Typical Properties and Field Applications

PETCem 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 150-375℉ (65-190℃)
Density:	8.0 ppg to 21.5 ppg (0.95 –2.60 g/cm³)
Mix-water:	Fresh water, brines (up to 18%)
API fluid loss:	Less than 50 mL
Rheology:	PV: 50-200 cP, YP: 5-30 lbs/100ft²

Further information about field jobs is described in documented “Case History of PETCem Technology”.

Precautions and HSE Considerations

Coarse (KCM019, KCM020, KCM021, KCM030, KCM031), medium (cement, KCM032) and fine particles (KCM029, KCM033) are generally used in PETCem systems to design cement slurries at low or high densities. They are generally inert particulates which is compatible with other additives such as fluid loss agent, retarder, dispersant in PETCem systems.

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