Description


The Blackback P&A Environment Plan covers the permanent plugging and abandonment (P&A) of the Blackback A-1A, Blackback A-2 and Blackback A-3 wells. The Blackback subsea facility is located approximately 90 km from shore at approximately 400m water depth in Production Area VIC/L20. The Blackback P&A campaign will utilise the Ocean Monarch MODU, which is already in Bass Strait, to P&A the three Blackback subsea wells. The three wells will be permanently abandoned by installation of cement plugs as barriers, followed by the retrieval of wellheads from the seafloor. This campaign will eliminate loss of containment risks associated with live hydrocarbon wells and will remove obstructions and snag points for commercial fishermen. The campaign is an ALARP action in its own right and should be considered in this context. P&A activities in the Blackback operational area are scheduled over an estimated 71 day period commencing in Q4 2018.
