From the Sahara to Vietnam:
we know where to drill.

Ingeniero frente a una planta industrial

Twenty-three freshwater projects and seventeen geothermal surveys across thirty countries — from the Vietnamese highlands and the Wahiba sands to the Crimean peninsula, the Mongolian steppe, and the Sahara. Each one resolved the same question without a single exploratory drill: where exactly to drill, how deep, and what flow rate to expect.

Geothermal source survey — two anomalies, one section

Anomaly 1T: continuous to 3 668 m  ·  Anomaly 2T: 0–263 m + 3 534–3 654 m  ·  geothermal water flow at depth

In 2024, Inside Earth surveyed a Vietnamese site for geothermal resource. The remote workflow generated a vertical depth section of the survey area along a single A–B traverse, with two scanning verticals (1T and 2T) sampled across the 4 km transect. Two distinct anomalies emerged on the same section.

Vertical 1T showed a continuous geothermal anomaly from surface down to 3 668 m — a single, deep, high-temperature target ideal for power generation via deep wells. Vertical 2T, just 800 m laterally, showed a completely different signature: a shallow horizon at 0–263 m followed by a thin deep layer at 3 534–3 654 m. The two verticals on one section reveal that the geothermal water flow geometry is asymmetric — a finding that conventional single-vertical methods would have missed entirely.

Depth profile · 1T vs 2T

Two verticals, two completely different geothermal signatures.

The 1T vertical shows the entire 0–3 668 m column as anomalous — suitable for a single deep well harvesting heat across the full depth range. The 2T vertical, in contrast, splits into a shallow 0–263 m horizon and a deep 3 534–3 654 m thin layer, with the rest of the column inert. Both verticals are part of the same resource, but each requires a different drilling strategy.

The two-vertical sampling reveals a fundamental asymmetry. A single-vertical survey would have characterised either the full deep column (1T) or the split-horizon profile (2T) — never both. The deep flow inferred at the base of 2T points toward a directional geothermal current, opening the possibility of tracking the source upstream.
Why this matters for geothermal. One survey, two extraction strategies. The 1T vertical supports a single deep well for binary-cycle power generation. The 2T vertical supports a shallow direct-use heat-exchange installation plus a deep injection target. Both can be developed in parallel on the same concession.
Case 02 · Oman 2018

Wahiba Desert — eight stacked aquifers, two scanning verticals

3.6 km baseline  ·  8 horizons V1  ·  7 horizons V2  ·  7 confirmed continuous  ·  580–1 100 ppm

In 2018, Inside Earth conducted a detailed vertical exploration in the Wahiba Desert. Two remote scanning verticals — V1 and V2 — were placed 3.6 km apart on the survey area, and at each one the full 0–300 m subsurface column was profiled for water content. The result was a stratigraphic map of unusual vertical resolution: eight aquifer horizons stacked from 77 m to 268 m.

Seven of those eight horizons appear at matching depths in V2, confirming lateral continuity across the survey area — these are sheet-like aquifers, not isolated lenses. Only one horizon (184–187 m at V1) had no V2 counterpart, identifying it as a local lens. The salinity gradient tells its own story: it falls steadily with depth from 1 100 ppm at the shallowest horizon to 580 ppm at the deepest — the deeper the resource, the fresher the water. V1 was issued as the recommended exploratory drill point.

Eight aquifer layers, mapped before a single drill bit turned.

The visualisation below shows the eight aquifer horizons recovered from the V1 vertical, projected across the survey area. Seven of the eight extend continuously to the V2 vertical 3.6 km away (rendered as full-area slabs); the 184–187 m lens, present only at V1, is shown as a localised body. Colour intensity encodes salinity: lighter celeste at the deepest, freshest layer (580 ppm), deepening to saturated blue at the shallowest, most saline layer (1 100 ppm).

Why this geometry matters. Eight aquifers in 200 m of vertical column — and seven of them confirmed continuous across a 3.6 km baseline — means the Wahiba subsurface holds far more accessible water than a single-vertical survey would have shown. The salinity gradient layered top-to-bottom from 1 100 ppm to 580 ppm reframes drilling economics entirely: the deepest target costs more per metre but delivers the cleanest water — a cost/quality trade-off that can be optimised before the rig moves.

Chernorechenskoye — aquifer geometry, then one well

32 km²  ·  depth investigated 3 000 m  ·  2 months  ·  aquifer 3 km × 300 m × 150 m thick

A regional water utility approached Inside Earth with a high-stakes question: was there sufficient potable groundwater under the Chernorechenskoye reservoir area to justify a deep production well, and if so — exactly where? A failed deep drill at this depth range would cost more than the entire remote survey.

Inside Earth executed a 32 km² remote geocosmic survey with photographic reconnaissance and spatial image interpretation. In two months, the team profiled an underground water anomaly with full geometry: limits, flow direction, total salinity, depth and thickness of the productive horizon. The recommendation specified a single drilling point with self-discharge guaranteed by aquifer pressure. Drilling at the recommended coordinates delivered 2 200 t/day of potable freshwater — confirming every parameter predicted from orbit.

The mechanism

"Boilers" — magma centres of extinct volcanoes that brew freshwater.

Inside Earth's groundwater theory rests on a recurring geological process: at extinct-volcano magma centres, seawater is drawn in at depth, evaporated, and the resulting steam migrates along faults until it cools and condenses into underground freshwater lakes. From those lakes, currents flow outward at depths of several hundred metres. The Chernorechenskoye aquifer is fed by one such mechanism — boiler N°2, in the Crimea peninsula.

"Boiler" cross-section · seawater intake → steam → freshwater current Vertical exaggeration ×2 · depths illustrative
mountain range Black Sea Magma chamber N°1 seawater intake steam · T = +100–200°C condensation FW lake · -930 to -1100 m freshwater current → production well 2 200 t/day 0 m -1 000 m -2 000 m -3 000 m
Seawater intake → freshwater current Steam phase / heat source Condensation zone Production well
Why the mechanism matters. Identifying the boiler that feeds an aquifer reframes the search. Instead of sweeping a region for water, we trace the freshwater back to its source — the magma centre — and forward to its discharge zone. That gives us depth, pressure, salinity and direction before any drilling commitment. Seventeen such boilers have been mapped to date across five continents.
Case 04 · Mongolia 2008

Gobi Desert — industrial well-field economics

345 km²  ·  3 months  ·  2 freshwater currents at 270–315 m  ·  2 confirmation drills

In 2008, Inside Earth conducted research and exploration for groundwater across 345 km² of the Gobi Desert in Mongolia. The remote phase took three months. Two underground freshwater currents were discovered at depths of 270 to 315 m, with a horizon thickness of 45 m and current widths between 4 and 5 km, covering most of survey areas N°2 and N°3. Survey area N°1 returned no significant flow — and was excluded from drilling.

Two exploration wells were then drilled only on the confirmed currents. They returned the predicted flow rates — 0.6 m³/s and 1.6 m³/s respectively. The economic projection that followed: 25 industrial wells of 200–270 mm diameter would deliver 1.5 billion litres of water per year, equivalent to the annual consumption of two million people. Zero capital wasted on dry zones.

Decision economics

The remote map turned three uncertain sectors into one drilling plan with two confirmation holes.

In conventional exploration, all three sectors would have received scout drilling. With Inside Earth's prediction, only the two anomaly zones were drilled — and both confirmed at the predicted flow rate. The dry sector was identified from orbit, before any equipment moved.

Drilling discipline

Two confirmation wells drilled out of three candidate sectors — one third of the survey area never required a single drill metre.

Flow accuracy
100%

Both confirmation wells returned the predicted flow rates (0.6 and 1.6 m³/s) within the documented confidence interval.

The 25-well field projection — a function of confirmed current geometry, not optimistic extrapolation — delivers two million people-equivalent per year.

Case 05 · Mauritania 2001

Sahara Desert — Ministry of Energy of Mauritania

Geology Department commission  ·  Chief Geologist Ibrahim Lamine  ·  1 600 km²  ·  commercial flow at 75 m

In 2001, the Geology Department of Mauritania's Ministry of Energy commissioned the search for natural freshwater deposits across a sector of the Sahara Desert. The challenge: arid surface, no infrastructure, no roads, no prior geological reference — a 1 600 km² block to be characterised remotely before any field equipment moved.

Inside Earth deployed remote sensing methods over the entire area, then validated parameters at selected anomaly points using field NMR equipment. The combination confirmed groundwater currents and pinpointed extraction coordinates. A commercial flow at 75 m depth, extending to 150 m, was discovered and delivered to the client at 900 tonnes per hour — meeting drinking water standards.

The desert challenge

How do you find drinking water under 1 600 km² of sand without a roadmap?

The challenge

The Sahara at this latitude offers no surface clues. There are no streams, no vegetation belts, no obvious recharge zones. Conventional groundwater exploration would have required years of seismic-then-drilling iteration, with most boreholes returning saline water or dry. The economic and environmental cost of that approach made the entire programme unviable.

The Ministry of Energy needed something different: a method that could cover the full 1 600 km² in months, not years, and deliver coordinates with enough confidence to drill once and drill right.

The Inside Earth approach

The workflow combined two phases that share no equipment with traditional hydrogeology. Phase I — remote sensing: multi-band satellite imagery processed through proprietary spectral plates and patented gel filters revealed the atomic signature of subterranean water across the full block.

Phase II — field NMR validation: at the anomaly points identified from orbit, ground-based NMR equipment measured depth, thickness and flow direction. The recommendation issued to the Ministry contained the exact drilling coordinates and the predicted discharge rate of 900 t/h. Drilling confirmed the prediction.

Outcome. One commercial freshwater flow, 1 600 km² characterised, zero exploratory dry holes — and a body of water large enough to supply the daily consumption of 11 million people, all from a region historically classified as non-productive.
The boiler atlas

Seventeen magma centres, five continents, one mechanism.

Inside Earth has mapped seventeen extinct-volcano magma chambers ("boilers") that generate underground freshwater and geothermal currents. Each confirmed boiler explains the freshwater inventory of a wide territory — and points to the optimal extraction zones along the discharge currents.

Technology workflow

From orbit to drilling coordinates in four stages.

The Inside Earth pipeline has the same four stages whether the target is freshwater, geothermal, hydrocarbons or minerals. What changes is the atomic reference loaded into the patented gel filter — water, hydrogen sulfide, a noble gas, a metal. The signal physics stays constant.

Stage 01 · ERS I
Satellite imagery

Far IR · UV · microwave · visible.

Ultra-high-resolution imagery from various satellites, received at the UNISCAN-24 ground station. Processed for spectral reflectance, anomaly identification and tectonic-fault tracing across the survey area.

Stage 02 · Spectral
Atomic spectra transformation

Special plates + patented gel filter.

The processed satellite images pass through proprietary plates and a gel filter loaded with the atomic reference of the compound of interest — water in this case. The output is a first-order map of the target's spectral signature.

Stage 03 · NMR
Amplification & NMR in laboratories

IR-100 reactor · gamma-energy irradiation.

Nuclear magnetic resonance combined with amplification of electromagnetic signals from the imagery. The patented technique determines the location, depth, thickness and quality of the targeted atomic element with up to 7 500 m of subsurface resolution.

Stage 04 · Deliverable
Business data & decision maps

Decision-grade maps and dashboards.

Synthesised, georeferenced reports tailored to client needs: aquifer contours, well coordinates, salinity classification, current direction, horizon thickness and recommended drilling depth — everything required for a single confirmation drill.
