Decommissioning
The North Sea Transition Authority has published its first table identifying 13 operators that are behind schedule in decommissioning their inactive North Sea wells.
Estimates commissioned by the Australian government suggest that increasing efficiency will lower costs for decommissioning offshore Australia.
Marine contractor also approves the construction of a new heavy-transport ship.

This paper demonstrates a new way to create gas-tight seals during well abandonment, overcoming the limitations of traditional methods and reducing the operator’s liability and potential environmental impact after decommissioning has been completed. -
Decommissioning and abandonment comes with its share of unexpected surprises, but many of those surprises could be avoided merely through better planning and care.
-
The next big wave of decommissioning and abandonment projects is set to occur in the Asia-Pacific region, and APAC’s operators are now tasked with finding cost- and time-effective ways of unwinding their huge agglomeration of wells and facilities.
-
This paper discusses studies conducted on two California offshore fields that may be abandoned in the near future. These studies examined the feasibility of repurposing these fields for offshore gas storage by using their reservoir voidage and existing pipeline facilities.

The outlook in the UK is a case study of the squeeze facing E&P in other basins where operators are trying to pay to sustain production with discoveries, while plugging and abandoning old wells, all paid for by the lean cash flow due to low oil prices.
-
Scientists at the National Oceanographic Centre have released a review of how marine robotic capabilities can support the environmental monitoring needed for decommissioning oil and gas installations.
-
When energy companies go bankrupt, the cleanup of their old oil and gas wells must take priority over paying off creditors, the Supreme Court of Canada ruled on 31 January.
-
An influx of new investment and operational efficiencies borne out of the oil price downturn have led to a drop in projected decommissioning costs. Decommissioning multiple wells in one campaign helped some operators achieve time savings of 33% per well.
-
A new survey of international experts has seen a swing of opinion away from mandatory removal of obsolete offshore infrastructure, reflecting an acknowledgment that offshore structures often develop into artificial reefs and form a part of the ecosystem around them.
-
A recent spike in production has engendered a cautiously optimistic outlook for the UKCS, but will it do anything to stave off the overall decline of the mature basin?
