Fossils into Fuels - Oil & Gas exploration -  Oil and Gas
Exploration  A variety of technologies are employed in the oil
and gas industry to identify oil and gas reserves, to access
those reserves, and to extract and deliver the products. The
following subsections provide an overview of current
technologies employed in oil and gas exploration and drilling.
The exploration for oil and gas, which may be quite time- and
effort-intensive and rely on the collection and detailed
analyses of extensive geologic information, involves a number of
activities, including the following:  While past surveying and
mapping activities employed invasive techniques that included
explosive seismic profiling and extensive drilling to map and
locate potential reservoirs, modern exploration involves the use
of non-explosive reflection seismic profiling, together with
seismic imaging software and computers, to interpret geological
and geophysical data more completely. Reflection seismic
profiling transmits acoustic vibrations (seism
