Company Profile

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 instruments DarcyLog, DarcyPress™, DarcyShale™ and DarcyCap™, 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).

We have developed a one-week hands-on training on conventional and special core analysis, based on real experiments. All equipments have been costom-designed to allow measurements with in a few hours. Equipment and know-how is available for purchase.

 

Cuttings and small rocks

Measurements on cuttings and small rock samples can improve reservoir characterization when cores are not available.

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.

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.

DarcyShale™ is an improved GRI method allowing measurements of very low permeabilities, in the nanoDarcy range.

DarcyCap™ allows fast measurements of capillary pressure, pore size distribution, and resistivity index using the porous plate method.

 

Software for Core Analysis CYDAR

Developed in collaboration with core analysis specialists, the software CYDAR™ offers a powerful solution for design and interpretation of conventional and special core analysis 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 (MICP)

► Absolute permeability measurements

► Dispersion measurements

► Centrifuge (Pc and Kr) and two-phase flow experiments

► Relative permeability (steady and unsteady state)

► Electrical Measurements

► EOR – Enhanced Oil Recovery

► Automatic reporting

► Data acquisition

CYDAR™ is now used by more than 100 companies and universities worldwide.
