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, 300 – 398 Harbour Rd, Victoria, B.C., V9A 0B7.
