Abstract All oil and gas wells inevitably shifts from asset to liability, whether the result of reaching its economic limit or sustaining irreparable damage. At the end of its life cycle, a subsea well and its supporting infrastructure must be carefully dismantled to ensure they pose no safety or environmental threats and to salvage useable components. In addition to creating significant safety and environmental hazards, failure to properly abandon a subsea well can lead to a noncompliant status with regulatory agencies and undermine an operatorโs image. Despite its multiple liabilities, abandonment offers no real return on investment, underscoring the importance of minimizing cost. The challenge is to retrieve the wellhead without damage so it can be used again, minimizing or eliminating damage not only to the wellhead but also to personnel and environment. This paper will describe the technological tool system available to retrieve subsea wellheads in a single trip. This technology serves as an alternative to equipment that poses environmental and safety hazards, such as mobile offshore drilling units and explosive severance devices. By latching on to the external profile there is no damage to the internal seals. Also the external latch procedure allows more clearance to allow the cuttings to flow out of the ports and away from the working mechanism. The wellheads retrieved have a much greater chance of being re-used with minimal damage. The external latch design allow for more strength and less chance of tool failure. This paper will also discuss some global case histories.

Abstract This paper summarises original development work implemented by Ocean Resourceinto a new type of Unmanned Production Buoy facility, the Sea Producer. Thiswork, which is both comprehensive and wide-ranging, covers the use ofautonomous buoy technology to develop various offshore oil and gas productionscenarios which would otherwise be uneconomic or indeed impossible. Recentlythis technology has received considerable interest as it represents, for somesmaller developments, possibly the only sensible and economic way forward. Thedesign concept is flexible and has applications well beyond simple production. Ocean is carrying out on-going development work into the use of the concept forcarbon sequestration allied to enhanced oil recovery. This novel developmentwill provide an initiating technology for offshore carbon sequestration againat hitherto highly economic costs. The detail of this is, however, beyond thescope of this paper. Ocean Resource has developed and pioneered the concept of remote offshore oilor gas production from an unmanned production buoy over a period of 20 yearsand is the only company with specific experience and expertise in this complexarea. Ocean has designed, built, operated and maintained its own high stabilitybuoy systems and has completed a number of buoy designs for working buoysystems in use with Apache, Mossgas Pty, Exxon-Mobil and others for oil relatedoperations. More recently Ocean Resource has been responsible for the design ofa 5MW Power Buoy for CNR International UK Ltd (Canadian Natural Resources). Unfortunately Monitor Oil PLC, the principle constructor, went into liquidationprior to completion of the project but it is envisaged that this unit, which is95% complete will shortly be redeployed on another field. The Power Buoylocated at Dundee is subject to an option agreement for this purpose. Ocean Resource's low cost autonomous buoy systems represent a game-changingtechnology that will enable the economic development of hitherto unexploitableor stranded oil and gas reserves. The technology is generally branded as SeaCommander where it relates to field control buoys (a developed product) and SeaProducer where it relates to production. Sea Producer enables a step-change in offshore development expenditure loweringcapital costs at the start of project together with greatly reduced operationalcosts leading to low " through-life" costs for standalone, step-out developmentsor early production scenarios. Furthermore the relatively minimal nature of theoffshore facilities comprising the buoy and storage system leads to rapiddeployment and hence faster income and profit return to any offshoreproject. The unique autonomous buoy technology has been developed by Ocean Resource overa period of 20 years and is an evolution of existing systems first deploed inthe 1980's. It is therefore both mature and proven. It can be used for sub-seaoil and gas field control, remote pigging, multi-phase pumping, chemicalinjection, subsea production support and remote flaring.

Abstract An adventure is something that is exciting and associated with the taking ofrisks. Pazflor project has certainly been an adventure and a huge capital andtechnological investment for Total. The stakes were high with 65% of the production being a heavy viscous oil fromMiocene reservoirs using worlf first technologies, combined with thesimultaneous production of a lighter oil from a deeper Oligocene reservoir andover a very extensive development area. Pazflor is a truly global project with a worldwide control organization and avery demanding schedule. The First Oil achieved on 24th of August 2011, onemonth before the initial planned date, showcased Total's ability to managehighly technological huge international projects.

There is plenty to be optimistic about in the upstream oil and gas oil sector. In this article, the Energy Industries Council (EIC) focuses on offshore opportunities globally, and identifies the hot spots of activity. It will also examine some of the key issues facing the sector and the energy supply chain today, such as the need to maximize oil and gas recovery from challenging environments and new offshore fields, and the need to reduce costs and innovate.

It will also examine some of the key issues facing the sector and the energy supply chain today, such as the need to maximize oil and gas recovery from challenging environments and new offshore fields, and the need to reduce costs and innovate. The EIC's project tracking database, EICDataStream, which tracks more than 9,000 active and future projects across the global energy industry, currently shows 1,075 offshore projects that are active or proposed. Together, these represent a total potential investment value of USD 1.27 trillion.
