High Resolution Airborne Geophysics

Petroleum Services

Airborne geophysical surveys are conducted worldwide for oil and gas exploration, both offshore and onshore. Traditional methods include potential field mapping of exploration blocks (magnetics and gravity), however there are also applications for electromagnetics in onshore exploration. UTS Geophysics owned and operated GT-1A gravimeter and purpose built PAC 750 fixed wing aircraft offer exceptional gravity data of particular use to the petroleum industry.

Offshore Surveys

Offshore gravity and magnetic surveys can reveal valuable geological information within exploration blocks and can complement existing or planned seismic data. Volcanics, faults, basin boundaries and sub-basin features can be mapped with these methods. Of particular use for oil & gas exploration is the ability to map geological structures in transition zones and shallow water areas, where seismic vessels cannot navigate.

UTS Geophysics utilises aircraft that are specifically setup for offshore operations, with additional emphasis on safety precautions, including long-range tanks and survival equipment.

Onshore Surveys

In addition to the geophysical techniques applicable for offshore surveys, as mentioned above, onshore petroleum exploration can also benefit from airborne electromagnetic surveys. This technique identifies conductivity contrasts to depths of several hundred metres and can be used for detailed paleochannel mapping and statics corrections of seismic data.
