Gravity Survey

At Retro Geoenergy, we provide precise Gravity Survey Services to support mineral, oil & gas, groundwater, and geotechnical exploration projects. Gravity surveys measure subtle variations in the Earth’s gravitational field caused by density contrasts in subsurface rocks, enabling accurate mapping of geological structures, resource bodies, and basin architecture.

By combining advanced gravimeters, GPS-based positioning, and modern data processing techniques, we deliver high-resolution gravity data tailored to exploration and engineering needs.

• Mineral Exploration
– Detecting ore bodies, coal seams, bauxite, and dense mineral deposits.
– Mapping structural controls associated with mineralization.

• Oil & Gas Exploration
– Delineation of sedimentary basins and basement configuration.
– Identifying structural highs, traps, and fault systems.

• Groundwater & Hydrogeology
– Mapping aquifer geometry and basement depth.
– Identifying subsurface fractures and structural controls influencing groundwater flow.

• Geotechnical & Engineering Studies
– Bedrock depth estimation for dams, tunnels, and infrastructure projects.
– Detecting voids, sinkholes, and subsurface anomalies.

• Regional & Environmental Studies
– Mapping tectonic features and regional crustal structures.
– Supporting earthquake and geohazard assessments.

• Ground Gravity Surveys (conventional & high-resolution)

• Microgravity Surveys for shallow subsurface anomaly detection

• Gravity Gradiometry (high-precision density contrast mapping)

• Gravity Data Processing & Interpretation:
    – Bouguer, terrain, and drift corrections
    – Regional–residual separation
