Creekology is a petroleum prospecting method which appeared in the 19th century in US south gas-oil states.
[1] Creekologists also placed wells on singular points of a territory in accordance with landscape features.
The placing of wells often occurred near, or on, linear objects - erosion relief forms (valleys, creeks,[2] etc.)
In the middle of the 20th century some geologists formed an idea about existing fault-fold systems in the Earth's crust, in sediment cover, and this gave creekology a "scientific base".
Now some geologists mark probable gas-oil areas with the help of space image lineation interpreting.
