Cryogenic Nanopore NMR Analyzer

NMRC12 series is a NMR-based nano-pore analyzer used to study the pore structure and distribution of porous materials. The determination of pore distribution can be measured and calculated by applying the relationship between the pore size and the freezing point of pore fluid. This NMR technique could be used to monitor the phase transition in pore fluid in real time and the detection range of pore size falls in 2 to 500 nm if appropriate fluid samples are chosen.

MicroMR Rock Core NMR Analyzer

MicroMR hardware configurations range from 2MHz to 5MHz operating frequency, and cover sample sizes from standard 1” or 1.5” plugs up to full size (6”) cores. Pulsed field gradients are available as an option for measurements based on diffusion or imaging, and all versions are compatible with overburden cells offered by third party manufacturers.

A primary goal of MicroMR is to make NMR core analysis measurements accessible to non-NMR experts. To this end, various levels of software capability are matched with and integrated into the hardware options to enable MicroMR users to be productive whatever the level of their NMR knowledge.

Entry level MicroMR Systems come complete with LithoMetrix™ software which carries out the more routine functions such as T1 and T2-based pore size distributions, porosity, and fluid mobility measurements such as Free Fluid Index (FFI), Bound Volume Irreducible (BVI) and Clay Bound Water (CBW). Higher performance hardware is matched with greater software capability including hydrogen index, permeability and fluid typing by 2-D data mapping.

MicroMR systems allows users to obtain Pc measurements 5 times faster, while getting up to 10 times as many data points per scan, compared to traditional measurement techniques.

All MicroMR systems also allows measurements to be made up to four times faster, with echo spacings (TE) several times shorter, than in previous instruments.

Short echo spacings are essential for measurements on tight rock core NMR  and shales, which have a high proportion of small pores. This allows for the correct representation of the pore size distribution and provides accurate porosity measurements.

 

Improved Performance

  • Signal to Noise doubled compared to previous generation instruments – lets you collect better data in the same time, or collect your data four times faster.
  • Better data for tight rocks – improved measurement of fluids in smaller pore spaces, by substantially decreasing acquisition times and allowing very short echo times.
  • Fastest, most accurate capillary pressure measurement on the market – the patented GIT-CAP measurement is 5 times faster than the traditional special centrifuge method, while providing 10 times more data points, without destroying the core.

Modularity throughout the rock core analyzer

  • Core sizes from 1” to 6”.
  • Magnets from 2 MHz for optimum well log calibration to 5 MHz for the best diffusion and imaging experiments.
  • 1-D, 2-D, and 3-D gradients for diffusion studies.
  • High performance, modular electronics, with a range of options for various performance levels.
  • Multi-level software, matching capability to requirements, from new user to advanced research.

Core NMR Analyzer

It is a well known fact that nuclear magnetic resonance (NMR) is commonly used in well logging measurements and for routine laboratory core analysis. However, many are not aware of the principle behind NMR and its advantages for the core analyst. It is commonly used to determine porosity and pore size distributions but it is important to note that NMR can also measure fluid mobility parameters such as bound volume irreducible (BVI), free fluid index (FFI), clay bound water (CBW) and effective porosity.

NMR can also easily and effectively measure permeability, capillary pressure, and oil/water and gas/water contents. These parameters are measured with high level of precision using comprehensive software, which is user-friendly and can be easily operated by a novice in NMR. The technical details given below are aimed at introducing NMR to the petrophysicist and core analyst who are not very familiar with NMR.

When a sample is placed in a magnetic field and activated with a quick pulse of radio frequency (RF), NMR signals are generated from liquids such as brine or oil. An NMR signal is formed instantaneously after the pulse, which then dies away with a characteristic decay rate or relaxation time known as T2. The signal amplitude immediately after the pulse indicates the total amount of fluid present. T2 of the signal provides important information about the physical environment of the liquids.

In pores filled with a single fluid, there are two key components to the NMR signal, one signal is generated from the fluid far from the pore walls and another close to the pore walls. The nature of NMR signals in fluids far from the pore walls is similar to those from bulk fluids having comparatively long relaxation times, whereas fluids close to the pore walls undergo a process of adsorption and desorption with the pore walls which has the effect of drastically reducing their NMR relaxation times.

In large pores, the dominant effect is from the bulk fluids, so larger pores have longer NMR relaxation times. In smaller pores, the surface-to-volume ratio is much higher, hence the fluids near the pore wall dominate the NMR signal, and smaller pores display overall shorter NMR relaxation times. This process is illustrated in the figures below.

Of course, practically it may not feasible to take NMR measurements from individual pores. The entire core must be measured at once, hence the resulting NMR signal is a composite of all the NMR signals from the different pore sizes in the core.
