Our laboratory, located in Argenteuil (France) consists of a team of engineers and experienced geologists. In order to remain at the forefront of technology and to continually evolve our service, we follow new innovations by actively participating in University research projects.


We operate a wide range of equipment and can offer a broad spectrum of analytical procedures; we are constantly adapting our methodologies in order to offer our clients the most reliable results possible.


We are experienced and we have the knowledge of oil & gas, mining and carrying issues. Our experience is specifically recognized in the industrial world for quantifying the reactive silica by petrological analysis, for analyzing plugs and cores (petrography and petrophysics), and for detecting and characterizing asbestos in natural materials.


Our service is tailored to the client’s requirements and we offer a full range of analyses, from simple description of cuttings and cores on site, through the petrophysical analysis or petrologic description, up to interpretation and integration of results into environmental and geological studies.


Oil & Gas sector (New lab GEOREX-STC at Boussens, beginning 2015)

Our laboratory performs all types of analysis related to the characterization of petroleum systems (reservoirs, rock type, water, seal,...).

  • Permeability measurements using the "unsteady - state" method (Kair,  Klinkenberg, alpha and beta factors)
  • Phi - K on cuttings
  • Cell for performing triaxial tests on plugs with confining stress (failure criterion, elastic modulus, etc.)


Petrologic characterization of reservoirs

  • Production of thin sections (blue porosity, Alizarin staining, evaporites,...)
  • Determination of microfacies
  • Diagenetic studies, description and quantification of different porosity types
