Most well records in Alberta are open to public inspection. However, wells that meet certain criteria may be kept in confidential (tight hole) status. To be considered for confidential status, a well must be classified as an exploratory well, or there must be extenuating circumstances (defined in regulation as conditions beyond the control of the operator, preventing the operator from utilizing the competitive advantage from the information obtained from a well).
The AER provides listings of confidential and confidential below (CB) wells in the province of Alberta. Updated daily, these listings include: well locations, licence numbers, licensee operator codes, company names, well confidential types, confidential depths for CB wells and the confidential release dates.
