Danish water alliance to help solve California’s water challenges

WTA

To make sure California is able to cope with an unprecedented drought Governor Brown signed what is perhaps the most significant legislative water initiative in California in half a century – the Sustainable Groundwater Management Act. 

Over the last two decades Denmark has established itself as a world leader in water technologies.  Last week SkyTEM and  seven other Danish companies met in San Francisco to launch The Water Technology Alliance (WTA) – an initiative to create a collaboration platform between California and Denmark focused on delivering solutions for California’s water challenges.  SkyTEM is looking forward to working with Californian stakeholders and Danish collaboration partners to develop water solutions for the future that can be utilized not only in California but across the globe where, according to the World Economic Forum 2016, water crises is expected to be one of the greatest issues in the coming decade.

SkyTEM survey for groundwater mapping in Botswana

The International Water Management Institute (IWMI) has published an article about their groundwater mapping project over the Ramotswa Aquifer on the border between South Africa and Botswana.

“This is tremendously useful for us,” said IWMI’s Karen Villholth who leads the initiative. “By digitally mapping the subsurface in this way we can work out where the important aquifers are located, how large and deep they are, how they are delimited by other geologic formations. From this we can determine where it would make sense to further explore the aquifer through traditional means to identify good sites for drilling and managed aquifer recharge.”

SkyTEM improves chances of finding water in drought stricken California

SkyTEM mapping water in California

SkyTEM began mapping aquifers in the Central Valley of California as well as Barstow area earlier this year. The SkyTEM508 system has now returned to continue mapping farm lands in the Central Valley.

A recent groundwater mapping project in Australia showed that drilling alone is a hit-and-miss technique in which there is just a one-in-five chance of finding water and even less chance of finding water of suitable quality. SkyTEM’s accurate high resolution data has been used to improve the success rate to better than 1 in 3.

SkyTEM quickly completes Geoscience BC Peace Project with SkyTEM312FAST

Peace_Project_Geoscience_BC

SkyTEM Canada Inc is pleased to announce completion of Geoscience BC’s Peace Project in northeast B.C.

The Peace Project, designed to provide sound technical knowledge of the region’s aquifers, is a collaborative effort involving the BC Oil and Gas Commission, the BC Oil and Gas Research and Innovation Society, ConocoPhillips Canada, the Ministry of Environment, the Ministry of Forests, Lands and Natural Resource Operations, the Ministry of Natural Gas Development, Northern Development Initiative Trust and Progress Energy Canada Ltd.,  with additional support from the Peace River Regional District.

All data acquisition, comprising approximately 21,000 line kilometres and covering 8,000 square kilometres was completed in only 43 days.  This exceptional production rate was achieved with SkyTEM’s breakthrough technology – SkyTEM312FAST, the world’s fastest helicopter-borne geophysical system.

Engineered with a rigid aerodynamic carrier frame SkyTEM312FAST remains straight and level during high-speed flight benefiting data quality as well as survey efficiency and economy. Dr. Flemming Effersoe, SkyTEM’s CEO, stated “it means a great deal to me to have SkyTEM selected for this important project and we are proud of what we accomplished in British Columbia in such a short time. Our team delivered accurate high resolution data every 48-72 hours throughout the project. Combined with our ability to detect subtle geological contrasts in the top 400 m, at 150 kilometres per hour, this technology is of significant value to the global mineral and oil & gas exploration communities as well.”

Contributing to the unprecedented SkyTEM data acquisition rate and quick completion of the project was the communications expertise of Mr. Reg Whiten, President of InterraPlan Inc., who worked closely with local First Nations, the SkyTEM field crew, Devbrio Géophysique Inc, who adjusted day to day flight plans to accommodate First Nations cultural events and hunting season requirements and the logistics support and skills of pilots from Bailey Helicopters Ltd.

Mr. Carlos Salas, Vice President, Energy at Geoscience BC said “the Peace Project has collected valuable information. Without the cooperation of everyone, especially the local community, the results would have been much different.”

Information from the Peace Project will serve as a key component of the Northeast Water Strategy by providing knowledge to enable the Strategy’s Enhanced Water Monitoring System. The Northeast Water Strategy is currently under development by the Provincial government with cooperation from Treaty 8 First Nations, local governments, regulatory bodies, and the resource sector.

SkyTEM appreciates the opportunity to map the earth’s critical resources and are proud to have played a role in this vital project.

Combined SkyTEM and AIRGrav Survey in Hope Bay, Nunavut

SkyTEM Nunavut

SkyTEM Canada Inc is pleased to report that data acquisition on TMAC Resources’ Hope Bay and Elu gold mining projects in Nunavut has begun. SkyTEM and Sander Geophysics have teamed to acquire over 15,000 line kilometres of combined electromagnetic, magnetic and gravity data over TMAC’s properties. The airborne data will be used to supplement previous exploration carried out on the Greenstone belt, helping TMAC create Canada’s next major gold mining camp.

The Hope Bay airborne exploration program includes:

  • A SkyTEM516 electromagnetic and magnetic survey over the Hope Bay and Elu properties. SkyTEM516, a dual moment system, is capable of delivering a dipole moment of more than 1,000,000 NIA. A uniquely engineered receiver design reduces the noise level by a factor of 20 for the collection of accurate high resolution data from the near surface to depths of several hundred metres. In early 2015 SkyTEM516 demonstrated its depth and resolution capabilities by mapping the deep and weakly contrasting Caber Deposit in Québec, Canada. Caber results can be seen here.
  • A Sander AIRGrav purpose built airborne gravimeter to acquire high resolution helicopter gravity data over the Elu North and South survey blocks. This unique gravimeter is mounted on a three-axis inertially stabilized platform, combined with extremely accurate Differential GPS (DGPS) to correct for aircraft movement and vibrations. AIRGrav offers a number of advantages over competing systems, including: 1) significantly better resolution and accuracy; 2) ability to operate under turbulent 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.
  • 24/7 data acquisition. SkyTEM is managing the surveys and, together with Sander Geophysics and field crew from Devbrio Géophysique Inc, has mobilized a team of 7 professionals, including helicopter pilots, to Hope Bay to take advantage of available daylight hours in Nunavut and maximize daily data acquisition. TMAC’s infrastructure contributes to survey efficiency with the availability of three camps, air strips, roads, fuel storage, a port and power plants. Preliminary data and 1D EM inversions are being delivered every 48 hours throughout the project.

Along with Gravity/Mag/EM data, post processing of Airborne IP signatures will also be completed. If unique geophysical indicators can be defined for the various styles of mineralization at Hope Bay it will significantly improve future exploration targeting and reduce future exploration expenditures and timelines to success. SkyTEM and Sander are both proud to play a part in this important Canadian gold mining project.

SkyTEM data accuracy maps depth to and thickness of Nebraska aquifers

SkyTEM EM survey

In 2013 SkyTEM304 collected data over 99-square miles of Eastern Nebraska to provide critical information on the condition of aquifers in areas suffering from declining water levels.  According to management of the Lower Platte South Natural Resources District (LPS NRD) SkyTEM’s accurate high resolution results provide extensive information about the area’s geology, aquifer characteristics and water in storage.  The NRD’s use of the data is on-going.  The data is intended to help landowners in the project area access data showing the depth to aquifer material, the thickness of the aquifer and other basic information.  The information collected is also available for download and can be found here.

Once on the LPS NRD site scroll down to Interactive Map (5.5MB). for a full interactive map with aquifer information about individual tracts of land.  You will need to have a version of Google Earth installed on your computer. Once the maps open click any blue-shaded point to see detailed information about the aquifer.

SkyTEM survey doubles the chances of striking water

SkyTEM survey finding water

SkyTEM304 data has been successfully used to optimise the drilling programme over a water well-field in the Lower Gascoyne River in Western Australia for the Department of Agriculture and Food WA (DAFWA).

Dr Richard George, DAFWA’s principal research scientist, says “We’re running better than a one-in-three success rate of finding sufficient water-bearing sands…”.  Read more about the success of the survey here.

SkyTEM Australia will build on this successful 2013 SkyTEM304 survey by commencing Phase 2 of this project over the Middle Gascoyne River.  Currently, none of the water along the Gascoyne River east of Rocky Pool is used by the Carnarvon horticultural district.  The Middle Gascoyne investigation will assess the volume of good quality water available in the middle Gascoyne river channel upstream of the horticulture district and will involve the SkyTEM304 survey and analysis of the resultant data.

 

SkyTEM Africa has adopted a lion

????????????????????????????????????

SkyTEM Africa has adopted the male lion “Gaucho” who lives in the Drakenstein Lion Park in South Africa. Gaucho was rescued from a Chilean Circus.

SkyTEM’s regional sales manager for Africa, Vasco Nunes, just had to do it when he learned about the heart-rending stories of the lions, and he also adopted four other lions personally.

The adoption fee paid by SkyTEM contributes to the care costs of the lion, including food, veterinary and housing costs.
