The BenchLab, available in the 7000 benchtop model and the 7000 EX floor model, is designed to measure petrophysical rock properties at reservoir pressures in a compact modular setup.
Properties measured include low permeability, ultrasonic velocities, and electrical resistivity at confining pressures up to 10,000 psi (70 MPa) with gas or liquid pore fluids.
The following options can be supported either as standalone or in any combination:
Hassler Vessel and Pycnometry Cell (gas pore fluid only):
Hydrostatic Vessel with gas or liquid pore fluids:
• Low Permeability
• Ultrasonic Velocities
• Temperature to 120° C

Core Holder and Pressurization System
Depending on the required measurement capabilities, a Hassler type core holder and a traditional hydrostatic pressure vessel configuration is used. In both cases, samples of up to 1.5 inches in diameter and 4 inches in length can be measured and taken to confining pressures up to 10,000 psi. Different end-caps are designed for each application. Pressure control and data acquisition functions are all computer controlled for automated testing.
Data Acquisition and Processing
The BenchLab series uses NER’s latest Autolab 6 software, which can operate in both Windows and Linux environments. NER’s in-house workflows for data reduction and reporting—for example, for low permeability and ultrasonic velocities—are available by default. Autolab 6 also allows scripting for unsupervised testing sequences and the use of virtual channels for extended feedback capabilities.
The BenchLab is an integrated rock properties test platform. By combining multiple property measurement modules with variable confining stress, rich data sets can be generated allowing fast cross-property analysis for direct assessment, rock typing, or modeling purposes.
For many rocks, permeability and ultrasonic velocity measurements can be performed during the same test without changing end-caps or reducing stress. This allows for rapid generation of data to build relationships between dynamic mechanical properties and permeability.
