StatoilHydro lets contract for Troll B gas injection

LONDON, Aug. 19 -- StatoilHydro has let a $100 million contract to Subsea 7 to design and install Troll B gas injection facilities to improve oil recovery at the country's largest gas field in the Norwegian North Sea. Precommissioning will take place in 2010.

Troll field lies on the Norwegian Continental Shelf about 70 km northwest of Bergen in 300-340 m of water. The development is part of StatoilHydro's 10 billion-kroner plan to manage the resources and boost recovery of reserves at Troll by 17 million bbl. The company submitted its plan to the energy ministry in June.

A single gas injection pipeline and a control umbilical will connect two separate subsea satellite wells to the Troll B platform—a floating process and accommodation platform with a concrete hull. One well will be 3.5 km and another 6.5 km south of the platform.

Subsea 7 will engineer, procure, fabricate, and install a 6.5-km, 12-in. rigid pipeline, incorporating inline and end structures for connection to the satellite wells, in addition to the control umbilicals. It will use one of its new vessels to install two 200-tonne satellite structures.

The company's office in Stavanger will begin implementing the contract immediately. Pipeline fabrication will be carried out in early 2009 at Subsea 7's new North Sea Spoolbase at Vigra on Norway's northwest coast. Pipelaying operations are scheduled for 2009 with one of its specialized reeled pipelay vessels.

The contract is a call-off of an option under an existing Subsea 7 Troll contract with StatoilHydro, Subsea 7 said.

Global LNG: Adjusting to New Realities

Fri, Mar 20, 2015

Oil & Gas Journal’s March 20, 2015, webcast will look at how global LNG trade will be affected over the next 12-24 months by falling crude oil prices and changing patterns and pressures of demand. Will US LNG production play a role in balancing markets? Or will it add to a growing global oversupply of LNG for markets remote from easier natural gas supply? Will new buyers with marginal credit, smaller requirements, or great need for flexibility begin to look attractive to suppliers? How will high-cost, mega-projects in Australia respond to new construction cost trends?

US Midstream at a Crossroads

Fri, Mar 6, 2015

Oil & Gas Journal’s Mar. 6, 2015, webcast will focus on US midstream companies at an inflection point in their development in response to more than 6 years shale oil and gas production growth. Major infrastructure—gas plants, gathering systems, and takeaway pipelines—have been built. Major fractionation hubs have expanded. Given the radically changed pricing environment since mid-2014, where do processors go from here? What is the fate of large projects caught in mid-development? How to producers and processors cooperate to ensure a sustainable and profitable future? This event will serve to set the discussion table for the annual GPA Convention in San Antonio, Apr. 13-16, 2015.

This event is sponsored by Leidos Engineering.

The Future of US Refining

Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
