Abstract Options for abandoning offshore producing fields are broad and many variations exist in the world, each having advantages and disadvantages. Platform removal affects both governments and companies and thus, ultimately, affects the bottom line of a project. Typically, wells will be plugged and abandoned, topsides will either be taken to shore or recycled, and substructures can be totally or partially removed, or left in place. Abandoning offshore fields has four distinct stages: (1) develop, assess, and select options and create a detailed planning process that includes engineering and safety preparedness; (2) cease oil or gas production and safely plug and abandon wells; (3) removal all or part of the offshore structure (in most cases); and (4) dispose of or recycle removed equipment. Economic issues include costs, fiscal treatment, and relevant legislation. Operators have different options for offshore installation removal and disposal. The best option depends on several factors such as type of construction, size, distance from shore, weather conditions, and removal complexity. The paper discusses the decommissioning options, cost estimates, fiscal treatment, and regulatory framework.
