All survey mentioned above designed in an integrative framework to obtain a comprehensive picture of subsurface condition. Gravity & Magnetics Surveys SGCO provides Land, Marine & Airborne gravity & magnetics survey for oil and gas as well as for mineral prospecting. Our service starts from design, data acquisition, processing and interpretation LaCoste & Romberg Model-G gravity meter & ZLS dynamic gravity meter are used for gravity while Geometric Magnetometer is used for Magnetics.
