Recent improvements in the resolution of aeromagnetic surveys have sparked a renewed application of multi sensors magnetic surveys for hydrocarbon exploration. High resolution aeromagnetic surveys can be used for mapping of faults and fracture systems throughout the sedimentary section, in addition to the traditional task of defining basement structure and lithology.

Mining Exploration

Acquisition of airborne magnetic data is an integral part of most mining airborne geophysical surveys, serving as a valuable addition to electromagnetic and radiometric surveys. Airborne magnetics is used for target hunting and detailed geologic mapping of structure and lithology. Line spacing and flight altitude are the survey parameters controlling the survey resolution.

Gradiometric System Configuration

Advantages of acquiring gradiometry data include the ability to calculate the horizontal gradient vectors from both the longitudinal and transverse gradients, improving the interpolation between lines, particularly for structural features parallel to sub parallel to the flight lines.

Magnetic Sensor Towed by the Helicopter

GDS offers single sensor magnetic towed-bird systems for total field magnetic measurements. This configuration is designed to ensure rapid deployment capabilities and flexible use of a variety of light helicopters lowering mobilization costs.

Stinger-mounted Installation

Stinger-mounted magnetometers tend to be more stable in rugged conditions and allow ground-clearance to be minimized, to optimize spatial detail in the data. The versatility of bird-mounted magnetometers tends to reduce installation time and mobilization cost, for the most economical surveys.

VLF-EM can be added conveniently to stinger-mounted or bird-mounted surveys, to map electrically conductive features.

Having flown many hundred thousands of line kilometers of aeromagnetic surveys in a multitude of geologic environments, the staff of GDS has profound experience in processing and interpretation of geophysical data. Our geophysicists combine state-of-the-art hardware and software tools with experience and knowledge to process and interpret data, with attention to detail and thoroughness.
