Geophysics plays a central role in enabling us to understand the Earth’s subsurface. It allows geoscientists to measure variations in physical properties such as density, magnetisation, conductivity and elasticity, then convert those measurements into insight about geology, structure and resource potential.
As it provides a non-intrusive means of investigating the subsurface at a range of scales, geophysics has become essential for energy, minerals, engineering, environmental assessment and national infrastructure planning.
Metatek applies a suite of advanced geophysical exploration methods through high resolution airborne, marine and terrestrial programmes.
Our expertise sits particularly within potential field data acquisition and processing, including gravity, gravity gradient, magnetic and electromagnetic techniques. This integrated approach strengthens subsurface imaging in areas where conventional seismic alone may struggle, such as complex carbonates, basement terrains, regions with strong volcanic cover and structurally challenging frontier basins.

One of the most important uses of geophysics is to define major geological architectures. Variations in density, conductivity and magnetic properties reveal contrasts between rock units, allowing interpreters to assess:
Metatek routinely delivers regional to prospect scale mapping by combining gravity, eFTG gravity gradient and magnetic data.
Our geophysical exploration in areas such as Upper Egypt demonstrates how advanced potential field methods uncover deep structural frameworks where seismic penetration is limited. These datasets often reveal structural inheritance and faulting regimes that influence petroleum systems and mineralisation.
In both established and frontier hydrocarbon provinces, geophysics supports exploration teams by reducing uncertainty before drilling. Potential field data are used to:
Metatek’s airborne gravity gradient surveys with the advanced eFTG instrument have been deployed globally for these purposes. The eFTG system offers exceptional sensitivity to subtle density differences which can highlight faults, uplifted blocks or sedimentary thickness changes relevant to charge, migration pathways and trap formation. Metatek’s proprietary processing workflows and software, aligned with Lockheed Martin’s system capabilities, ensure that data quality and interpretability remain high even in difficult terrain.
Geophysics is also increasingly important for energy transition studies. Gravity, magnetics and electromagnetic methods help identify natural hydrogen plays, geothermal potential and geological settings suitable for carbon storage. Several of Metatek’s clients operate in these emerging sectors, enabling integrated geoscience assessments that go beyond conventional exploration.
Mineral systems often express strong physical contrasts, making geophysics a valuable tool for screening and target definition. Magnetic data are widely used to locate:
Gravity and gravity gradient data can highlight dense ore bodies or intrusive systems associated with mineralisation. In terrains with limited outcrop or deep weathering, these methods provide essential context that guides drilling programmes and ground truthing.
Metatek has extensive experience integrating magnetic, gravity and hyperspectral data to support mineral exploration workflows, particularly in remote or logistically challenging regions where airborne acquisition is the most efficient strategy.
Geophysics assists environmental and hydrogeological studies by mapping shallow subsurface features relevant to water resources or environmental risk. Applications include:
Electromagnetic methods, gravity and magnetic surveys help establish the geological context needed for sustainable water management and environmental planning. The Metatek team has deployed mixed method surveys in areas where both resource potential and environmental sensitivity require a balanced, data driven approach.
Major engineering projects rely on geophysical information to reduce uncertainty in ground conditions. Before construction begins, geophysics can identify:
High resolution ground and airborne surveys help engineers anticipate geotechnical challenges early in the project timeline. Our experience in complex terrains allows us to support engineering teams operating in regions with strong topographic relief, surface access restrictions or variable lithologies.
Geophysics contributes to understanding and mitigating natural hazards by imaging features associated with:
Magnetics, gravity and electromagnetic methods provide additional layers of insight when combined with seismic or geological data. Metatek’s work in structurally diverse regions enables us to characterise the tectonic frameworks associated with long term hazard assessments.
Our Geophysical exploration services are utilised across these application areas. Our service is strengthened by several core capabilities:
Our R & D focus has led to bespoke processing tools that maximise information content by exploiting mathematical relationships across multiple data channels. This ensures that every dataset is processed to a standard suitable for detailed geological interpretation rather than simply reconnaissance level mapping.
Geophysics is used to illuminate the structure and composition of the Earth, supporting activities ranging from resource exploration to engineering design and environmental stewardship. When executed at high resolution with strong technical oversight, potential field methods provide a powerful complement to seismic and geological datasets.
Metatek specialises in delivering these advanced geophysical solutions. Through high quality data acquisition, rigorous processing and integrated interpretation, we help clients understand complex subsurface environments and make better informed decisions across the full spectrum of geological and engineering challenges.
