A well that is drilled to evaluate the resources that may be present. In some cases it is used to evaluate the feasibility of sequestering carbon dioxide in the subsurface.

A well drilled to find a new field or to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir. Farm-in

 

A well drilled to find a new field or a new reservoir in a field previously found the be productive of oil or gas in another reservoir.

A well drilled to find oil or gas in an unproved area, to find a new reservoir in an existing field previously found to be productive of oil and gas in another reservoir or to extend a known reservoir.

a well drilled in an unproved area, either to find a new oil or gas reservoir or to extend a known reservoir. Sometimes referred to as a wildcat.

A well in an area where petroleum has not been previously found or one targeted for formations above or below known reservoirs.

A well drilled to an unexplored depth or in unproven territory, either in search of a new reservoir or to extend the known limits of a field that is already partly developed.

A well drilled in an unproved area, either to find a new oil or gas reservoir or to extend a known reservoir. Sometimes referred to as a wildcat.

A well drilled into a previously untested geologic prospect to determine the presence of gas or oil.
