The main goal of this recent field study was to compare NMR-measured hydrogeologic results obtained using different high-resolution NMR tools. The NMR investigation was conducted at Ebey Island, WA. This site is in the Snohomish River estuary near Everett, WA, USA. The site is associated with a very shallow water table and a network of actively maintained dikes. NMR borehole logging measurements ...
Temperature rating In 2025, Vista Clara developed an electronics-based solution to improve the temperature rating of all Javelin and Dart downhole NMR logging tools, enabling reliable operation at borehole temperatures up to 85°C. ...
Motivation The Cosumnes River watershed system in Central California is an extremely valuable resource, supplying water for agriculture and domestic needs and provides critical habitat for natural resources. It is one of the few remaining dam-free rivers in the region with a natural salmon run and supports some of the most productive agricultural areas of California. The subbasin has been ...
Agrochemicals are chemical formulations typically used to control pests, pathogens and provide nutrients to the soil. To meet the growing demand for food, agrochemicals are used in agriculture in large quantities to bridge the gap between food production and consumption. However, the unbalanced application of agrochemicals has led to environmental degradation and poses many challenges to ...
Introduction Many critical mineral resources including lithium, uranium and potash are produced as brine groundwater resources. These critical minerals are typically found in highly saline groundwater in arid closed basins, and beneath dry lake beds. Production of brine-based mineral resources entails pumping mineral-rich brine from permeable brine aquifers and separating the minerals from water ...
Peptides refer to a class of compounds with molecular structures between amino acids and proteins, which are composed of 20 natural amino acids in different ways. They are the general term for peptides from dipeptides to complex linear or cyclic structures. We call peptides composed of 2-10 amino acids oligopeptides, also known as small molecule peptides, with an average molecular weight of amino ...
Combined with enzymatic digestion and nano-liquid chromatography (Nano-LC) technology, the separation efficiency and identification sensitivity of the sample can be improved.2. Nuclear Magnetic Resonance (NMR)NMR technology can provide structural information of proteins or peptides, including the exact location of the modification site and the structural details ...
Metabolomics is developing rapidly. In medical science research, it is hoped that analysis to identify abnormal metabolic pathways and characteristic biomarkers closely related to diseases will provide a basis for further elucidation of disease pathogenesis. Metabolomics Research Methods Metabolomics collects samples through established metabolomics research methods, and subsequently uses ...
Motivation Vista Clara NMR Geophysical Equipment helps clients image the subsurface to accurately define hydrogeologic properties including porosity, pore size, mobile and bound water content, permeability, and transmissivity. We offer equipment for sale or rent, as well as, professional consulting services to our ...
Coastal ecosystems play an important role in interfacing between marine and terrestrial environments. These systems host complex dynamic processes associated with strong physical gradients between freshwater and saltwater, ground water and surface water, and between high and low permeability soils. Therefore, the structure and stability of coastal environments have a critical impact on ...
During a recent training trip to Germany, Vista Clara provided extensive, on-site, training and equipment demonstrations to European customers to highlight magnetic resonance (NMR) technology, which enables them to directly detect and image subsurface hydrogeologic properties. The training conducted near Hanover, Germany, provided a comprehensive understanding of how NMR Geophysical Equipment ...
The Moab Uranium Mill Tailings Remedial Action (UMTRA) site is a former uranium ore-processing facility managed by the U.S. Department of Energy (DOE) in collaboration with Lawrence Berkeley National Lab (LBNL). The highest remediation priority for the site is hauling and disposal of mill tailings. Additional efforts of the site are focused on remediation of a uranium plume on the edge of ...
Vista Clara has successfully completed field testing of Javelin Micro. With a 1.75 inch (44mm) diameter, Javelin Micro is the world’s first wireline NMR logging tool capable of logging 2 inch ID PVC boreholes. Field testing was conducted at the Moab Uranium Mill Tailings Remedial Action (UMTRA) site in Moab, UT, in conjunction with a project that used the Javelin Slim 2.38 inch logging ...

We are pleased to share this excellent article on NMR from Robertson Geo, one of the world leaders in application of wireline logging technologies and techniques. Providing a deep dive into how NMR can be applied to geotechnical, hydrogeological, and mining applications, the NMR article is published in Robertson’s Summer 2021 newsletter. ...
Magnetic resonance (NMR) logging is well suited for helping manage aquifer storage and recovery (ASR) projects. An excellent example is this project in Denver Colorado, in which they used Vista Clara NMR borehole logging tools to characterize the Denver basin aquifer properties, especially hydraulic conductivity, for potential aquifer storage and recovery. The aquifers of interest are ...
This video provides an excellent overview of the techniques and benefits of combining NMR Logging tools with Direct Push capabilities. The key value proposition is the ability to leverage NMR’s superior ability to acquire unambiguous data along with Direct Push ca[ability to provide efficient, low-impact, deployment with no drilling disturbance. To see video, please click ...
One of the more challenging situations in geophysics is the need to identify and characterize aquifers in highly saline environments. Saline environments are inherently conductive, which means conventional Electrical Resistivity Tomography (ERT) techniques are less effective because the ERT signals don’t penetrate very far into highly conductive ground and the contrasts between water and ...
Motivation Denver Water required high resolution information on aquifer properties beneath the city of Denver to support planning for future aquifer storage and recovery operations. Project consultant Leonard Rice Associates recommended NMR logging as a low cost and high resolution methodology and selected the Vista Clara Javelin NMR logging tool for the ...
Motivation Two major civil infrastructure projects in the United Kingdom required accurate and precise mapping of subsurface porosity and permeability to ensure that underlying sediment formations were suitable for the intended construction. In the city of Ipswich, a new crossing over the River Orwell faced engineering risks associated with unmapped soft sediments and zones of dissolution in ...
