The determination of mass distribution in the sub-surface holds significant importance in natural resource exploration campaigns and civil engineering development. Gravity measurements serve as indicators of rock density, making them invaluable exploration tools. For instance, high mass anomalies may signify ore bodies, while low mass anomalies could indicate salt domes, and linear anomalies may suggest fracture zones or dikes.
The gravity method was the first geophysical technique to be used in oil and gas exploration. Despite being eclipsed by seismology, it has continued to be an important and sometimes crucial constraint in a number of exploration areas. In oil exploration the gravity method is particularly applicable in salt provinces, overthrust and foothills belts, underexplored basins, and targets of interest that underlie high-velocity zones.
EGSE, in collaboration with its shareholder ENERSON, operates a specialized gravity division. Our crews, comprising geophysicists, technicians, and geodesy experts, swiftly navigate large areas, obtaining precise gravity readings alongside high-accuracy altitude and location measurements.
Whether conducting regional or local micro-gravity surveys, standalone or as support for a seismic campaign, EGSE stands ready to provide tailored solutions. Our full suite of services includes:
- Survey design
- Acquisition
- Processing
- Integration and interpretation with seismic, magnetic, EM, and other geological data
We recognize that precise anomaly detection forms the foundation for successful exploration campaigns.
