Gravity and magnetic data: Iraq, Egypt and Libya

2024 is seeing a resurgence of oil and gas activity across North Africa and the Middle East, with an ongoing licensing round in Iraq, an uptick in activity in Egypt, and with Libya planning its first international tender for almost 20 years.

Getech has recovered, reprocessed and merged numerous historical data sets to generate unique compilations of gravity and magnetic to support exploration campaigns:

  • In Iraq our data archives include more than 110,000 gravity stations and 184,000 km of aeromagnetic data.
  • In Egypt our database includes 28,372 gravity stations and a compilation of 13 magnetic surveys covering ~80% of the country.
  • In Libya we have reprocessed 79,270 gravity stations and 20 magnetic surveys giving coverage over ~70% of the country.

Copper exploration

Following a series of successful projects in the last couple of years, Getech is continuing to accelerate and de-risk early-stage mineral exploration. By leveraging our geoscience expertise and proprietary data, along with our advanced in-house AI capabilities, we conduct comprehensive mineral systems analysis and structural interpretation for critical minerals, including sedimentary-hosted copper. This approach enables us to identify prospective areas within new search spaces.

Our recent successes include a collaboration with Sandfire Resources which led to their application for approximately 7,000 sq. km of copper exploration permits in Australia. Additionally, we have recently entered into a joint venture agreement with East Star Resources to further copper exploration efforts in Kazakhstan.

Our methodologies and technologies are scalable and can be adapted worldwide – find out more here.

Gravity and magnetic services

Are you maximising the application and value of your gravity & magnetic data?

Our team of gravity and magnetic specialists are highly skilled in applying these data to de-risk exploration projects, including:

  • Mapping structures in high detail and assessing fault dilatancy to understand stress-related permeability or induced seismicity risk.
  • Calculating sediment thickness and depth-to-basement, fundamental constraints for basin and thermal modelling.
  • Identifying and validating key exploration targets.
  • Mapping and categorising lateral lithological changes.
  • Building 2D and 3D models to understand basin geometry.
  • Modelling location and extent of mineral rich ore bodies.

More information on our gravity and magnetic services can be found here and if you think your team would benefit from gravity and magnetic training then take a look at our training options.

New release of Exploration Analyst streamlines energy and minerals exploration processes

A new and enhanced release of our Exploration Analyst software, used by energy and mining companies to identify new locations for petroleum, minerals, carbon storage and geothermal resources is helping to further streamline energy and minerals exploration processes.

At version 3.1, Exploration Analyst, an extension to Esri’s powerful desktop GIS application ArcGIS Pro, provides a host of capabilities for geologists and geoscientists to make better exploration decisions by improving their understanding of geologic risk and uncertainty.

Building on the functionality of previous versions, Exploration Analyst v3.1 includes the key capabilities to customise exploration maps on the fly and easily re-run analyses at the click of a button – a common business challenge for natural resources explorers when new data becomes available. These customisation options allow easy replication and standardisation, greatly increasing.

Enhancing exploration workflows even further, Exploration Analyst v3.1 can incorporate raster (grid) based analyses and automate the creation of raster outputs, eliminating the need to create each one separately. Also new in this release are search and filter functions across the toolset, reducing the user burden when ArcGIS Pro projects contain lots of data.

Read our blog for more information on the innovative features of Exploration Analyst v3.1 or learn more about how Exploration Analyst v3.1 can improve your exploration workflows and request a demonstration here.

Gravity and magnetics data: Zambia

A report by S&P Global in July 2022 projected global copper demand to double to some 50 million tonnes by 2035, driven by widespread electrification. The Central African Copper Belt is one of the most significant copper provinces on Earth. In his 2022 budgetary speech Zambia’s Finance Minister announced the country will aim to increase annual production from 760,000 tonnes in 2022 to 3 million tonnes by 2030.

Magnetic and gravity data are vital for the exploration of copper and other critical minerals. In northern Zambia a series of copper deposits are found within sediments onlapping an ancient granite horst. This mineralisation zone around the fringe of the granite body produces a strong magnetic signature, and several known deposits coincide with the prominent positive anomaly in the 2nd vertical derivative of the reduced to pole magnetics.

Magnetic data, as shown, can cost-effectively identify new search spaces for exploration. Within our global coverage, Getech retains magnetic coverage across Zambia and the whole of Africa. For more on our gravity and magnetic data coverage or our expert interpretation services, contact us at
