  • Frontier Exploration

    • Governments advance emerging plays in Eastern Mediterranean, North Atlantic

      Basins in the eastern Mediterranean Sea are of increasing interest following the discovery of deepwater gas offshore Israel. However, some of the newly-licensed areas could be more prospective for oil, according to presentations at IRN's Oil & Gas International Licensing Summit in London earlier this year.

  • Industry Interview

    • Joint venture combines parents' services to offer fresh approach to consulting

      In January, McDermott International and GE Oil and Gas formed io oil & gas consulting, a joint venture that looks to offer a holistic approach in developing front-end solutions for offshore fields. The London-based venture, which plans to expand into the US and Asia, says it will approach the full-field development as one system. Offshore recently met with io CEO Dan Jackson to discuss the company's goals, opportunities, and industry trends.

    • Barbados invites bids for offshore blocks

      Barbados' government will open large parts of the country's offshore area for bidding during 2015, with favorable terms for international oil companies. All these unlicensed blocks can be considered as a rank wildcat exploration area, and early movers will be able to pick up the best prospects. Mapping of the region's Cretaceous La Luna age-equivalent source rock - not previously feasible using the old seismic - is now possible, and the new data has led to identification of more than 20 large oil prospects.

    • 3D CSEM can play vital role in offshore exploration

      3D controlled source electromagnetic (CSEM) surveys map resistive bodies in the subsurface - fluid-driven parameters that correlate strongly with the fluid content and saturation of hydrocarbons where the larger the resistive body, the greater the response. Whereas most prospects generally have higher uncertainty in probability of success to start with based on seismic interpretation alone, adding EM data will enable better fluid predictions. When trying to optimize and prioritize a portfolio of prospects, 3D CSEM data provides operators with the ability to polarize their portfolio and identify areas with larger hydrocarbon accumulations where they are more likely to be economically viable.

  • Drilling and Completion

    • Feasibility study assesses two dry tree options for the Gulf of Mexico

      Operators in the Gulf of Mexico (GoM) are increasingly looking to ultra-deepwater (5,000-ft/1,524-m water depth) fields and more challenging reservoirs to deliver the hydrocarbons that the energy market demands and to satisfy their production growth objectives. DNV GL was granted an award by the Research Partnership to Secure Energy for America, partially funded by the US Department of Energy's National Energy Technology Laboratory, to manage a project to develop dry tree semi concepts for the ultra-deepwater fields in the GoM.

    • Advances in rotary steerable systems improve efficiency

      The first patents for so-called steerable systems were issued in the late 1800s, and applied primarily in water wells. A full century passed before modern rotary steerable systems (RSS) made their oilfield debut, reportedly on BP's Wytch Farm extended-reach play. Today, with depressed oil and gas prices, operators are primarily concerned with cost reduction. Offshore asked four RSS providers for an update on their latest efforts to improve drilling efficiency and add value.

    • Red Hawk stands as first spar ever decommissioned in GoM

      The Red Hawk spar made history throughout its design life, commissioned and decommissioned as the first of a kind. Heralded as the first cell spar ever built, it remains the lone cell spar ever fabricated just slightly 10 years after its inception. Decommissioned in September 2014, it then earned distinction of being the deepest floating production unit retired in the Gulf of Mexico.

    • Deepwater construction vessel provides improved stability, novel pipelay

      In February, the two main cranes and vertical lay system were fitted on Ceona's new deepwater field development vessel Ceona Amazon at the Huisman yard in Schiedam, the Netherlands. The 199.4-m (654-ft) long vessel, which will be the flagship of Ceona's growing fleet, is designed to perform in multiple pipelay and operational modes, including heavy lift and subsea construction.

    • Lewek Constellation heads to the Gulf of Mexico

      EMAS AMC has introduced the Lewek Constellation, a unique vessel that finds itself in an increasingly unique situation. By the time it hits the waters of the Gulf of Mexico in April, the subsea construction vessel will have a backlog of work worth more than $500 million with a $120-million West African job already completed. At nearly 180 m (591 ft) long, Lewek Constellation is a DP-3 ice-classed, multi-lay offshore construction vessel with ultra-deepwater pipelay and heavy-lift capabilities.

    • Industry advances deepwater production riser technology

      This issue of Offshore magazine includes an update to the Deepwater Production Riser Systems & Components Poster. Nearly five years have passed since the last edition of this poster was published, and there have been several advances related to riser technology over this short period of time.

  • Productions Operations

    • Real-time measurements, data management enhance operational efficiency

      A better solution to protect high-value investments in offshore and subsea installations is to take a proactive approach, using real-time downhole, subsea, and surface measurements to monitor and analyze well performance. This enables operators to curtail performance deterioration and deter imminent failure of downhole artificial lift equipment, as well as to tailor preemptive responses to potentially unsafe conditions such as hydrate, asphaltene, or wax precipitation.

    • Emerging markets to drive FPU construction over near term

      Through the end of the decade, the largest markets for floating production systems are expected to remain Brazil, West Africa, and Southeast Asia. However, there are new areas of growth, particularly in East Africa and the Mexican portion of the Gulf of Mexico. The fastest growing segment is forecast to be gas processing units, namely FLNGs and FSRUs, which are expected to account for 25% of all floating production systems capital expenditures over the next five years.

    • Sevan adapts circular floaters for future regasification, FLNG needs

      Sevan Marine is developing new applications for its cylindrical floater technology. To date, the Arendal, Norway-based contractor has designed and supplied floaters for use as FPSOs, drilling rigs and accommodation units. More recently, its focus has been on concepts for floating storage and offloading units; gas-handling operations such as FLNG and floating storage and regasification; and studies for power plants and carbon capture.

    • Digital oilfield offers new model for production optimization

      Remote monitoring solutions help oil and gas producers visualize their operations with real-time, comprehensive data that is easily transformed into actionable information to help achieve goals of reduced downtime and increased productivity. Through cloud computing, these solutions are not only applied quicker, but also are more easily scalable as other transformative technologies emerge in the future.

    • Dual compact flotation unit delivers big gains in oil removal efficiency

      Schlumberger's EPCON division in Porsgrunn, Norway, has redesigned its compact flotation unit (CFU) technology. The resultant EPCON Dual CFU, the company claims, offers major improvements in separation and treatment of produced water on fixed and floating installations. The original EPCON team began working on the CFU concept in the late 1990s, with the first offshore installation completed on a Norsk Hydro's Troll C platform in the Norwegian sector in 2001.

  • Subsea

    • Subsea processing moves forward with challenges in tow

      New technology has been implemented gradually both in greenfield developments and modifications of existing fields, but for many of the technologies that adaptation is still low. There are several key subsea technology developments in the works that could reduce future barriers for widespread use. Subsea processing is the concept of gradually moving the entire topsides processing facilities to the seabed which would create better financial returns due to increased recovery.

  • Pipelines & Flowlines

    • Offshore industry examines integrity of CO2 pipelines

      With energy security and climate change at the top of the global agenda, climate change mitigation technologies such as carbon capture, utilization and storage (CCUS) are gaining momentum. The number of offshore CO2 pipelines is therefore expected to grow significantly in the future. CCUS technology offers a solution for both supporting production of incremental hydrocarbon reserves from existing fields while at the same time storing CO2 away from the atmosphere, avoiding climate impacts.
