Sample measurement services

P and S-wave propagation velocity

To calibrate seismic prospection, well logs, or estimate the elastic properties. Combined with the other measurements, the microfractures and weathering of the material can be assessed. With different direction measurements, it is also possible to quantify the formation anisotropy.

Thermal Conductivity et Diffusivity

The knowledge of the thermal properties of the rocks is necessary to simulate the conductive heat transfer in the reservoirs. Combined with density data, the heat capacity can be calculated for a complete characterization of the thermic. These measures are made at room temperature, with dry or saturated samples.

Mercury porosimetry

Characterize the pore throat diameter (= pore size proxy) distribution, from 400 to 0.005 μm diameter. Give also indirect information about the pore network morphology

On plugs

Triple weighing porosity

For estimation of the connected porosity, a key property for the rock matrice characterization for fluid storage in the reservoir.

Nuclear Magnetic Resonance

Estimates the pore size distribution and allows the calibration of RMN well-logs.

Electric Resistivity

Allows to estimate the electric resistivity of the formation and calibrate the interpretation of well logs resistivity. These measures are made on saturated samples at 4 different salinities.

Skeletal density

Estimates the grain density of the rocks. This property can be used to calibrating the interpretation of gravity maps or density well logs. On powdered samples, it allow also to assess the non-connected porosity.

Nitrogen Permeability 

Measures the matrix permeability, key property to characterize the fluid transfers. These measures are made at room temperature and under 20 bars confining pressure.


According to your wishes, these measures can be compared with our properties database for comparison to reservoir analogs and a complete study of your targeted prospect.

Structural Geology services

Lineament analysis

Constrains the structural background of the prospected area, with satellite data or aerial photographs on the prospected area or outcropping analogs. These data also help to plan the geophysical prospection and to classify the structural features important for fluid flows at different scales.

Field study

Characterize the geologic formation at the reservoir scale. A fracture analysis can be conducted to include the fracture network in fluid flow modeling. This study can be combined with an accurate rock sampling for matrix properties measurement.


Geophysics services

Magnetic surveys

We offer ground, drone, and airborne magnetic surveys to provide a vast range of resolution, from 10 cm to hundreds of meters above the ground, in order to adapt to any kind of project.

Interpretation of magnetic data

We offer processing and interpretation of magnetic data measured by us or by other companies. We adapt to your projects by proposing different kinds of results:  map of the magnetic anomaly, potential field transforms, direct modeling, inverse problem solving for parameters evaluation (such as depth or magnetization).


Planning, quality assurance, quality control

We offer support in the planning of the magnetic surveys of your project according to your objectives. We can also provide quality assurance of your own surveys or quality control from third part companies.


Seismic Interpretation

Interpretation of 2D seismic profiles for stratigraphic and structural correlation until the creation of a 3D geologic meshed model.
