01 · LOCATE
Determine pipeline position.
Improve understanding of the buried steel pipeline alignment and route continuity.
PHASE 1 · UAV AEROMAGNETIC PIPELINE CORRIDOR SURVEY
Establish the physical reality of the corridor.
A non-contact field program to improve pipeline localization, screen magnetic anomalies, prioritize direct verification and establish the baseline for future monitoring.

02DefineIdentify segments and joint features
03ScreenPrioritize areas of interest
Why Phase 1
Start with corridor reality before designing the larger system.
Swamps, flooded areas, deep snow, vegetation and difficult terrain can interrupt conventional field programs. Historic route information may also be incomplete or no longer match present conditions.
02 · DEFINE
Identify segments and joints.
Map magnetic features associated with pipe sections, joint locations and weld areas.
03 · SCREEN
Prioritize areas of interest.
Identify magnetic signatures and changes that may justify targeted ground verification.
WHAT THE METHOD SUPPORTS
Corridor localization, anomaly screening, route and segment intelligence, comparison between controlled surveys and prioritization of follow-up locations.
ENGINEERING BOUNDARY
A magnetic anomaly is not automatically a confirmed defect. Defect classification and sizing require appropriate field correlation and operator-approved engineering methods.
Phase 1 Workflow
Scope. Acquire. Process. Verify. Decide.
Every work package begins with the operator's records and decision needs, then builds evidence through controlled acquisition and selected verification.
Define the corridor
Review alignment records, construction data, known features, access limits and integrity questions.
Survey the corridor
Collect repeatable UAV magnetic data and reference measurements under documented conditions.
Build the evidence
Apply quality control, correction, georeferencing, mapping and anomaly interpretation.
Correlate selected locations
Compare observations with operator records and appropriate targeted field checks.
Prioritize action
Deliver a ranked verification plan and recommendations for the next integrity step.
Survey System
Two magnetic measurements. One controlled survey workflow.
The payload and reference measurements are configured around the corridor, terrain, safety and repeatability requirements of the work package.
UNMANNED AERIAL VEHICLE
Controlled corridor acquisition.
Carries the survey payload along flight lines configured for terrain, safety and repeatability.
THREE-COMPONENT FERROSONDE MAGNETOMETER
Directional magnetic response.
Measures X, Y and Z magnetic-field components and captures directional changes in pipeline response.
POS PROTON MAGNETOMETER
Absolute scalar-field reference.
Provides an absolute scalar-field reference for background and consistency checks.
RAVAM PROCESSING & GIS
From field measurements to operator-ready evidence.
Supports quality control, transformation, anomaly localization and operator-ready reporting.
Controlled Evidence
Welds, joints and introduced changes produce measurable magnetic response.
The supplied controlled test data demonstrate measurable magnetic signatures and changes. They support screening methodology development; they do not by themselves establish field defect classification.
The controlled configuration shows pronounced response around pipe-joint features.
The supplied test reports a reduced anomaly amplitude after the pipe segments were welded.
The proton magnetometer serves a different measurement role in the controlled survey system.
Interpretation boundary: changes in amplitude, extrema and local minima can support anomaly screening. The response is not, by itself, a field defect classification.
Field Correlation
Repeatability depends on survey control.
Every campaign documents the conditions that influence magnetic data so later surveys can be compared on a consistent basis.
