| wildcat |
A exploratory wellbore drilled in an unproved area to test for a new field, a new pay, a deeper reservoir, or a shallower reservoir. Also known as an exploration well. |

| new-field wildcat |
An exploratory wellbore drilled to search for an occurrence of hydrocarbon at a relatively considerable distance outside the limits of known pools of hydrocarbon, as those limits were understood at the time. |

| outpost wildcat |
An exploratory wellbore drilled to search for additional pools of hydrocarbon or to extend the limits of a known pool by searching in the same interval at some distance from a known pool. |

| stratigraphic test |
A research wellbore drilled for the purpose of gathering geologic information on the stratigraphy of an area. A C.O.S.T. well would be included in this category. |

| appraisal |
A wellbore drilled into a formation shown to be potentially productive of oil or gas by an earlier well for the purpose of obtaining more information about the reservoir. |

| delineation |
A wellbore drilled outward from a successful wildcat well to determine the extent of the oil find, the boundaries of the productive formation. |

| injection |
A wellbore that is drilled with the purpose of injecting fluids into a reservoir, usually for enhanced recovery. |

| general service |
A wellbore drilled to provide a service such as subsurface fluid monitoring, waste disposal, fluid storage, blowout relief and borehole re-acquisition. Not necessarily an E & P wellbore. |

| monitor |
A service wellbore drilled to allow continuous or periodic measurement of a property of the subsurface through time. |
