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.

SkyTEM groundwater survey of the Katfish Section

SkyTEM Katfish Australia

SkyTEM Australia is conducting the first-ever three-dimensional groundwater survey of the Katfish Reach section of the floodplain and part of the Gurra Gurra Lakes complex.

Data from the airborne geophysical survey will shape future management of the floodplain to restore flora and fauna including native river red gums.

Video of SkyTEM Survey over Reunion Island 2014

SkyTEM EM survey over Reunion Island

BRGM (Bureau de Recherches Géologiques et Minières – the French Geological Survey) has published a video from the SkyTEM survey over the French island Reunion conducted in 2014.

Reunion is a volcanic island with a unique morphology, located in the Indian Ocean. The purpose of the survey was to scan the top 200 metres for a 3D visualization of the subsurface of the entire island in order to map aquifers, salt water encroachment, exploitable minerals, possible landslides and other geological features. This magnetic and electromagnetic survey comprising 10,000 line kilometers using the SkyTEM technology made it possible to produce high resolution maps of the subsurface even in areas with complex, or even inaccessible, terrain. The data collected represents an immense source of useful information for geologists and will be made available to the public.

The video is in French but shows the challenging terrain of the beautiful island, and the animations give a good comprehension of the unique SkyTEM technique and equipment as well as of the 3D images created from the data collection.

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.

SkyTEM is currently mapping groundwater in Western Australia

Mapping groundwater in WA

The Government of Western Australia – Department of Water has commissioned SkyTEM Australia to conduct an airborne electromagnetic survey over the Murchison and Greenough River catchment basins as part of a Royalties for Regions funded regional water provision and management initiative.

The survey forms part of a four-year project to map groundwater resources and assess aquifer sustainability. The purpose is to assess the quantity, quality, availability and recharge of the groundwater resources in a key region which has a great demand for large supplies of low salinity water for urban water supplies, mining and agriculture without compromising the environment.

This survey, which comprises some 15,000 line kilometres of helicopter flying and covers an area of 57,000 square kilometres, is one of the largest of its kind in WA. The survey commenced in late January and will continue for several months.

“We are very proud that SkyTEM was selected for this project”, says Steven Johnson, General Manager of SkyTEM Australia. “It substantiates that the SkyTEM technology is regarded as the premier system worldwide for airborne electromagnetic groundwater mapping. The SkyTEM308 system provides accurate and reliable high-resolution data in a quick and cost-effective way”.

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.
