Survey
- Borehole
- a deep, narrow hole made
in the ground, especially to
locate water or oil.
- A narrow tube that digs
deep to collect a rock
sample of the ground

- Geochemical
Analysis
- Geochemical analysis can predict where
petroleum, metals, water, and
commercially valuable minerals can be
located—a branch of the science known
as geochemical prospecting.

- Magnetic
Survey
- Magnetic surveys record spatial
variation in the Earth's magnetic field.
In archaeology, magnetic surveys are
used to detect and map archaeological
artefacts and features.
- An aeromagnetic survey is a
common type of geophysical survey
carried out using a magnetometer
aboard or towed behind an aircraft.
- The principle is similar to a magnetic survey
carried out with a hand-held magnetometer,
but allows much larger areas of the Earth's
surface to be covered quickly for regional
reconnaissance.
- The aircraft typically flies in a grid-like pattern with height
and line spacing determining the resolution of the data
(and cost of the survey per unit area).
