Upstream & midstream support
Oil & Gas
From undeveloped sites to congested brownfield facilities, SEC converts field measurement into engineering data for oil and gas projects — positioning, mapping, subsurface and geotechnical.
Sector challenges
The ground problems energy projects inherit
Brownfield uncertainty
Live facilities where existing drawings no longer match the ground and buried lines are not where records say they are.
Remote and dispersed assets
Well pads, flowlines and facilities far from established survey control, yet all required to sit on one coordinate framework.
Multi-contractor coordination
Several EPC and construction contractors working simultaneously — each needing the same control, the same datum and the same spatial data.
Excavation near live networks
Ground work beside energized cables and pressurized lines, where assumption is not an acceptable safety basis.
Project lifecycle
From site intelligence to as-built record
SEC supports the asset lifecycle as one continuous measurement chain — every later stage inherits the control and data of the one before it.
01
Planning & site intelligence
Baseline mapping and spatial data compilation for site selection, layout studies and permitting support.
02
Survey control & positioning
Project control networks and GNSS positioning tied to the network, providing a common framework for contractor measurement.
- CORS Network & RTK Services
- Control Networks & Benchmarks
- GNSS / RTK Survey
03
Topographic survey
Existing-surface capture of pads, plants and corridors as the design basis.
- Surveying & Geomatics
- Topographic Survey
04
UAV & LiDAR acquisition
Airborne photogrammetry and LiDAR for large or hard-to-access areas — orthomosaics, terrain models and point clouds.
05
Subsurface & utility detection
Underground service survey before trenching, piling or tie-in work.
06
Geotechnical investigation
Field investigation, laboratory testing and reporting for foundation and earthworks design.
07
GIS & spatial data management
Survey, utility and facility data structured into GIS layers the whole project team can query.
08
Construction survey support
Setting-out, verification and survey crews supporting construction through execution.
- Construction Survey
- Surveying & Geomatics
09
Reality capture & as-built
Laser scanning and as-built survey closing the loop — the asset as actually built, documented for operations and future modification.
- LiDAR & Reality Capture
- Engineering Survey
Technology approach
One positioning backbone, many sensors
Network positioning
CORS-based GNSS correction references dispersed crews and corridor works to a shared reference frame.
Airborne & terrestrial capture
UAV photogrammetry, aerial LiDAR and terrestrial laser scanning selected per site — congested plant or open desert corridor.
From field data to engineering data
Acquisition, positioning, processing and QA flow into deliverables for engineering teams — drawings, models, GIS layers and reports.
Field equipment
DJI
DJI Matrice 300 RTK
A UAV platform of the type used to carry survey and inspection payloads, within the scope agreed for the project.
CHCNAV
CHCNAV i83 GNSS
A multi-constellation GNSS receiver used for field survey work referenced to the project frame.
Radiodetection
Radiodetection RD8200
A cable and pipe locator used within subsurface utility survey scopes.
