  • Hydrate characterization and dissociation strategies

    James M. Pappas

    Inhibitors will fail to prevent hydrate formation in subsea jumpers if proper mixing does not occur.

  • Mobile enhanced oil recovery for America’s small oil producers

    Robert Zubrin, Thomas Henshaw, Jim Siebarth, Boris Nizamov, Colin Apke and Mark Berggren

    Pioneer Astronautics is developing truck-portable equipment for generating CO2 on site to make enhanced oil recovery feasible for the small oil producer.

  • Operators move to the next level of subsea development

    Richard Vernotzy

    Since the beginning of the upstream industry’s migration from dry land into shallow- water arenas, and subsequently into deeper water depths of 600-plus ft, the development of reserves in ever-greater water depths to 10,000 ft has brought on significantly greater volumes of reserves, along with greater producing rates. This has required the development of a vast amount of new technology to bring these reserves to the marketplace.

  • Optimizing hydraulic fracturing enhances gas production in Saudi Arabia

    Zillur Rahim, Hamoud Al-Anazi, and Adnan Al-Kanaan

    While hydraulic fracturing is an essential technology to improve gas production from tight gas reservoirs, often the expected post-fracture rate is not achieved, even though the fracture treatment is pumped, as designed. Saudi Aramco has applied best practices associated with gel and polymer systems and the breaking agents. Examples from Saudi Arabia confirm the successes achieved by identifying problems and following up with remedial actions.

  • OTC 2013 to focus on offshore regulation, expanding role of NOCs

    Nell Lukosavich

    With activity in the Gulf of Mexico back to pre-Macondo levels, and a plethora of new deepwater discoveries off Brazil, West Africa, Southeast Asia and the Eastern Mediterranean, a special emphasis is being placed during OTC 2013 on industry self-regulation, government policy and the increasing role of NOCs around the world.

  • Regional Report: Gulf of Mexico

  • Shale gas emerges from low price fog as liquids excel

    Kurt Abraham

    Foggy mountain mornings are commonplace in the Appalachian Mountains of Pennsylvania, West Virginia, western New York and southeastern Ohio, home to the Marcellus shale. Early in the morning, at or before sunrise, visibility can be less than one-tenth of a mile.

  • The risk of kidnapping: What oil companies need to do

    Tess Baker and Sam Collard

    Despite recent media focus on the In Aménas gas plant attack, there are also many other security threats that face overseas workers, especially in the form of kidnapping for financial gain.

  • Topsides engineering best practices for lightweight design

    Kent McAllister and Hickman Brown

    An overriding factor in any deepwater project is cost. Because the weight of both the structure and the topsides production facility directly impacts cost, it must be a top priority. By reducing the weight of a 20,000-ton topsides by 15%, it is possible to slash capital costs of the project by $100-150 million.

  • Advanced method cuts time and costs for EOR modeling

    Dr. Lindsay Wood

    A sustained high oil price is leading major oil and gas companies to reassess their mature assets, which traditionally would have been sold to smaller operators, when the decline in production reduced the operating margins for the asset.

  • Are UK CCS projects finally poised for take-off?

    Jeff Chapman

    Depleted oil and gas fields and saline formations in the UK sector of the North Sea have the potential to hold vast quantities of carbon dioxide (CO2) as part of carbon capture and storage (CCS) projects. So far, no sizeable pilot schemes have been established in the UK, but in March, two projects were selected as candidates to receive funding as part of a £1-billion ($1.5-billion) UK government-backed competition aimed at stimulating the sector.

  • Bridon creating high-tech hub for next-generation rope development

    Bridon’s rope production dates back to the 18th century, when it made ropes from natural fibers, such as jute. Now the company manufactures steel wire and synthetic ropes, including high-strength ropes for offshore heavy lifting and deepwater mooring.

  • Carrying the next generation of offshore mega-structures

    Michel Seij

    In February, the world’s largest semisubmersible heavy transport vessel set out on its maiden voyage, carrying the world’s largest semisubmersible offshore platform hull. The Dockwise Vanguard performed its first float-on operation in South Korea, where it was built, before carrying the Jack/St Malo hull, which weighs almost 56,000 tons, to Kiewit yard in Ingleside, Texas. It is expected to reach its destination in early May. With a bow-less design that enables loading of longer cargoes and a loading capacity of up to 110,000 tons, the Dockwise Vanguard is intended to cater to the next generation of large offshore structures. Michel Seij of Dutch-based Dockwise spoke to World Oil about the rationale behind building this $240-million vessel.

  • Decision time approaches for pioneering subsea compression technology

    Pascal Montoulives and Matthias Owe

    Gas from Ormen Lange field offshore Norway will probably need compression by the end of this decade, to push it up to the Nyhamna processing facility onshore. Faced with this challenge, Shell, Statoil and their partners have been carrying out pioneering tests on subsea compression technology, which can be powered by subsea cables from the shore, removing the need for any offshore topside equipment, Fig. 1. As the decision time approached on whether to proceed with a project that Shell hopes will revolutionize subsea production, World Oil spoke about the latest developments with Pascal Montoulives and Mathias Owe, two of the engineers most heavily involved with the technology.   industry, whether this funding could finally kick-start the sector.

  • Are UK CCS projects finally poised for take-off?

    Jeroen Van Keep

    The P-63 Floating Production Storage and Offloading (FPSO) vessel, developed specifically to work in Brazil’s offshore Papa Terra oil field, is unique in that it will be the first FPSO vessel to utilize gas-fueled engines to produce more than 100 MW of power. The contract to supply the three main power modules to achieve this demanding output was awarded to Wärtsilä. This also includes commissioning, start-up and operational supervision.

  • New challenges confront the UK North Sea
