Aeromagnetic Survey Data for Offshore Petroleum Exploration

British Geological Survey provides over 22,000 km of corrected aeromagnetic total intensity data from offshore petroleum areas. The data assists directional drilling, with line separation of 2 km and flight altitude of 80 m above sea level. Some surveys are exclusive to BGS, while others require permission from the survey company.

Use Cases

• Model subsurface geology using corrected aeromagnetic total intensity data for petroleum exploration
• Analyze magnetic field anomalies along 22,000 km of survey lines to identify drilling targets
• Integrate GPS-navigated flight path data with magnetic intensity for spatial analysis of offshore basins

Strengths

• Over 22,000 km of corrected aeromagnetic survey data provides significant spatial coverage
• Standardized collection parameters include 2 km line separation and 80 m flight altitude
• Data sourced from the authoritative British Geological Survey

Limitations

• Data scope is limited to offshore petroleum areas, not representative of other geological settings
• Access restrictions vary, requiring permission checks for some exclusive surveys
