http://www.americanoilinvestments.com/articles/Oil-Exploration_Summary.html Oil exploration refers to the search of hydrocarbon deposits by geologists. To study landforms and do seismic analysis are just two examples of the techniques used to find those deposits. Advanced technology is often needed to find and determine the capacity of deposits, also known as reservoirs.
