Materials Characterization Solutions to Determine Unconventional Gas Reservoir Potential

Shales are complex reservoirs and present significant challenges to petrophysical characterization and physical core analysis. Key reservoir parameters for shale deposits include: thermal maturity, reservoir thickness, total organic carbon (TOC) content, adsorbed gas fraction, free gas fraction within the pores and fractures, and transport properties.
Thermal maturity and reservoir thickness are routinely measured. The remaining four parameters require a creative approach that can utilize a number of petrophysical rock core measurement techniques.

Micromeritics provides key analytical tools for evaluating rock cores and shale reservoir potential.

  • Reservoir performance evaluation
  • Gas storage capacity of shale and kerogen
  • Correlation between geological conditions and physical properties
  • Organic and non-organic matrix porosities and pore distributions

Micromeritics also provides computational and modeling tools for modeling and predicting shale reservoir potential.

3Flex Physisorption

High Resolution, High-throughput Physisorption and Chemisorption Instrument

Recognized as the most advanced instrument in the field for material surface characterization. The 3Flex has become a crucial tool for providing high resolution adsorption, desorption, isotherms to advance and validate fundamental understanding into development of methodologies and process improvements.

AccuPyc II 1345

Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This technique is non-destructive as it uses the gas displacement method to measure volume. Inert gases, such as helium or nitrogen, are used as the displacement medium. Density calculations using the gas displacement method are much more accurate and reproducible than the traditional Archimedes water displacement method.

AutoPore V – Mercury Intrusion Porosimetry

Class Leading, Proven Performance Establishing a New Benchmark for Operational Safety

The mercury porosimetry analysis technique is based on the intrusion of mercury into a porous structure under stringently controlled pressures. Besides offering speed, accuracy, and a wide measurement range, mercury porosimetry permits you to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter and sample densities (bulk and skeletal).

HPVA II

The HPVA II Series of adsorption analyzers from Particulate Systems uses the static volumetric method to obtain high-pressure adsorption and desorption isotherms utilizing gases such as hydrogen, methane, and carbon dioxide. The volumetric technique consists of introducing [dosing] a known amount of gas [adsorptive] into the chamber containing the sample to be analyzed.

When the sample reaches equilibrium with the adsorbate gas, the final equilibrium pressure is recorded. These data are then used to calculate the quantity of gas adsorbed by the sample.
