An AIRBORNE GRAVITY Survey involves the use of a stabilised gravity meter installed on a fixedwing aircraft, to acquire data over a given area concerning the earth's gravity fields.

Mounted in a light aircraft, and steered by satellite GPS navigation, SEEPFINDER records the presence of thin molecular oil films on the surface of the sea.

GRAVEX is an airborne gravity sensing system providing high resolution exploration data.

The objective of surveying with a multi-channel, gammaray spectrometer system and a large volume gammaray sensor is to detect subtle characteristic radiation patterns as indicators of subsurface hydrocarbon accumulations over petroliferous terrain.

Radiometrics, or Gammaray Spectrometry, although used in oil & gas exploration, is more widely used in mining exploration. Installed on either fixed-wing aircraft or helicopters, and combined with other sensors, such as EM, GRAVEX and magnetics, a radio-metric system is a very cost effective geological and geophysical mapping tool.

The measurement of gradients of the earth's magnetic field from an airborne platform has been advocated for many years. In 1954, Wickerham proposed the use of what is essentially a gradient along the flight direction (longitudinal gradient).

High-resolution Aeromagnetic maps from data acquired by a total-field magnetometer reflect the underlying geology of the survey area. Such maps are invaluable tools for explorationists working in all kinds of environments, whether forest, mountain or desert.

ISMAP is an excellent tool for mapping geological structure in a wide range of tectonic settings, including new and mature basins in both onshore and offshore environments. It involves the use of high-sensitivity, high-resolution airborne magnetics to resolve very low-amplitude (micro-magnetic) anomalies (1nT to 5nT) originating from structures within the essentially non-magnetic sedimentary column, as well as high amplitude features from the crystalline basement.
