The Well Data Submission Requirements Manual outlines to industry the required format for well data submissions to the Commission. The file formats and naming conventions outlined in the Well Data Submission Requirements Manual are utlilized when submitting well data via the eSubmission portal. The data types that are not currently processed via the eSubmission portal will retain the file formats and file naming conventions when they are integrated into the portal.

A: If you have access to an electronic version of the file or scanned image, please send your query to Records and Information Services at You can also call the Well Data Help Line at (250) 419-4488.

The Commission email can handle file sizes up to 100MB, but you’re encouraged to advise us when sending files in excess of 25MB.  Within the eSubmission portal, users can upload files up to 250MB in size.  If your files sizes exceed these limits or you have additional concerns, contact the Well Data Help Line at (250) 419-4488 and inform them of the issue.  The most likely resolution will be to copy the files to a CD/DVD and courier them to Well Data Management at the following address. All files contained with the CD/DVD must follow the prescribed file naming conventions, as outlined in the Well Data Submission Requirements Manual. You may include the data for several wells on a single CD/DVD.  Mailing address: Well Data Management, BC Oil and Gas Commission, 2950 Jutland Rd, Victoria, B.C., V8T 5K2.

The date format portion of the file naming convention is always 7 characters.  The first 4 characters are always digits and represent the year.  For 2016, the YYYY is “2016”.  The second portion of the data format is for the month and is always three alphabetic characters.  For January, the MMM is JAN. The remaining months are FEB/MAR/APR/MAY/JUN/JUL/SEP/OCT/NOV/DEC.  The third and final portion of the data format is always two numeric characters.  For the first of the month, it is 01 and for the 22nd of the month it is 22.  Example: For September 3, 2016, it would be 2016SEP03.  The only exception to this is for injection and disposal, which are monthly statements whereby the file naming convention coincides with that month’s statement, where the file naming format is YYYYMM.  YYYY is a 4 digit year code and MM is the two digit month code, so for a May 2016 monthly injection and disposal statement, the date format is 201605.
