To locate natural gas and remove it from the earth, geologic mapping,
surveys, and aerial photographs are used. However, recent technology is helping
find natural gas more accurately. Some of these methods include:
-
Magnetic Measurement — a measure of the magnetic field of base rock
to determine how much sediment is lying above it.
-
Satellite Imagery — helps identify surface structures and patterns
that aid in the search for probable underlying hydrocarbon deposits.
-
Gravity Mapping — determines the thickness of the basin or
sedimentary rock layer and helps identify base rock topography.
- Seismic Sound Wave Reflection — measures the time to various rock units that reflect acoustic energy.
