The Value of Adsorption Isotherm Data
Adsorption Isotherm data are the key measurements to evaluate the "total" storage capacity of the organic component of the matrix. Understanding the total storage capacity in unconventional reservoir formations can be the key to the proper evaluation of their economic value.


Adsorption Isotherm Data


Flexible Sample Sources
Evaluation is normally done with samples taken from conventional cores samples. We offer special equipment to handle any sample type and measurement s can be made from these sample types:

  • Whole Core Samples
  • Sidewall Core Samples
  • Cuttings

Primary Evaluation - Individual Gases
Primary adsorption evaluation is made with individual gases. We offer the measurement of a multitude of individual gases including but not limited to:

  • CO2
  • Methane
  • Ethane
  • Propane
  • Nitrogen

Blended Gas Measurements
Custom gas adsorption measurements can be made using blended gas mixtures to represent any projected reservoir gas.

Adsorption and Desorption Combination
Adsorption evaluation can also be run in combination with measured desorption curves to optimize the sorption evaluation data.


Adsorption and Desorption Combination



Composite Gas Modeling

Composite Gas Modeling
The adsorptive characteristics of mixes of gases can be modeled from the primary individual gas measurements. This modeled data set can provide a single composite for any blend of gases to better predict the storage capacity of your reservoir and gas blend.
