Called critical to training new generation of petroleum engineers

Oxford Instruments Magnetic Resonance, the leading supplier of low-field benchtop nuclear magnetic resonance (NMR) technology, offers a range of GeoSpec rock analyzers including the MARAN Ultra. The University of Oklahoma uses a total of seven of these instruments in undergraduate education and research.

According to Dr. Carl Sondergeld, professor and associate dean of the University of Oklahoma’s Mewbourne School of Petroleum and Geological Engineering, the instruments are ideal for evaluating the petrophysical properties of rocks, allowing for petroleum engineering to characterize a reservoir and conduct economic evaluations of its potential.

“NMR is a technology of the future that we are introducing to a new generation of petroleum engineers“, said Dr. Sondergeld, who uses the instruments in petrophysics and reservoir mechanics courses, as well as for conducting research. “It is absolutely essential that we focus on exposing our undergraduates to this technology and give them hands on experience so they can bring this knowledge with them when they are employed in industry. NMR provides more accurate information, potentially allowing for efficient oil and gas production from oil companies.”

Students use the MARAN Ultra instruments to run a series of experiments on rocks to obtain measurements of porosity, capillary bound fluid, free or producible fluid, and pore body distribution and size. The instrument runs at the same frequency as downhole NMR logging tools (2MHz), so information from core measurements is directly applicable to the interpretation of downhole logs. In addition, the instrument is being used in research establishing a framework for interpretation of NMR in shale reservoirs.

The MARAN Ultra is a versatile, low cost benchtop imaging system now available with a graphic user interface to facilitate image acquisition. The system can be used to conduct a wide variety of MRI and bulk NMR experiments and is specifically designed for research use. Depending on individual user requirements, the modular design of the MARAN Ultra allows for various configuration options and therefore offers outstanding functionality.

The MARAN Ultra has been designed to offer flexibility to the research user of low-field NMR. Its real-time interactive software puts full power into the hands of the expert user. Real-time signals can be observed on the analyzer’s PC monitor while acquisition parameters are adjusted “on the fly”, and parameter sets can be saved and recalled.

The MARAN Ultra is able to collect large data sets, useful for accurate T2 determinations, especially where multiple T2s may be present. Sets of measurements using different parameters can be sequenced through Visual Basic scripting without user intervention, using ActiveX™, from Excel, Matlab or similar programs.

Accessories such as bipolar pulsed field gradients are available for diffusion and profiling experiments. Optional liquid or gas-flow controlled variable sample temperature and multi-nuclear probes add to the Ultra’s research capabilities.

Oxford Instruments Magnetic Resonance is committed to the development and manufacture of cost-effective instrumentation for industrial quality control, research, and life sciences. The group's expertise is based on Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) technology. Today Oxford Instruments is exploring more innovative ways to use benchtop NMR for faster, easier, and safer measurements.

Notes to editors

Oxford Instruments aims to pursue responsible development and deeper understanding of our world through science and technology. We provide high technology tools and systems for industrial and research markets based on our ability to analyze and manipulate matter at the smallest scale. Innovation has been the driving force behind Oxford Instruments’ growth and success ever since the business spun out from Oxford University over 50 years ago, and its strategy is still to effect the successful commercialization of these ideas by bringing them to market in a timely and customer-focused fashion. Oxford Instruments is now a global company with over 1,300 staff worldwide and a listing on the London Stock Exchange.

Our objective is to be a leading supplier of next generation tools and systems for research and industry. This involves the combination of core technologies in areas such as low temperature and high magnetic field environments, nuclear magnetic resonance, X-ray electron and optical based metrology, and advanced growth, deposition, and etching. Our products, expertise, and ideas address global issues such as energy, environment, terrorism, and health, and are part of the next generation of telecommunications, energy products, environmental measures, security devices, drug discovery, and medical advances.
