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
3
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

main features
- Data Input
- ASCII files, clipboard from Excel
- opening of experimental files
- Data fitting and smoothing (Splines)
- Export graph and tables
- Reporting

1 - MERCURY
- direct opening of the ASCII file generated by the
experimental apparatus - data smoothing by spline functions
- first injection, withdrawal and second injection
- calculation of 3 types of pore size distributions
- permeability estimation
- reservoir Capillary Pressure
