GLOBAL REACH
SJ Geophysics has international work experience. We have acquired geophysical surveys in over 50 countries, on 6 continents, and with more than 700 clients, amounting to over 2000 projects. Our flexibility has allowed us to perform field jobs in vastly different areas of challenging terrain such as frozen tundra, equatorial jungles and desert areas. Our field crews have the ability and experience to adapt to any type of terrain. The global reach translates into the fact that we have experience with many different types of resource deposits; including mineral deposits (disseminated to massive sulfides, porphyry, sedex, uranium, etc.), precious stone deposits (diamond), industrial minerals (gravels), and ground water.

Magnetotelluric surveys are an unique electromagnetic technique that utilizes natural energy as its source. Measurement in the variation of these natural magnetic B(t) and electrical E(t) fields can be used to derive the electrical properties of the subsurface material.
Gravity surveys are a passive potential field method that measures variations in the earth’s gravitational field. These variations are the result of changes in the subsurface density distribution of rocks and minerals. Gravity data requires careful data reduction procedures to remove influencing factors such as the earth’s ellipticity, lunar tidal forces and local geographic effects. After corrections have been made, subtle features can be identified in the data.
