With our multiphysics and multiscale approach, we achieve unprecedented depth and resolution in a single project for a fraction of the cost.
All without heavy cables, induced sources, or weeks of fieldwork
Traditional exploration has long relied on seismic reflection. While very powerful for imaging lithostratigraphic horizons, dip-slip faults, and structural traps, reflection methods are expensive, logistically demanding, and not inherently sensitive to fluids or ore bodies.
The new paradigm:
By focusing on geophysical techniques that are directly sensitive to fluid-bearing and structurally complex subsurface environments, we provide rapid, affordable, and high-resolution exploration solutions.
Our passive seismic methods minimize acquisition costs, streamline logistics, and ensure fast turnaround from field deployment to actionable results, unlocking superior value for geothermal, mineral, and subsurface resource exploration.
At INVERT, we apply Deep Electrical Resistivity Tomography (DERT) to deliver high-resolution 3D images of the subsurface by exploiting natural and controlled-source electrical fields. Using portable IRIS FullWaver receivers with adjustable dipole, DERT provides deep penetration and fine lateral detail even in complex or urban terrains.
A new standard in subsurface imaging
Conventional ERT is typically limited to 2D lines and shallow depths. DERT overcomes these limitations by enabling true volumetric inversions and reaching depths of up to ~1.5 km under optimal conditions. Its logistical flexibility allows discreet, rapid deployments and significantly reduces permitting challenges.
Direct sensitivity to fluids and mineralization
DERT is especially powerful in applications where conductivity and chargeability are key indicators — geothermal exploration, groundwater mapping, and mineral prospection. By imaging conductive and polarizable bodies, it provides information that purely seismic methods cannot resolve, reducing uncertainty and enhancing exploration confidence.
Scalable, efficient, and cost-effective
INVERT tailors each survey to project scale and target depth. The result is fast acquisition, efficient processing, and actionable 3D models that de-risk decision-making across geothermal, groundwater, and resource-exploration project.
LEARN MOREINVERT applies geochemical and isotopic analyses of gases and waters to uncover the origin, composition, and evolution of subsurface fluids. These methods provide direct constraints on reservoir conditions, fluid–rock interactions, and migration pathways.
Decoding subsurface processes
By integrating chemical signatures, isotopic ratios, and thermodynamic indicators, we identify fluid sources, trace mixing processes, and detect pathways of ascent or circulation. This helps reveal the structure and behavior of geothermal, groundwater, or mineralized systems.
A foundation for robust conceptual models
Geochemical insights are combined with our geophysical results to build coherent and defensible 3D conceptual models. This integrated approach reduces uncertainty, clarifies reservoir architecture, and supports confident decision-making in exploration and resource development.

We conduct surveys worldwide, across a diverse range of challenging environments. Because our technology relies on an advanced, entirely cable-less nodal system, we are not restricted by the logistical hurdles of laying kilometers of traditional wired seismic arrays. This lightweight, modular approach allows us to deploy our sensors seamlessly in almost any terrain, from alpine mountains and dense tropical jungles to highly densed urban areas.
Project timelines vary slightly depending on the size and location of your investigation area, but our nodal and low-impact methods typically allow for much faster permitting.
For our passive seismic surveys (NANT), the process begins with about one month dedicated to permitting. Once approved, deploying our nodal system takes roughly one week. To achieve the highest quality signal, we leave the instruments in place to continuously record ambient seismic noise for 25 to 30 days. After a quick one-week demobilization to collect the nodes, our geophysics team requires less than four months to complete the data processing, interpretation, and inversion, culminating in the delivery of your final 3D model and comprehensive report.
For our Deep ERT (Electrical Resistivity Tomography & IP) surveys, permitting also takes about one month. Field operations are highly efficient, typically requiring only one week in total to cover mobilization, deployment of our nodal system, data acquisition, and demobilization. Following the field survey, we rapidly process the data and deliver your fully interpreted 3D resistivity and IP models, along with the final report, within a single month.
Our methods are highly scalable, and the survey footprint is entirely driven by your specific project goals and budget.
Because passive seismic methods have successfully been used by seismologists to image crustal geodynamics on a continental scale, the potential survey area is virtually unlimited. There is always a natural trade-off between the depth of investigation, the overall surface coverage, and the required spatial resolution. To optimize this balance, our geophysics team custom-designs every nodal array to meet your exact targets. As a baseline, a typical passive seismic survey designed to reach 5 km in depth will cover approximately 400 to 600 square kilometers, though this footprint can easily be expanded or condensed based on your needs.
Similarly, our geoelectric surveys are custom-built around your specific target. These arrays are highly adaptable, efficiently covering areas ranging from a few hundred square meters for shallow, high-resolution targets, up to several square kilometers for deeper exploration.
To ensure the highest quality data acquisition, we utilize industry-leading, autonomous sensor technology tailored to each specific method. Our equipment is selected specifically for its high signal-to-noise ratio, reliability in harsh environments, and cable-less deployment advantages.
We deploy SmartSolo IGU-16HR 3-component (3C) nodes. These state-of-the-art, cable-less geophones are specifically optimized to extract high-fidelity ambient noise from continuous seismic records.
Hardware Specifications:
Natural Frequency: 5 Hz (ideal for capturing the low-frequency ambient surface waves required for passive seismic).
Timing Accuracy: ±10 µs, GPS-disciplined clock. Precise synchronization across the array is critical for accurate cross-correlation of ambient noise.
Endurance: Up to 30 days of continuous recording at a 2 ms sample rate, completely autonomous.
Environmental: IP68 waterproof rated, allowing for deployment in extreme weather conditions.
For our geoelectric surveys, we install networks of IRIS FullWaver systems composed of autonomous V-FullWaver (voltage receivers) and I-FullWaver (current loggers) nodes, allowing for virtually unlimited array expansion and custom 3D geometries. These distributed, independent receivers allow us to conduct high-resolution, deep 3D Electrical Resistivity and Induced Polarization (IP) imaging without the logistical constraints and physical footprint of traditional multi-electrode cables. By separating the transmitter and receiver arrays, we can achieve dipole separations capable of imaging targets at depths exceeding 500 meters, far beyond the limits of standard cabled ERT systems.
We provide comprehensive, high-resolution 3D subsurface models. Because we understand the importance of fitting seamlessly into your team’s existing workflow, our deliverables are exportable in multiple industry-standard formats.
This means our fully interpolatable 3D volumes, 2D cross-sections, and 1D profiles can be easily superimposed and integrated with the geophysical data, geological models, and historical drill logs you already have available. We deliver data ready to be imported into leading earth-modeling software, ensuring your geologists and engineers can immediately put the results to work.
