    • Shell expands presence in deepwater GoM with Mars B

      Shell's Mars B project, located in the deepwater Gulf of Mexico, produced first oil in the first quarter of this year. It is the first time that significant infrastructure has been added to an existing deepwater field in the Gulf, says Shell.

    • Liwan marks first-ever deepwater gas development offshore China

      Husky's Liwan Gas Project is the first deepwater gas development offshore China. The project, in block 29/26, delivered first production this year, approximately seven years following its discovery and is one of the fastest developments in the world for a large-scale gas discovery in deepwater.

    • Statoil commences production at Gudrun

      Statoil ASA and its partners commenced production of the $3.4 billion development of the Gudrun oil and gas field in the North Sea on June 16, 2014, making it the first new Statoil-operated platform to come onstream on the Norwegian continental shelf since 2005.

    • Total adopts all-electric, subsea multi-phase approach for mixed-crude CLOV development

      In June, Total lifted first oil from CLOV, its fourth deepwater development "pole" in block 17 offshore Angola. Like its predecessors Girassol, Dalia and Pazflor, CLOV routes production through a network of subsea flowlines to a spread-moored FPSO.

    • Papa-Terra marks first use of dry tree floating technology offshore Brazil

      Petrobras started production from the Papa-Terra field on Nov. 11, 2013. Papa-Terra is a heavy-oil field in block BC-20 of the Campos basin offshore Brazil in 1,190 m (3,903 ft) of water. Development consists of an FPSO, the first tension leg wellhead platform in Brazil, and a tender assisted drilling unit.

    • From the archives: Pre-salt plays buoy Brazil's offshore development plans

      Selected from the July 2011 issue of Offshore, this article describes how the country's pre-salt discoveries "transformed the nature and focus of its oil sector."

    • Offshore celebrates 17 years of posters

      Seventeen years ago, the late Editor-in-Chief Leonard LeBlanc and Sales Manager David Davis of Offshore magazine welcomed a proposal from Mustang Engineering (now Wood Group Mustang) to publish a worldwide survey of offshore pipelay vessels. Offshore agreed to publish the survey as a visually graphic poster to represent the information. This poster started the series in June 1997, and now, 115 posters have been published, and more than four million printed copies have been distributed as supplements inside the magazine, and at numerous global industry conferences.

    • Chemical remedial sand control using the subsea flowline succeeds

      Sand production is a major concern to the industry and is more critical today, especially in offshore environments where tolerance to sand production is low. Sand influx into the wellbore may lead to problems such as valve and pipeline erosion, sand deposits in separators, and economic loss from production limitations. Mechanical sand control methods are considered reliable and there are options available, from simple to sophisticated, depending on the situation.

    • Local content rules in Nigeria expected to transform West Africa

      In 2010, the Nigerian Oil and Gas Industry Content Act, or the Local Content Act as it is commonly called, became law. The act had been 10 years in the making and prescribes minimum thresholds for the use of local services and materials with the overarching objectives of ensuring on-going job creation and improving skills of the local labor force as well as participation and ownership for local Nigerians in the country's developing oil and gas industry.

    • Island nations off East Africa hold frontier exploration potential

      In light of the recent discoveries that have been made offshore East Africa, the archipelagos of the Indian Ocean have received more attention from the international oil and gas industry. While the industry's interest is still somewhat nascent, there is a long road ahead before the hydrocarbon potential thereof can be wholly assessed.

  • Middle East

    • Subsea power, control advances extend West Delta Deep Marine network

      In 1999 INTECSEA, began a front-end engineering and design study for the West Delta Deep Marine concession offshore Egypt in the Mediterranean Sea. The development was operated by the Burullus Gas Co., a joint venture among BG, state-owned EGPC, and Edison Gas, with the latter since replaced by Petronas Carigali. INTECSEA has continued to work with Burullus on subsequent phases of the development, which has been expanded farther from shore at 105 km (65 mi), and in deeper water to 1,024 m (3,359 ft).

  • Geology & Geophysics

    • SEG 2014 takes stock of geophysical technology, trends

      Two words that encapsulate the Society of Exploration Geophysicists annual International Exposition and 84th Annual Meeting in Denver are "innovation" and "integration." Of all the technologies involved in upstream oil and gas, none is more subject to innovations than is the geophysics side. Much of the innovation touted at the event involved integration of systems and programs into packages designed to give a bigger and better understanding of the subsurface to a range of disciplines for an improved life-of-field span. There was also increasing interest in the environmental aspects of offshore exploration.

  • Drilling and Completion

    • Research effort aims to enhance cement integrity in deepwater

      Improving cement integrity in deepwater applications is one of the primary foci of the National Energy Technology Laboratory (NETL), a division of the US Department of Energy. Within NETL's national laboratory system, under the direction of the Office of Research and Development, and in concert with industry and academia, work is advancing in many areas, from reverse circulation cementing to smart cement.

    • DeepStar study assesses cost-effective dry tree solutions

      DeepStar evaluated a large number of novel concepts for a common design basis, focusing on identification and characterization of key technical performance parameters, constructability, and economic factors. The economic factors are most important for these designs to be considered attractive for development of marginal fields with short field life and fewer wells. The authors present the alternative development themes for obtaining dry tree and direct vertical access capability.

  • Subsea

    • Fluid sampling, subsea processing help maximize deepwater development

      Growth trends in deep and ultra-deepwater development demonstrate a need to increase hydrocarbon output while improving the asset's net present value. The new application of subsea fluid sampling systems, subsea separators, compressors, multi-phase pumps, and the qualification of critical components would enable remote long-distance assets (even with low reservoir pressure) to be developed economically. Furthermore, the synergy of subsea fluid sampling and subsea processing has evolved into a solution for transforming potential oil and gas reserves into economic return on investment.

  • Flowlines and Pipelines

    • In-line inspections guide offshore field management decisions

      Assessing the working condition of aging offshore pipelines is a challenging process made more complicated by their location on the seafloor and limited access points. An operator off the coast of West Africa faced such challenges in its plans to inspect 160 shallow-water offshore pipelines that had been in service for decades.
