CYDAREX

• created with IFP, now 100 R. Lenormand
• software CYDAR
• design and interpretation of SCAL experiments
• measurements on drill cuttings
• porosity and permeability
• consulting SCAL

CYDAR

• Design and interpretation of laboratory
  experiments
• can be used by technicians
• Windows environment
• pre-programmed experiments
• use of more recent models for interpretation
  (SCA publications)
• customized reporting

CYDAR Modules

• MERCURY
• PERM monophasic permeability
• KrUSS (Kr unsteady-state)
• SteadyState (Kr steady-state)
• CENTRI (Pc et Kr by centrifugation)
• TPF (Two-Phase Flow)

Modules can be run separately
