GEOPHYSICAL STUDY

PT Terra Nusa Prima provides comprehensive Geophysical Study services to support mining exploration, groundwater investigation, environmental assessment, civil engineering design, and near-surface subsurface interpretation. Combining modern geophysical equipment and advanced data processing techniques, we deliver accurate imaging of underground conditions without the need for extensive drilling.

GEOPHYSICAL STUDY

🌐 Geophysical Study: Accurate and non-destructive subsurface investigation services. 🔹 Electrical Resistivity Tomography (ERT) for groundwater and geological assessment. 🔹 Seismic Refraction to determine soil and rock layering. 🔹 Ground Penetrating Radar (GPR) for shallow imaging and infrastructure inspections. 🔹 Magnetic Survey for detecting geological structures and mineral anomalies. 🔹 Electromagnetic (EM) Survey for rapid geological and groundwater reconnaissance. 🔹 Supporting mining, environmental, groundwater, and construction projects with accurate data.

Our studies help engineers, planners, and developers make informed decisions by understanding soil, rock, groundwater, and geological structures before construction or development begins.

Scope of Services

Electrical Resistivity Tomography (ERT)	ERT is one of our most widely used methods for: Groundwater exploration Mapping subsurface stratigraphy Detecting faults, cavities, and fractures Contamination assessment Engineering site characterization 2D and 3D interpretations provide a reliable representation of subsurface resistivity patterns.
Seismic Refraction	Seismic refraction is used to evaluate: Soil and rock layering Engineering soil properties Rock depth and weathering profiles Rippability analysis for mining and construction This method is essential for foundation planning and excavation projects.
Ground Penetrating Radar (GPR)	GPR is effective for shallow investigations such as: Mapping buried utilities Archaeological surveys Pavement assessment Infrastructure inspection Shallow soil and void detection GPR delivers fast, high-resolution subsurface imaging with minimal disturbance.
Magnetic Survey	Magnetic surveys are performed to identify variations in the Earth’s magnetic field, helping to: Detect mineral deposits Map geological structures Locate buried metallic objects and anomalies Support exploration programs This method is efficient and widely used in early-stage exploration.
Electromagnetic (EM) Survey	EM surveys are useful for: Groundwater detection Soil conductivity measurement Mineral exploration Contamination plume mapping Low-impact geological reconnaissance EM tools provide large-area coverage with high data acquisition speed.

Why Geophysical Studies Are Important
