What is ddt?
A proprietary geophysical methodology
DDT™ is a proprietary geophysical methodology developed to detect and delineate subsurface hydrocarbon accumulations.
The technology is based on OGD's interpretation of naturally and occurring intrinsic radiation associated with matter in the Earth's crust. DDT converts latent mineral-correlated signatures recorded in the silver-halide emulsion of analog satellite imagery into detectable and spatially recovered evidence of target mineralization. According to the DDT™ scientific model, physical materials in an excited state — driven by the influence of Earth's geophysical fields — generate distinctive energy signatures associated with Super Small Subatomic Particles (3SP) and their corresponding radiation phenomena.
OGD's laboratory and field systems are designed to analyze the measurable effects associated with these phenomena—including characteristic reflections, shadows, tracks, frequencies, amplitudes, and phase relationships.
Different elements and compounds are interpreted as producing distinctive intrinsic radiation spectra. These signatures form cluster and macro-cluster field structures that can be analyzed to identify variations within subsurface formations and evaluate the possible presence and distribution of hydrocarbons.

ddt & conventional exploration
How DDT™ complements conventional exploration
Traditional hydrocarbon exploration commonly involves a sequence of geological, geochemical, geophysical, and drilling activities, including:
Geological mapping and regional evaluation

Field reconnaissance, aerial photography, and satellite analysis
Geochemical sampling of soils, sediments, and other materials
Gravity, magnetic, resistivity, and 2D/3D seismic surveys
Exploratory drilling, well logging, testing, and reservoir evaluation
These methods remain important components of petroleum exploration, but they can require significant capital, extensive field operations, and long project timelines.
DDT™ is designed to complement and potentially reduce the scope of conventional exploration by identifying and prioritizing prospective areas before companies commit to more expensive seismic programs or exploratory drilling.
The DDT™ Survey Process
Satellite reconnaissance, imagery collected, then airborne field survey
Each stage narrows the search area — from a broad territory to a small, graded target zone
Reconnaissance study
Star One
Prospective district · Yellow contour
The first stage uses OGD's proprietary Star One, Star Two and Stage One Surveys to evaluate large geographic areas from satellite data. Star One is designed as a large-area reconnaissance program, typically covering approximately 5,000–100,000 km² and more, depending on the geological setting, exploration objectives, accessibility, and operational environment. Its primary objective is to establish whether geophysical signatures consistent with the targeted mineralization are present within the surveyed territory or offshore area.
The process includes:
-
Analysis of satellite imagery using proprietary processing techniques
-
Identification of anomalous signatures associated with target resources
-
Preliminary evaluation of the presence or absence of prospective hydrocarbon zones
-
Definition of the general geographic boundaries of identified anomalies
-
Selection and prioritization of areas for detailed Stage Two investigation
A reconnaissance area of approximately 100 km × 100 km can typically be evaluated within approximately 4-5 weeks, depending on project requirements and data availability.
Enlarged study of the prospective district
Star Two
Prospective area · Green contour
Star Two focuses on the prospective areas identified during Star One. Enlarged primary anomalies associated with the target mineral’s own radiation are recorded and ranked by significance. Based on the distribution and relative strength of these anomalies, enlarged prospective areas are delineated, providing a more precise basis for geological interpretation and subsequent target grading and exploration.
Detailed study of the enlarged prospective area
Stage One
Prospective area · Blue contour
Stage One focuses on identifying primary anomalies associated with the target mineral’s own radiation. The detected anomalies are recorded and ranked by significance, allowing prospective areas to be delineated for further analysis and more detailed investigation in subsequent survey stages.
Airborne Field Survey
Stage Two
Prospective area · Blue contour
Priority areas identified during satellite reconnaissance can be investigated using helicopter or low-altitude aircraft equipped with OGD's GEO-SCAN ML3 and MLS-3 survey system. The system incorporates specialized mono-spectrometers calibrated for selected elements and compounds. There are two models of DDT field equipment: for airborne survey and compact back pack model. DDT field equipment set is portable and may be installed on ATW, helicopter, low speed boats or planes. Compact model may be packed as a backpack and carried by person.
Stage Two surveys are designed to generate high-resolution digital interpretations showing:
-
Intrinsic radiation intensity
-
Geographic extent of interpreted hydrocarbon accumulations
-
Prospective drilling locations
-
Estimated depth and thickness relationships
-
Spatial distribution of targeted subsurface formations
Survey results can be presented as color-coded maps, topographic overlays, cross-sections, and 3D block diagrams to support geological interpretation and drilling decisions.
Direct detection vs. indirect methodologies
DDT vs. today's exploration technologies
DDT is different because it is designed to detect the resource signature itself — not only the surrounding geological clues
Technology | What It Mainly Detects | Key Limitation | DDT Advantage |
|---|---|---|---|
Magnetics and Gravity | Physical-property contrasts | Shows structures and anomalies, not certainty of mineral type | DDT focuses on target identification |
Satellite / hyperspectral | Surface mineral indicators | Mostly surface or alteration mapping | DDT aims beyond surface indicators |
Geochemistry / Сore / CC | Physical samples and lab analysis | Slow, local, expensive, late-stage | DDT can screen large areas faster |
Electromagnetic Surveys | Conductivity and resistivity contrasts | Strong for conductive bodies, weaker for non-conductive targets; sensitive to noise, metal objects and soil conditions | DDT is less sensitive to EM interference |
AI Prediction (KoBold) | AI prediction from existing geological data | Depends on data quality and model assumptions | DDT generates direct detection intelligence |
Muon Tomography (Ideon) | Subsurface density using muon tomography | Requires local deployment; detects density anomalies, not resource identity | DDT targets resource-specific signatures |
