Output & Deliverables
Ranked Prospects. Ready for Decision-Making.
Every SFD® survey concludes with a formal Recommendations Report — actionable deliverables designed for immediate use in exploration decision-making. Here’s exactly what you receive and how to interpret it.
Recommendations Report
Image placeholder: an SFD® Recommendations Report with sample sensor response curves, anomaly maps, and ranked prospect leads. Use approved report material; do not invent survey results.
Survey Deliverables
What You Receive
SFD® survey deliverables are designed to integrate directly into your existing G&G workflows. Each survey produces:
01
Annotated sensor response curves
For each flight line — the raw interpreted signal data showing where anomalies were identified along each transect
02
Anomaly maps
Combining interpretation across all sensors and lines — a spatial overview of every identified anomaly and its extent
03
Dual-ranked prospect leads
Each lead area is assigned both a trap quality score and a reservoir quality grade (see ranking system below)
04
Integrated prospectivity map
With hot-to-cold colour grading showing the spatial extent and assessed quality of all identified leads across the survey area
SFD® Ranking System
How Prospects Are Ranked
Each recommended SFD® lead area is assigned a number to denote trap quality and a letter to denote fluid presence indicators. This dual ranking gives your G&G team a clear, standardised framework for prioritising follow-up work.
Trap Indicators
| Score | Assessment |
|---|---|
| 1 | Fair trap potential |
| 1+ | Good trap potential |
| 2 | Very good trap potential |
| 2+ | Excellent trap potential |
Reservoir Indicators
| Grade | Assessment |
|---|---|
| C | No reservoir potential indicated |
| C+ | Poor reservoir potential |
| B- | Minor reservoir potential |
| B | Moderate reservoir potential |
| B+ | Good reservoir potential |
| A | Very good reservoir potential |
| A+ | Excellent reservoir potential |
Prospectivity Map
Map placeholder: an approved survey-area prospectivity map with hot-to-cold colour grading. Include a readable legend explaining the scoring system and clear annotations of ranked lead areas.
Prospectivity Mapping
From Rankings to Maps
Where surveys are performed in a regular grid pattern (line spacings vary by programme, commonly in the range of 5–10 km) or quasi-grid pattern, the results are represented as a prospectivity map. The qualitative SFD® ranking is further quantified using a scoring system to create a prospectivity grid with hot colours indicating higher quality lead areas versus cold colours showing lower assessed prospectivity.
SFD® Signal Characteristics
Understanding the SFD® Signal
NXT’s Citation 560 jet carries numerous individual SFD® sensor elements, each generating its own unique output signal captured as a digital time series.
The signal is akin to a waveform, with the horizontal axis measuring flight time (seconds) and the vertical axis a voltage output (V). Time readings correspond to a unique GPS-based surface location and are plotted as a flight line over the survey area.
The signal is a non-linear, discrete-time representation of each sensor’s output voltage, acquired at up to 2,000 samples per second depending on programme configuration.
