Magnetic Resonance Technology: from Medical to the Oil Industry

Recorded On: 06/30/2020

The discovery of Nuclear Magnetic Resonance (NMR) phenomenon spawned innovative diagnostic technologies that facilitated advancements in a wide range of disciplines including medicine, chemistry and earth sciences. Geologists observed that in a manner similar to Magnetic Resonance Imaging (MRI) that revolutionized medical imaging, NMR measurements illuminate pore-filling fluids inside a porous rock and provide unique insight to porosity, pore size and/or fluid viscosity without any damage to the sample. 

For the oil and gas industry, this sensor technology has become everyday reality with the development of NMR well-logging tools. Since the first modern NMR logs in the early 1990s, NMR logging enhanced formation evaluation in complex reservoir rocks such as heterogeneous carbonates and silty sands and enabled reservoir fluid characterization in the presence of fresh water, heavy oil or variable gas-oil ratio. More recently, with the development of logging-while-drilling (LWD) tools, NMR petrophysics is available for real-time reservoir navigation decisions. 

With these advancements, upstream operators can realize significant value in their exploration, evaluation and field development activities. First, owing to the more accurate reservoir quality and fluid mobility evaluation, the cost and time savings by optimizing formation testing, sampling and well testing operations outweigh the costs associated with NMR logging in many cases. Second, NMR logs help discover and assess challenging reservoirs with low resistivity contrast in the presence of laminar shales or carbonate microporosity. Finally, NMR-driven placement of injector and producer wells reduces field development costs and potentially increases hydrocarbon recovery.

This lecture shares the lessons of two decades of learning by an experienced operator with field examples that show how to increase operational efficiency and improve reservoir understanding with wireline and LWD NMR logging technology.
