High Temperature AutoLab

Over the past ten years, there has been an increasing demand for rock properties measurements at higher temperatures and pressures. University research on crustal processes requires temperatures of 300oC at pressures in excess of 200 MPa for geothermal programs, rock-fluid interactions at mid-crustal depths, frictional properties for studies of intermediate depth earthquakes, etc. The oil and gas industry is drilling deeper wells into high temperature formations in both conventional and unconventional plays. These efforts demand high quality data on at in situ conditions over realistic stress and thermal paths.

To address these needs, NER modified the AutoLab 1500 to operate at higher temperatures and pressures. The existing system is capable of temperatures of 200oC at confining pressures of 200 MPa. Since the vessel design is coaxial and unencumbered by a large thermally conductive support frame, the logical choice was to increase the maximum operating temperature to 300oC by adding internal heaters and increasing the bore length. The system supports NER’s standard measurement options: velocity, permeability, and acoustic emissions at the maximum temperature and pressure conditions. For velocity measurements, compressional (or extensional) and torsional (shear) waves are propagated through waveguides on each end of the sample.

Key Features
