Nano-Perm™

Innovation for Accurate Evaluation

The challenges faced by engineers and geoscientists evaluating unconventional reservoirs of the 21st century clearly demonstrate the necessity for data of the highest quality. It was a response to this client need that drove Core Laboratories to develop the Nano-PermTM. Every aspect of the instrumentation for the Nano-Perm was designed to provide the highest level of data confidence for evaluating sub-microdarcy permeability.

• Precisely and accurately determines ultra-low permeability of potential natural gas and oil-shale reservoir
• Applicable in liquid-rich, oil-shale reservoirs in the Bakken, Eagle Ford, and Niobrara formations, among others
• Accurate over a wide permeability range
• Steady-state, inert-gas flow dynamics to generate data sets from which nanoscale permeability can be accurately calculated
• Measured and calculated data sets are superior to permeability estimates from digitally imaged nanometer cubes
• Allows evaluation of stress sensitivity (up to 10,000 psi net confining stress)

This state of the art, steady-state device provides the flexibility to vary the confining stress from 1000 psig to 10,000 psig. Precise control of the flow rate makes it possible to build a robust data set which allows for a Klinkenberg corrected permeability
