Hilly terrain where surface conditions had to be read together with mining works
The project covered the Siliștea–Măgureni field in Prahova County, about 30 km from Ploiești: 7.4 km² of hilly terrain ranging from 334 m to 457 m above sea level.
At the time of the published project, the area overlapped the activities of four mining companies and six active mining licences. This is retained as historical project context, not as a statement about their current status.
A realistic 3D model for risks and obstacles that were difficult to see from the ground
The aim was to create a visual and measurable basis for deeper study of logistical, environmental, safety and commercial issues associated with hydrocarbon development beneath a mining-affected area.
The surface model and maps were intended to reveal mining impacts, obstacles hidden from ground inspection and constraints relevant to the technical and HSE understanding of a possible Fora Oil and Gas operation.
- realistic understanding of terrain and site access;
- identification of mining works and areas that could affect planning;
- clear communication of technical, environmental and HSE constraints;
- visual support for well-location and logistics options.
Information prepared for montage and overlay
The orthophoto and 3D model supported overlays that connected visible conditions with available technical information.
- mining areas and open pits, whether active or abandoned;
- spoil heaps, waste material and other mining traces;
- underground mine galleries;
- preferred well locations;
- the estimated subsurface outline of the hydrocarbon-saturated area.
The mapping and 3D package envisaged by the study
The provisional scope started with a UAV photogrammetric mosaic and allowed alternative survey products or services to be assessed where technically useful.
- 1. Digital terrain maps
- Topographic mapping with contour representation.
- 2. Gallery-overlay maps
- Digital maps overlaid on the underground mine-gallery plan.
- 3. 3D surface model
- Three-dimensional reconstruction of terrain and visible features.
- 4. 3D model with wells
- Surface model completed with the well positions listed in annex 2.
- 5. Digital elevation model
- Raster product for analysing levels and terrain variation.
- 6. Spatial-planning data
- Layers prepared for site and constraint analysis.
- 7. Oblique aerial imagery
- Additional perspectives for interpreting objects and slopes.
- 8. Orthophotos
- Rectified, georeferenced aerial imagery for mapping.
The seven technical plates from the original study
All seven plates remain uncropped and are grouped by the technical question they help answer.
Terrain and project boundary
The elevation model and orthophoto establish the landform and exact area before thematic overlays are added.
Mining context and well positions
These sheets connect visible conditions, mining features and proposed well positions for constraint analysis.
Topographic sheets and terrain profile
The final products bring contours, land use and the longitudinal profile into views prepared for technical review.
