Assets in the oil and gas industry include all physical infrastructure and equipment in the production area, such as buildings, roads and heavy equipment.
Assets monitoring is required during operations to mitigate various kinds of risks throughout the project lifecycle to ensure the safety of employees and property. Monitoring systems can be supported and enhanced with EO techniques.
Information derived from EO data can contribute to a better understanding of an exploration or development area and supports decision-making. Both optical and radar datasets can contribute to asset monitoring, with high resolution EO data typically required.
Near real-time image delivery is available, which may be important for monitoring. Daily revisit is available for very high resolution optical data, e.g. RapidEye and Pleiades, and 2-3 days for future Sentinel-2 for many areas. Very high resolution radar can help to mitigate cloud cover issues, and InSAR techniques support specialised asset monitoring in areas susceptible to land deformation.
Asset monitoring can include a suite of products and services:
The asset monitoring product delivers spatial vector information about the position and type of assets detected, noting potential factors of concern, such as encroachment, flood risk or deformation.
Known restrictions / limitations
Lifecycle stage and demand
Pre-license: No use.
Exploration: Reduces risks in development planning. Safer access for exploration and evaluation.
Development/Production: Improvement of construction and operation safety. Monitoring of asset condition. Monitoring of potential encroachment or damage by communities or environment.
Decommissioning: Reclamation monitoring.
Geographic coverage and demand
Demand is global, but focused on locations with unstable environmental or social conditions.

OTM:024 Encroachment on O&G assets
OTM:040 Security of pipelines
OTM:065 Floodplain mapping
HC:2102 Understanding hydrogeology
Input data sources
For assets mapping:
Optical: VHR1, VHR2, HR1, HR2, MR2
For waterbodies and land /environment properties:
Optical: HR1, HR2, MR1
Radar: HR2, MR1
For surface disturbances:
Radar: VHR2, HR1, HR2 for InSAR analysis
Supporting data: Existing GIS data such as hydrological networks, topographic maps, infrastructure, and assets
Spatial resolution and coverage
For assets monitoring very detailed resolution is needed: 5 m or better.
Flooding and the surrounding environment can be monitored with less detail using data with spatial resolution from 5 to 30 m.
Minimum Mapping Unit (MMU)
Variable, depending on features being monitored. Assets as small as roughly 4 m2 can be detected.
Accuracy / constraints
Thematic accuracy: Depends on the parameter and sensor used for its calculation.
Spatial accuracy: As determined from component products.
Accuracy assessment approach & quality control measures
Comparison with in-situ measurements.
Frequency / timeliness
Observation frequency: Dependent on the sensor, but daily update is possible. Frequency of historical maps is highly variable depending on the archive.
Timeliness of delivery: Processing can be completed in near real time (< 24 hours).
On-demand availability from commercial suppliers.
Some HR2 and MR1 products are freely available for public search.
