Due to the large number of oil and gas wells in the United States, this national dataset has been broken up into three different comma separated values (.csv) text files. All data were obtained between March 1, 2021 and September 30, 2021.

As oil and gas wells are regulated by the states, available data as well as data quality vary tremendously. For those reasons, as well as ease of use and file size, this dataset limits the available attributes to the following:

 State - two letter postal code

 API Number - Available in most states, but in a variety of formats

 Name – Well name and number. In some cases, this was combined from two fields, in others, it was already

combined. In other cases, this field is not available.

 Operator – Name of company that operates the well

 SpudDt – The spud date is generally considered to be the date that the rig which will drill down to the target

geological stratum first touches the ground. This concept is often simplified to say the date that drilling

operations begin.

 Status – Current status of the well as of the time the data was downloaded. Some states combine this with well

type, while others do not provide this information.

 Type – Type of well (production, enhanced oil recovery, disposal, etc.) Some states combine this with the well

status, while others do not make it available.

 Lat – Latitude of well in decimal degrees. Almost all states make this available, but a few have been converted

from other formats, such as Universal Transverse Mercator (UTM).

 Long – Longitude of well in decimal degrees. Almost all states make this available, but a few have been

converted from other formats, such as Universal Transverse Mercator (UTM).

Efforts were made to include only currently active wells, along with those that had been recently proposed but are not active yet. As the data and the legal code that they are based off of varies significantly from state to state, there is a certain level of interpretation in this process which could deviate from realities in the field in some cases. Additionally, there were thousands of wells, especially in OK and WV, that were given coordinates that render outside of the state boundaries, and these were excluded from this compilation. It is entirely likely that there are additional wells with bad latitude and longitude coordinates where this state-level verification was not sufficient to identify erroneous results published by the various states. Therefore, it is recommended to verify the location or any other attribute of any specific well with the regulatory agency of the state in question.

This data was compiled by FracTracker Alliance based on data reported by the various state-level regulatory bodies. In some cases, these agencies have more than one data source. Because of this, there are sometimes two links for a single state. Some of these additional links may represent specific well selections, such as orphaned or abandoned well lists, which may or may not be what the user is looking for. Users interested in the most recent data for any state are encouraged to follow these links and search these agencies’ websites for the most recent version.
