New
England Research AutoLab 500 Laboratory System
The AutoLab 500 is a
compact, manually operated system for measurements of compressional and shear wave
velocities, formation factor (electrical resistivity), and compressibility on rock core
at in situ overburden and pore pressures.
Compressional and shear wave
velocities are measured with NER's PS2 ultrasonic transducer
assembly. These assemblies easily measure one compressional and two shear
wave velocities at confining pressures to 10,000 psi and pore pressures to 7,500
psi. Rugged core holder assemblies accommodate core diameters to 1.50
inches.
Key
features include:
PS2 transducers for compressional and shear wave
velocities
Formation factor (electrical resistivity)
Strain measurements with strain gages
Electronics console for signal conditioners, compressional and shear wave
selection, and complex resistivity.
AutoLab
software which:
Acquires data from each transducer
Acquires and processes compressional and shear waveforms
Acquires and processes sample resistivity
Displays and reports results in a turnkey system.
Enjoy the features of the AutoLab system in a portable
apparatus. AutoLab 500 utilizes the same high quality core holders used in all of
NER's systems. Take it into the field to measure rock cores at the well site.
Calibrate sonic logs and develop empirical relationships between elastic wave velocity,
porosity, and permeability. Determine elastic anisotropy to constrain seismic
models. These are a few of the readily apparent applications. AutoLab software
acquires the data, rapidly processes the results, and generates a comprehensive, easy to
interpret data report.
The high pressure system consists
of a pressure vessel, a hand pump for confining pressure and an air driven pore pressure
intensifier. Coreholders for velocity, permeability, and resistivity are mounted on
clover leaf closures which insert in the pressure vessel and lock with a
120 degree rotation. This design is convenient and efficient for routine measurements at normal
reservoir pressures.
