Although Albertans can see most well records in the province, some wells are kept confidential and given a “tight hole” status. We regularly update our list of confidential and confidential below (CB) wells in Alberta. This list only includes basic well data; it does not include details such as drilling and completion data. Section 12.150 of the Oil and Gas Conservation Rules explains what data are considered confidential.
Well confidentiality is based on
- the well type,
- the substance the well will produce, and
- the well’s Lahee classification.
For more information, see table 7.8 in Directive 056: Energy Development Applications and Schedules.
Updated daily, this list includes
- well locations,
- licence numbers,
- licensee operator codes,
- company names,
- well confidential types,
- confidential depths for CB wells, and
- confidential release dates.
