There are many things that can happen to a well drilled in the search for oil and gas. The well may be:

There are three main ways to access Kentucky's oil and gas well data: the database search page, the map interface, or by purchasing data. Depending on how you access the Kentucky oil and gas well data, you might see a variety of well completion types in the result (or completion_result) fields.

Abbreviations used in the oil and gas well results column to describe well completion types

D&A D&A Dry and abandoned
DG GAS Domestic gas supply (i.e., non-commercial gas)
FF SRV Fire flood
FP LOC Forfeiture pending
GAS GAS Natural gas producer
GI SRV Gas injection (usually oilfield repressurization)

WD MSC Water disposal (can be produced water disposal or storm or waste water disposal)
WI SRV Water injection (an EPA Class II injection well)
WS MSC Water supply (usually drilled to supply water for drilling mud, but may also refer to a well drilled as an oil and gas test, but that was plugged back and left for the landowner to use as a domestic water supply well)
WW MSC Water well, for the most part similar to a water supply well, in this case, often associated with secondary recovery operations
