Application of Magnetic Resonance Imaging in the Energy Sector

In the petroleum and porous media sectors, low-field nuclear magnetic resonance (NMR) technology is playing an increasingly pivotal role. It not only supports conventional evaluations such as exploration and development of low-permeability oilfields, gas fields, and coalbed methane, but also enables non-destructive and rapid imaging of rock internal pore distribution and spatial fluid relative saturation. By integrating different functional modules, such as low-temperature high-pressure or high-temperature high-pressure modules, research under a wide range of temperature and pressure conditions becomes possible. This allows the data collected to more closely reflect subsurface conditions, providing comprehensive application solutions in the field.

Case Study 1: Full-Diameter Core and Short Relaxation Sample Imaging Analysis

Using a 150mm large-diameter core analyser, imaging analysis of full-diameter cores provides a more accurate reflection of actual formation conditions.

Case Study 2: Waterflooding Experiment – NMR Imaging Analysis

Oil saturation is calculated based on the accumulation of image pixel intensities.

As the displacement progresses, oil saturation at the inlet initially decreases, accompanied by a clear propagation process. NMR visualisation provides a non-destructive and reliable method for rapid core oil saturation measurement and enables calculation of local saturation at specific positions within selected slices. *Warm colours indicate oil, blue indicates water.
