Overview
The NIUMAG MesoMR Custom Series is a purpose-engineered low-field nuclear magnetic resonance (NMR) analyzer designed explicitly for laboratory-scale characterization of geological formations in carbon capture, utilization, and storage (CCUS) and carbon capture and storage (CCS) research. Operating at a stable static magnetic field of 0.3 ± 0.05 T generated by a C-shaped permanent magnet, the system employs pulsed NMR techniques—including Carr–Purcell–Meiboom–Gill (CPMG), inversion recovery (IR), and spin echo (SE)—to non-invasively probe hydrogen-bearing fluid distributions and dynamics within porous media. Unlike high-field NMR spectrometers optimized for molecular structure elucidation, the MesoMR series prioritizes robustness, thermal stability, and modularity for long-duration core-flooding experiments under controlled temperature and pressure conditions. Its open C-frame architecture enables seamless integration with external hardware modules—such as high-pressure cells (up to 70 MPa), cryogenic stages (−40 °C to +120 °C), and custom RF coils—making it suitable for simulating subsurface reservoir environments relevant to CO₂ injection, brine displacement, caprock integrity assessment, and plume migration monitoring.
Key Features
- Modular platform supporting user-defined configurations: vertical/horizontal sample loading, variable coil diameters (15–100 mm), and interchangeable gradient/shim assemblies
- Integrated temperature and pressure control interfaces compliant with ASTM D7900 and ISO 17892-6 for geomechanical core testing
- Real-time NMR signal acquisition with 16-bit ADC resolution and <100 ns timing precision for accurate T₂, T₁, and diffusion coefficient mapping
- Pre-calibrated pulse sequences for quantitative porosity, pore-size distribution (PSD), fluid saturation, movable/immobile fluid ratio, permeability estimation (via Timur-Coates or SDR models), and wettability index derivation
- Rugged industrial-grade enclosure rated IP54, enabling deployment in shared lab environments without dedicated RF-shielded rooms
Sample Compatibility & Compliance
The MesoMR Custom Series accommodates cylindrical rock cores (up to Ø100 mm × 200 mm L), unconsolidated sediments, cementitious materials, and synthetic porous media. It supports dual-phase (solid matrix + liquid/gas phase) analysis—critical for tracking CO₂–brine–rock interactions during injection and post-injection trapping mechanisms (structural, residual, solubility, and mineral trapping). All measurement protocols adhere to recognized standards including ASTM D6913 (particle-size distribution), ISO 15175 (porosity determination), and USP (analytical instrument qualification framework). Audit trails, electronic signatures, and method versioning are fully supported to meet GLP and GMP requirements per FDA 21 CFR Part 11 when configured with optional secure software licensing.
Software & Data Management
NIUMAG’s proprietary MultiQ™ NMR Analysis Suite provides end-to-end workflow automation—from sequence setup and real-time signal visualization to multi-parameter inversion (e.g., T₂–D, T₁–T₂ correlation maps) and statistical reporting. The software exports data in HDF5 and CSV formats compatible with MATLAB, Python (NumPy/Pandas), and commercial reservoir simulators (e.g., CMG, TOUGH2). Built-in calibration tools reference NIST-traceable standards (e.g., doped water phantoms, glass beads), ensuring inter-laboratory reproducibility. Remote access, role-based permissions, and encrypted database backups further enhance data governance for multi-site CCUS projects.
Applications
- Quantitative evaluation of CO₂ saturation evolution during core flooding under reservoir-relevant P/T conditions
- In-situ monitoring of methane displacement by CO₂ in coal seam and shale gas systems
- Time-resolved imaging of hydrate formation/dissociation kinetics in sediment analogs
- Wettability alteration assessment following CO₂ exposure using spontaneous imbibition NMR
- Pore-network modeling input generation via T₂ cutoff calibration against mercury intrusion porosimetry (MIP)
- Long-term caprock integrity studies through repeated NMR scanning of fractured shale specimens
FAQ
Does the MesoMR system support real-time imaging during CO₂ injection experiments?
Yes—when coupled with a programmable syringe pump and pressure transducer interface, the system acquires time-series NMR images at user-defined intervals (minimum 30 s/image) to resolve dynamic saturation fronts.
Can T₁–T₂ correlation measurements be performed on intact core plugs?
Yes—the standard configuration includes preloaded 2D inverse Laplace transform routines optimized for heterogeneous rock samples; coil sensitivity uniformity is validated per ASTM E2927.
Is third-party software integration possible for reservoir simulation coupling?
Yes—API documentation and Python SDK are provided for direct linkage to numerical simulators; example workflows for TOUGH2-NMR coupling are available upon request.
What level of technical support is included with the MesoMR Custom Series?
NIUMAG offers on-site installation, application-specific method development, and annual preventive maintenance contracts aligned with ISO/IEC 17025 competency criteria.
