Creekology
Creekology is a petroleum prospecting method which appeared in the 19th century in US south gas-oil states. In its simplest form, it was the search for above-ground indications of oil, such as natural seeps.〔http://digital.library.okstate.edu/encyclopedia/entries/P/PE023.html〕 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,〔http://www.energybulletin.net/node/8298〕 etc.) - giving rise to the term ''creekology''. The success rates of some creekologists in the 19th century were very high - 80-90% of their wells gave production and more recent petroleum firms can only dream about such results.
==New creekology==
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". Linear forms in earth landscape connect with fault tectonics, and some folds near faults can be reservoirs of hydrocarbons. The non-fold types of traps mark by lineation too (paleo-rivers formed on faults). Now some geologists mark probable gas-oil areas with the help of space image lineation interpreting. This activity can be defined as "new creekology".
