Many offshore decommissioning costs are higher than necessary because of decisions made during the initial engineering and construction for an oil or gas field.

With a high demand for plug and abandonment (P&A) of subsea wells in the future on the Norwegian continental shelf, industry is challenged to find alternatives and rigless technologies that can make P&A operation more cost-effective and -efficient.

This paper describes the preplanning and execution of Australia’s largest subsea well-abandonment campaign to date.

As an operator approaches the end of a field’s life, the remaining value may lie predominantly in a low-cost decommissioning delivery coupled with some upside value from the retention of critical infrastructure to enable maximum regional resource recovery.

In September, a technical workshop was held on the topic of injection-induced seismicity in Banff, Canada. It brought together industry and technical experts to discuss the increasingly important topic of induced seismicity associated with various injections during oil and gas activities.

In the northeastern desert of Utah, a new type of oil sands extraction technology has been born. The ­company behind it claims the process is the most cost-effective and environmentally sound way to develop oil sands.

As decommissioning costs mount in the US Gulf of Mexico, the Bureau of Ocean Energy Management (BOEM) is looking to change financial requirements for ­lessees and operators in federal waters for the first time in more than 20 years.

This is an update on several managed-pressure drilling (MPD) technologies and downhole drilling performance-enhancing tools in use onshore and is the first of a two-part series. The second article on offshore MPD technologies will appear in the February issue of JPT.

Downhole data acquisition by fiber-optic technology, particularly distributed fiber-optic (DFO) sensing, has gained rapid acceptance. Compared with conventional data acquisition, DFO provides a much better understanding of well and reservoir behavior.

This month, Mexico will begin opening data rooms as it prepares for its first upstream bidding round involving foreign participation.
