BASIN Database - Data Confidentiality

Data Confidentiality

A period of data confidentiality exists for most industry generated well and geophysical survey information. Information or documentation, which includes samples, data, records and reports submitted to the Boards (CNLOPB, CNSOPB) may be disclosed to any interested third party in accordance with relevant Acts after a period of confidentiality has expired. BASIN does not contain any privileged information. The period of data confidentiality is variable: for well data it depends on the classification of the well (exploratory, delineation or development) and the type of well data involved; for geophysical survey data it depends on the survey classification (exclusive or speculative). Periods of data confidentiality also vary between Provincial and Territorial jurisdictional areas.

Employees of NRCan (Natural Resources of Canada) - which includes the staff of the Geological Survey of Canada (GSC), Earth Science Sector (ESS) - who collect data and information for internal research purposes are usually given privileged access to, and use of, those data for a period of two years after their collection. At the end of the period of privileged access the data is usually made publicly available. In most cases these data are made available as soon as possible.

The following information is provided as a summary guide only, in all cases refer to the guidelines and Acts available through the appropriate regulatory agencies.

Well Data

The following table broadly outlines the confidentiality periods for various data and well classifications for offshore Nova Scotia and Newfoundland and Labrador wells. The period of confidentiality begin on the well termination date.

Geophysical Surveys

For offshore Nova Scotia and Newfoundland and Labrador geophysical surveys the period of confidentiality for speculative (non-exclusive) surveys is 10 years following the completion date of the survey, for exclusive surveys the data is held confidential for 5 years after the completion date. The completion date occurs 6 months after the field program has terminated.
