Gravity has been used successfully to monitor water influx in gas fields. Subsidence can give valuable reservoir information for both oil and gas fields.
Gravity monitoring has been reported from at least 26 geothermal sites around the world, successfully measuring the water recharge and sustainability of the process.
Gravity measures changes in the aquifers. It is useful for monitoring the sustainability of water supply and utilisation.
Gravity can detect magma flow and predict eruptions.
Monitor the distribution of injected CO2 or hydrocarbon gas in a storage reservoir. Detect any leaks.
Small changes that are precursors or mapping of risks for hazardous events.
Knowledge on the near-surface is used for civil engineering purposes. Features may be natural or man-made.
High-density minerals and associated material often cause gravity anomalies.
Microgravity can determine architectural remains, caves, voids, crypts and buried thumbs.
