Geophysical surveys provide a baseline of spatial data for a variety of industries. The data collected can include such things as rock formations, soil morphology and landforms. Seismic profiling and ground penetrating radar are used along with a wide array of other remote sensing tools to survey specific areas. Such surveys can be used for mineral and archeological explorations, construction and urban planning.

The tools used to conduct geophysical surveys tend to be expensive and require extensive expertise to operate. Many firms that provide geophysical surveys offer data collection and analysis services as well. The data collected from geophysical surveys is used to create data layers and maps using geographic information systems software.

1. Hire a reputable company with a proven track record to create geophysical surveys of crucial properties.

2. Run the data from geophysical surveys through mapping software to create data layers and graphic representations of the region.

3. Document mineral resources for extraction with geophysical surveys.

Action Steps
The best contacts and resources to help you get it done

Hire an experienced international firm for geophysical surveys

When operating in foreign countries, it is prudent to have an experienced local contact, and this is especially true when conducting geophysical surveys. Difficult terrain and complicated regional regulations are more easily navigated by a local who is familiar with personnel and suppliers. Operating in remote regions requires logistical support, and an experienced firm can smooth the way.

I recommend: Global Geophysical Services can provide both terrestrial and aquatic geophysical surveys. The firm has extensive international experience and has a large number of employees worldwide. WesternGeco is a global leader in geophysical surveys.

Use ground penetrating radar to conduct geophysical surveys

Ground penetrating radar is one of the most common pieces of equipment for conducting geophysical surveys. The radar is dragged across the ground and images of the subterranean landscape can be collected. The radar images can reveal a variety of hidden structures, such as lost graves or buried tanks and it is especially useful in geological mapping.

I recommend: GeoModel specializes in a variety of ground penetrating radar applications. They have used ground penetrating radar for geophysical surveys across America and in several foreign countries. Radarscan employs ground penetrating radar in a variety of areas including oil and gas, utility location and agriculture.

Employ aerial data acquisition for geophysical surveys of difficult terrain

Most new mineral deposits are discovered in remote areas of the world. Mineral exploration often starts with the initial geophysical surveys conducted from the air. Remote sensing equipment is used to identify likely sites for further exploration.

I recommend: Terraquest Ltd. employs a full range of high-tech equipment for conducting aerial geophysical surveys. Aeroquest International Limited uses a helicopter to conduct aerial geophysical surveys with its proprietary electromagnetic systems.
