FAQ: What is "TRM"? A guide to oil and gas well completion types.

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

A successful producer
Used in the incremental recovery of additional oil or gas
Used to monitor reservoir integrity or water quality
Used to supply fluids used while drilling

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**
Main Database	Downloaded data	Translation
* Value refers to a general class of wells and occurs only in summary data downloaded from the Web
AB	D&A	Well known to be abandoned, no plugging affidavit (PA) or plugging report (PR)
AI	SRV	Air injection
CBM	GAS	Coalbed methane gas producer
COI	SRV	Carbon dioxide injection
CP	MSC	Cathodic protection, a well associated with natural gas pipelines and transmission used to ground a pipeline other facility and prevent the build-up of a static electric charge
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)
GS	MSC	Gas storage
IA	D&A	Improperly abandoned
LOC	LOC	Location (new permit issued or insufficient data)
*	MSC	Miscellaneous, usually non-producing wells
N2I	SRV	Nitrogen injection
O&G	O&G	Combined oil and gas producer
OB	MSC	Observation well (usually associated with gas storage or water injection operations)
OIL	OIL	Oil producer
SI	SRV	Steam injection
SRI	SRV	Secondary recovery input/injection (an EPA Class II injection well)
*	SRV	Service wells, EPA Class II injection wells of various types drilled in support of oil and gas production
SWD	MSC	Salt water disposal
TA	D&A	Temporarily abandoned
TAI	SRV	Thermal and air injection
TP	LOC	Termination pending
TRI	SRV	Tertiary recovery input
TRM	LOC	Terminated permit, abandoned location (permit was allowed to expire or was cancelled)
UN	LOC	Unknown (as classified by KY Division of Oil and Gas)
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
