Geophysical Surveys in Indonesia
Geophysical surveys read subsurface conditions without digging — to find groundwater, assess ground for construction, search for minerals, and detect buried objects. Jatific supplies geophysical survey instruments from world brands (Geometrics, OYO, IRIS) with local technical support.
What is a geophysical survey?
A geophysical survey measures the Earth's physical properties — such as electrical resistivity, seismic velocity, magnetic field, or water resonance — from the surface to infer what lies below. Each method excels for different targets, so choosing the right method and instrument determines both accuracy and cost-efficiency.
Choose a solution by need
Every need has a best-fit method and instrument. Here are the geophysical survey solutions most searched for in Indonesia:
Find Groundwater
Locate aquifers before drilling — resistivity for mapping, NMR (NUMIS) for direct water detection.
Learn moreResistivity / Geoelectric
1D/2D/3D subsurface mapping for groundwater, geotechnics, and minerals.
Learn moreVs30 & Site Class (SNI 1726)
Measure shear-wave velocity for earthquake-resistant design and microzonation.
Learn moreDrone Magnetic Survey
Map magnetic anomalies from the air — fast, reaching difficult terrain.

Why Jatific
Frequently Asked Questions
- What are the geophysical survey methods?
- Common ones in Indonesia: resistivity/geoelectric (groundwater, geotechnics), seismic refraction & MASW (ground structure, Vs30), magnetics (structures & buried objects), IP/induced polarization (minerals), NMR (direct water detection), and borehole logging. Each method excels for a different target.
- Which method finds groundwater?
- Resistivity (geoelectric) to map aquifer layers, and NMR/NUMIS to detect the presence of water directly. The two can be combined so drilling is better targeted.
- Which method for Vs30 and earthquake-resistant design?
- Suspension PS logging (McSEIS-PS) in a borehole for accurate Vs/Vs30, or MASW/microtremor for a surface approach — meeting SNI 1726 and microzonation needs.
- Does Jatific sell instruments or survey services?
- Jatific supplies geophysical survey INSTRUMENTS along with training, calibration, and technical support. Our instruments are used by many consultants and institutions to carry out surveys in Indonesia.
- Which brands are available?
- Geometrics (USA), OYO (Japan), and IRIS Instruments (France) — three leading geophysical instrument makers, with several products practically available only through Jatific in Indonesia.
