NPD ups eastern Barents, Jan Mayen resource estimates

A resource assessment of the southeastern Barents Sea offshore Norway and the area surrounding Jan Mayen Island northeast of Iceland indicates a 15% increase in estimated undiscovered resources on the Norwegian Continental Shelf to 390 million standard cu m of oil equivalent, the Norwegian Petroleum Directorate said.

The mapping exercise that led to the increased estimate was a step in the authorities’ process to open these areas for oil and gas exploration. However, NPD noted that Iceland has the right of use for parts of the shelf surrounding Jan Mayen and has already awarded licenses.

In the southeastern Barents, NPD mapped a 44,000 sq km area along the Russian sea boundary and estimated the potential resource at 300 million standard cu m with an uncertainty range of 55-565 standard cu m. The area is gas prone and only about 15% of the resource should be oil, NPD said.

The Bjarmeland platform farthest north and the Fedinsky high to the east are considered to be pure gas provinces, while the Nordkapp basin, Tiddlybank basin, and Finnmark platform are considered to be combined oil and gas provinces. Gas on the Fedinsky high could span the Norway-Russian border, NPD noted.

NPD found reason to believe that source rocks are present that have formed sufficient volumes of gas but that source rocks that form oil are not present to the same extent.

Geological knowledge of the southeastern Barents is relatively limited because no exploratory wells have been drilled and shallow scientific drilling has not yet been carried out. However, a number of wells have been drilled in the open part of the southern Barents Sea, both scientific, shallow stratigraphic wells, and commercial exploratory wells.

Literature also reveals some data from drilling carried out in the Russian Barents. Seismic data acquired in 2011 and 2012 and other geological data from the Barents provide a good basis for estimating the undiscovered petroleum resources in the southeastern Barents, NPD said.

In the opened part of the Barents Sea and the northern Barents Sea, the expected figure for undiscovered resources is 960 million standard cu m of oil equivalent, or 37% of the undiscovered resource on the Norwegian Shelf.

NPD said, “The new resource estimates for the southeastern Barents Sea increase the estimate of total undiscovered resources in the area by about one-third and strengthen the Barents Sea’s significance for Norwegian petroleum activities.”

The northeastern Barents Sea, which is also part of the new Norwegian Sea area, is almost as large as the southern part. The NPD acquired seismic data there in summer 2012 and will continue in 2013. The resource figure from this area will further increase the estimate of the undiscovered resource.

Meanwhile, seismic and aeromagnetic data and numerous source rock samples have been acquired in recent years in parts of the 100 000 sq km area that may be opened around Jan Mayen Island. Considerable uncertainty surrounds the area’s potential compared with the southeastern Barents due to the lack of drilling around Jan Mayen.

NPD estimated the expected resource in the Jan Mayen area at 90 million standard cu m of oil equivalent with a possible considerable upside of as much as 460 million standard cu m, but it said the lower end of the estimates indicate that it is uncertain whether any hydrocarbons will be found.

Uncertainty could be reduced if a discovery were made. The expected resource in the area will increase to 200 million standard cu m with an upside of 640 million standard cu m and a downside of 20 million standard cu m.

The sea areas surrounding Jan Mayen are included in the opening process border with the Greenlandic shelf to the west and the Icelandic shelf to the south. Geologically, the Jan Mayen area consists of the volcanic island Jan Mayen and the subsea Jan Mayen ridge that runs southward from the island. The Jan Mayen Ridge is surrounded by oceanic crust which was formed as the North Atlantic Sea opened up.

The process of forming a new oceanic crust started in the area about 55 million years ago and is still taking place, NPD said. This was how the Jan Mayen ridge was separated from Norway and Greenland and remained out in the ocean as a microcontinent. The Jan Mayen ridge is therefore expected to consist of the same continental and marine rocks that can be found in eastern Greenland and on the Norwegian shelf in the Norwegian Sea, with possible oil and gas potential.

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.
