A well drilled to find and produce oil or gas in an unproven area, to find a new reservoir in a field previously found to be productive or to extend the limit of a known reservoir.
A well drilled to find and produce oil or gas in an unproved area, to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir, or to extend a known reservoir.
A well drilled either in search of a new and as yet undiscovered accumulation of oil or gas, or in an attempt to significantly extend the limits of a known reservoir.
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 unproved or semi-proved territory for the purpose of ascertaining the presence of a commercial petroleum deposit.
A well drilled to test the presence of oil or gas in an undeveloped area.
a well that is not a development well, a service well, or a stratigraphic test well, as those terms are defined separately
A well drilled to find and produce oil or natural gas in an unproved area. Sometimes called a "wildcat."
Any well drilled for the purpose of securing geological or geophysical information to be used in the exploration or development of oil, gas, geothermal, or other mineral resources, except coal and uranium, and includes what is commonly referred to in the industry as "slim hole tests," "core hole tests," or "seismic holes".
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 find and produce natural gas or oil reserves not classified as proved, to find a new reservoir in a field previously found to be productive of natural gas or oil 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 hole drilled to find and produce oil in an area previously considered unproductive, to find a new reservoir in a known field or to extend the limit of a known oil reservoir.
