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 150-392℉ (65-200℃)
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℃ *24 hrs.
API fluid loss:
≤50 mL (160℃)
Further information about field jobs is described in documented “Case History of EZCem Technology”.
Typical thickening time curves of EZCem slurries are shown in the following Figures.
Precautions and HSE Considerations
High
temperature retarder (KCM007L), dispersant (KCM012S and KCM012L), and fluid
loss control agent (KCM008S and KCM008L) in EZCem systemd play the most
important role in EZCem cementing job design. KCM003 is generally used to
eliminate gas trapped in EZCem slurries.
The laboratory procedures, quality assurance
program and guidelines for field mixing and handling of EZCem systems are
described in EZCem fluid manual.
