ENEREX offers different types of petrophysical measurements on samples, from drilling cores or outcrops. Sampling campaigns and sample preparation can be carried out by us, according to your requests. The added value of ENEREX is also in the interpretation of the results and their integration into geological models for your exploration needs.
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.
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
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.
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.
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.
Measures the matrix permeability, key property to characterize the fluid transfers. These measures are made at room temperature and under 20 bars confining pressure.
