Decommissioning of offshore oil and gas production facilities in California has always been and will continue to be a controversial and hotly debated topic. This Decommissioning has been occurring since the early part of the 20th Century and most recently involved four offshore platforms, a pier, and an island in State waters. It also involved the abandonment of over 23 sub sea wells and associated debris off the Santa Barbara, California Coast. Much was learned from these many decommissioning projects, and organizations were formed to coordinate future decommissioning projects and discuss alternatives. This presentation will summarize the lessons learned from past decommissioning projects, future projects and options available for future projects. There will be a discussion on the positions of the public, environmental communities and government on the approval process, facility removal process and final disposition of the facility. Focus of the presentation will be on the process that could be used to develop viable decommissioning options.
