CYDAREX is a spin-off company of the French Institute of Petroleum (now IFPEN) and was created in 2005 by Roland Lenormand. CYDAREX specializes in the domain of core and cuttings analysis, and provides consulting and training services, commercializes the SCAL devices DarcyPress™ and DarcyLog™, and develops the software CYDAR™.
Consulting & Training
With more than 40 years of experience, Roland Lenormand, PhD, provides consulting and training services in design, interpretation, supervision, and audit in Special Core Analysis (SCAL).
Measurements on small rock samples: DarcyPress™ & DarcyLog™
Measurements on cuttings and small rock samples can improve reservoir characterization when cores are not available.
DarcyPress™ allows measurements of gas permeability under confining pressure on small rock samples (5-10 mm), with permeabilities ranging from 0.1 nanoDarcy (10-22 m2) to 10 Darcy. Giving access to very low permeabilities, DarcyPress™ is ideal for measurements on shales.
Developed in collaboration with the French Institute of Petroleum, DarcyLog™ allows measurements of permeability on drill cuttings, with sample size ranging from 1 to 5 mm, and permeability ranging from 0.05 to 100 mDarcy.
Software for Core Analysis: CYDAR™
Developed in collaboration with core analysis specialists, the software CYDAR™ offers a powerful solution for design and interpretation of SCAL experiments. This Windows-based software is designed to be user-friendly, yet accurate and powerful. CYDAR™ covers a full range of experiment types, including:
- Mercury injection and withdrawal
- Absolute permeability measurements
- Centrifuge (Pc and Kr) and two-phase flow experiments
- Relative permeability (steady and unsteady state)
- Data acquisition
