
Further information about field jobs is described in documented “Case History of EZCem Technology”.

Precautions and HSE Considerations

High temperature retarder (KCM007L), dispersant (KCM002S, KCM012S), and fluid loss control agent (KCM008S) in EZCem systems play the most important role in EZCem cementing job design. KCM003 is generally used to eliminate gas trapped in EZCem slurries, but KCM043 should be used for higher temperature applications.

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