SkyTEM mapping water in California

SkyTEM contract USGS

SkyTEM has been  awarded a competitive USGS contract for an airborne magnetic and electromagnetic geophysical survey at the Fort Irwin National Training Center (NTC) in California. The purpose of the survey is to map the complex geological framework, lithologic variations and structural controls (faults and folds) on groundwater within a series of basins within portions of the (NTC).

The data will be used for numerical inversion to determine the 3D extent of structural geologic features as well as to constrain models of the geologic and tectonic evolution of the region. The results will be used to create a geological framework to be input into groundwater flow models.

XRI Conducts SkyTEM Survey in Eastern Nebraska

SkyTEM system

Exploration Resources International Inc. (XRI) is conducting an Airborne Electromagnetic (AEM) Survey under contract to the Eastern Nebraska Water Resources Assessment (ENWRA). ENWRA is a coalition of six Natural Resources Districts (NRD’s) in the glaciated area of eastern Nebraska Including Lewis in Clark, Lower Elkhorn, Papio-Missouri, Lower Platte North, Lower Platte South, and Nemaha. XRI will collect the AEM data using the SkyTEM (Aarhus, Denmark) SkyTEM508 system flown by SkyTEM Canada Inc. (Ontario, Canada ) with subcontractors Southern Helicopters Inc. (Baton Rouge, LA) and Devbrio Geophysique Inc. (Quebec, Canada).

This survey is to continue a reconnaissance study of eastern Nebraska, that was begun in the northern portions of eastern Nebraska in October of 2014, by collecting approximately  700 line miles of data south of the Platte River to the Kansas State boarder in Butler, Saunders, Seward, Sharpy, Douglas, Lancaster, Cass, Otoe, Johnson, Nemaha, Richardson, Pawnee, and Gage counties.  XRI will use the AEM data collected to develop a hydrogeological framework of the area.  Results of this study will be delivered to ENWRA in July of 2015.

The World’s First Helicopter TEM/Gravity/Mag Systems

Canada 2015

SkyTEM and Sander Geophysics have teamed to offer combined deep looking MultiMoment® helicopter TEM systems with high resolution AIRGrav technology.

SkyTEM’s recent R&D efforts have led to an increase of the dipole moment to over 1,000,000 NIA. This high powered system, SkyTEM516, is yet another breakthrough in SkyTEM’s TEM technology.  The system was flown over the industry standard test site, Caber, in conjunction with Sanders’ AIRGrav system to compare SkyTEM data with other transient EM systems and to demonstrate the added value of including high-resolution airborne gravity data over complex mineral deposits. The case study utilizing the combined systems will be showcased at the Toronto PDAC in March 2015.

SkyTEM is the inventor of MultiMoment® TEM systems and holds a patent for this technology. All SkyTEM systems utilize MultiMoment® technology to deliver the combination of accurate high-resolution maps of subtle variations in geology from the very near surface to depths of hundreds of meters. An array of systems is available with a diverse range of map products. Inversions are available within 24 hours of acquisition and the company is proud to offer raw data for critical analysis.

AIRGrav is Sander Geophysics’ purpose built airborne gravimeter. This unique gravimeter is mounted on a three-axis inertially stabilized platform, combined with extremely accurate Differential GPS (DGPS) to correct for aircraft movement due to turbulence and aircraft vibrations. AIRGrav offers a number of advantages over competing systems, including: 1) significantly better resolution and accuracy; 2) ability to operate under normal daytime flying conditions; 3) ability to provide high quality gravity data while flying in drape mode; 4) significant operational efficiencies; and 5) shorter time required for data acquisition and processing.

This combination of cutting edge helicopter-borne technologies on a single cost effective platform offers economic solutions to all exploration sectors. High resolution EM and gravity data can now be collected concurrently, and surveys can be drape flown at low altitudes and at lower speeds than fixed wing aircraft.

XRI and SkyTEM partner to deliver solutions for water exploration

geophysical water exploration partnership with XRIPartnership for geophysical water exploration

Exploration Resources International Geophysics, LLC (XRI) and SkyTEM Surveys (SkyTEM) have partnered to combine advanced methodology and technology for the exploration of water resources. As the world increasingly consumes water resources, management of these resources requires appropriate, reliable and timely information to ensure water is available when and where it is needed. This collaboration brings together highly developed expertise to deliver solutions focused on the acquisition, modeling and characterization of groundwater resources. The partnership combines years of XRI’s best-in-class geophysical and hydrogeological expertise with SkyTEM’s state-of-the-art airborne aquifer mapping technology. This combination of leading-edge knowledge and tools for assessing fresh and saline water resources will help communities, industries and resource sectors manage these limited and vulnerable resources sustainably, today and into the future. “Combining XRI’s hydrogeological expertise with SkyTEM’s advanced and focused helicopter-borne data acquisition systems allows us to deliver superior and accurate geological and hydrogeological information to governments and private industry at a time when it is needed most” said Jared Abraham, an XRI Senior Research Geophysicist. “High resolution images of the earth’s subsurface combined with our team’s knowledge and expertise at assessing water resources makes it possible for us to deliver critical and much needed information. Those faced with the challenges of properly managing their groundwater can now make informed and appropriate decisions”. Groundwater is one of the nation’s most important natural resources and it is increasingly essential to provide effective programs for management of aquifer systems worldwide. Proper management requires thorough knowledge of the aquifer system. This includes dependable information on geographic extents, volume, water quality recharge and outflow levels. SkyTEM’s airborne electromagnetic (AEM) systems are non-invasive and provide a quick economic method for mapping groundwater, particularly for large areas or areas where land access is limited or difficult. XRI interprets the airborne data to deliver 2D and 3D images used to build hydrogeological frameworks for groundwater quality investigations, groundwater flow modeling and groundwater management planning. “SkyTEM was developed specifically to map aquifers and this partnership allows us to deliver superior map products to our clients while meeting their specific needs and schedules” said Bill Brown, Regional Manager, SkyTEM Canada. “XRI’s capabilities and experience add a tremendous amount of value to our data and by working with us, our clients can now receive the full benefit from the quality and thoroughness of our work. Together we share a commitment to collecting and delivering the best possible data available in the market today.”
