Tested here, made here

An in-house Class II Lab and certified management systems keep specifications consistent from development to shipment.

R&D & QUALITYClass II Lab

In-house testing center

Our Class II testing center runs the full verification loop for oilfield chemicals — from raw-material checks to finished-product release.

  • Rheology and viscoelastic behavior of fluid systems
  • Fluid-loss and filtration performance under temperature and pressure
  • Density, pH and chemical stability profiles
  • Compatibility testing against customer base fluids

Instrument capability

The lab is equipped for the standard oilfield-chemical test programs, covering drilling, cementing and production chemistries.

  • High-temperature, high-pressure filtration testing
  • Rotational viscometry for full rheological profiles
  • Aging and thermal-stability evaluation
  • Slurry consistency and strength-development testing

Certified management systems

Quality, environmental and occupational-health systems are certified and audited — the framework behind batch-to-batch consistency.

  • ISO 9001 quality management
  • ISO 14001 environmental management
  • ISO 45001 occupational health & safety
