Latest Phase of Ireland's Tellus Airborne Geophysical Survey Data Released

March 2018 - The Geological Survey Ireland has released geophysical data Sander Geophysics acquired during the spring and summer of 2017, over counties Donegal and Mayo. SGL´s de Havilland Twin Otter (registration C-GSGF) gathered over 46,000 lkm of data using SGL's multi-parameter platform, which includes the high resolution SGFEM four frequency electromagnetic system. Koen Verbruggen, Director of Geological Survey Ireland stated “We’re pleased to have successfully completed the latest phase of Tellus surveying and the high-quality geoscience information is vital to the work carried out by the Geological Survey as well as wider stakeholders in areas of radon prevention, groundwater supplies, mineral exploration and agriculture.” Sander Geophysics looks forward to returning to Ireland this spring to complete the next phase of this important project.

SGL Data Lead to Positive Mineral Results in Ireland

December 2017 - BTU reports exploration success following up on anomalies initially identified from data acquired by Sander Geophysics as part of the Tellus geoscience mapping programme in Ireland. SGL acquired magnetic, radiometric and electromagnetic data for Tellus starting in 2011-12, and between 2015 and 2017 three more surveys were completed. The latest Tellus contract win for Sander Geophysics (see November announcement) means three more years of acquiring these important data in new regions of Ireland starting in 2018.

Study says methane could be cut for 'near zero' cost, and SGL can help focus those efforts

November 2017 - A recent study from David Tyner and Matthew Johnson, two Carleton University professors, suggests that methane emissions could be significantly reduced for minimal cost. The authors also point out that the actual amount of methane being released is in most instances only estimated, and they say those estimates may be 50% too low. Sander Geophysics offers airborne methane mapping using SGMethane to find and quantify leaks in infrastructure used for producing, processing, storing and transporting natural gas, oil and other hydrocarbons, and to monitor and quantify all sources of methane emissions. SGMethane reveals all sources of significance, irrespective of awareness of infrastructure existence and location. Having this kind of accurate geo-located data allows responsible organizations and governments to focus methane reduction efforts, and work efficiently to reduce large emitters.

Sander Geophysics Awarded Three Year Contract to Fly Multi-Parameter Surveys in Ireland

November 2017 - The Geological Survey of Ireland (GSI) has awarded Sander Geophysics a three year contract to fly a large airborne magnetic, radiometric and electromagnetic project in southern Ireland. This project is a continuation of the Tellus surveys that Sander Geophysics flew in 2011-12 and 2015-17. As in the previous surveys, high resolution electromagnetic (EM) data will be acquired using Sander Geophysics' unique SGFEM frequency domain EM system, along with magnetic and radiometric data. According to the GSI, the airborne geophysical data will be used "for geological mapping, resources assessment, mineral exploration, environmental management and geological and environmental research". SGL is very proud of this award and looks forward to continued close collaboration with GSI on this important project.

For the 8th Year AIRGrav Goes to Antarctica with NASA

October 2017 - SGL is very proud to once again be involved in NASA's IceBridge project. This is the eighth year that SGL has supplied its industry leading AIRGrav airborne gravimeter to assist with NASA's polar research. This campaign will be flown from the end of October to the end of November based in Ushuaia, Argentina. As explained by NASA: "This is a new base of operations for IceBridge, which normally flies to Antarctica from Punta Arenas, Chile. The reason for the switch is that this fall, IceBridge scientists and instruments are traveling aboard a P-3 aircraft, which has a shorter range than their regular Antarctic ride, a DC-8."

The mission of Operation IceBridge is to collect data on the changing polar land and sea ice and maintain continuity of measurements between ICESat missions. The original ICESat mission ended in 2009, and its successor, ICESat-2, is scheduled for launch in 2018.

CGG Requests a Retraction

October 2017 - Sander Geophysics regrets having made some statements concerning CGG in a keynote address of the Exploration '17 conference on October 23rd that have been identified as being factually incorrect and provides these corrections and clarifications. CGG is in a financial restructuring process and is not bankrupt. CGG Multi-Physics (including CGG Airborne) is a core part of the CGG offering and was incorrectly stated as being for sale.

Final Flight in Ireland for 2017 Marks Major Tellus Milestone

October 2017 - The final flight of the 2017 Tellus survey marks a significant milestone with more than 50% of Ireland officially "mapped". Over 46,000 lkm of data were acquired this year using SGL's multi-parameter platform, which includes the high resolution SGFEM four frequency electromagnetic system. Minister for Natural Resources, Séan Kyne, TD, stated that: "The new data will further reveal the geological make-up of Ireland demonstrating the benefits of the Tellus Programme which include protecting public health, increasing agricultural productivity and allowing for a greater understanding of the country’s natural resources." Data from all of the previous Tellus surveys are available for download at no charge on the Tellus website, and the newly acquired data will be available in the spring of 2018.
