Permeameter M91 series

Low Permeability Measurement Apparatus The Grace Instrument M9190 Nanodarcy Permeameter is designed to measure the low and ultra low permeability of tight plug sized core samples from shale and other tight gas reservoirs. It uses a pulse decay procedure and high pressure nitrogen to measure permeability. Confining pressure system is included for simulating overburden pressure at reservoir condition. The M9190 Nanodarcy Permeameter can operate at a pore pressure up to 2,500 psi and confining pressure up to 10,000 psi, pulse range between 5 to 200 psi. The convection oven is used to provide a constant temperature during testing. Simple Operation and Dependable Measurement The M9190 Nano-Darcy Permeameter measure the core permeability at a set pore pressure, then propagates a differential pressure pulse through the sample, M9190 software will record upstream pressure, downstream pressure, differential pressure across the sample, and time. The recorded data can then be exported in .CSV format into a spreadsheet file. Dimensions: 60" Width x 25" Depth x 35" Height Weight: 300 lbs.
