The Ultra-perm 500™ is a digital, steady state gas permeameter system for plug size
and full diameter core samples. The Ultra-perm-500™ utilizes precision mass flow
meters and a differential pressure transducer array to bring steady-state gas flow
measurements to a new level of sophistication.
Combining automated data acquisition
with a real time graphical interface the accuracy and PC controlled measurement
cycles the precision and range of measurements is enhanced. Visual color changes
in the pressure and flow rate displays alert the operator to data being collection
in either the bottom 5% or the top 5% of the relevant devices operating range.
A real time plot of unitized pressure drop along the sample versus unitized flow rate
allows the operator to determine if the laminar flow regime required for the application
of Darcy’s Law is met. Criteria derived from Section 6.8 of the American Petroleum
Institute’s "Recommended Practice for Core Analysis" are used to determine the transition
from laminar flow to turbulent flow within the core sample. A traveling meniscus
option allows measurements to be accurately made down to 0.001 md further enhancing
the range of the system.
Data files are stored in HTML format allowing seamless importation into databases
and spreadsheets such as Access and Excel. The UltraPerm-500 is compatible with
both ambient and reservoir stress determinations using existing core holders.
Permeability Measurement Range: 0.001md to 40,000md.
