Statoil matures reserves in Norway through improved recovery

Jan 18, 2012 12:00 AM

Statoil has matured more reserves through improved recovery than the Skrugard and Havis discoveries combined in 2011. The company is now strengthening its focus on improved recovery.
“2011 will always be remembered for the major finds on the Norwegian Continental Shelf (NCS), while at the same time we have completed a great year with regard to improved recovery. We have matured more volumes through improved recovery efforts than the Skrugard and Havis finds combined,” says Øystein Michelsen, executive vice president for the NCS.

Statoil delivered six plans for development and production and matured around 560 mm boe Statoil shares for the large NCS projects during 2011. Of these volumes 420 mm boe are the result of improved recovery alone.
“Statoil's main improved recovery projects in 2011 were Troll 3 & 4 compressors and Åsgard subsea gas compression,” says Michelsen. ”They accounted for 350 mm boe in improved recovery alone for Statoil. In addition we have the volumes resulting from our drilling and well activities and improved recovery from small and large modification projects on our NCS installations.”

The total investments on Troll and Åsgard subsea compression amount to NOK 26 bn.
“Åsgard subsea gas compression will be the world's first subsea compressor and is a good example of how pioneering technology can help extend the life of our existing NCS fields. We want more technology breakthroughs and is stepping up our technology effort,” says Siri Espedal Kindem, Statoil's head of technology.

Statoil's research activities have been increased by 27 % and will amount to NOK 2.8 bn in 2012.
Furthermore the company plans to expand the research centre at Rotvoll in Trondheim to accommodate the largest improved recovery centre in Norway.

Improved recovery is also key in Statoil's new technology strategy in which four prioritised technology areas have been identified:

  • Seismic imaging and interpretation
  • Reservoir characterisation and recovery
  • Drilling and well construction
  • Subsea production and processing

“Technology for better reservoir understanding can alone add reserves of 1.5 bn boe to our global portfolio by 2020. In addition we will focus on technology that will reduce drilling time by 30 % and drilling costs by 15 % by 2020."
"If we succeed in developing a subsea factory, it will lead to improved recovery, reduced costs and lower energy consumption in the further development of the NCS,” says Kindem.

Market Research

The International Affairs Institute (IAI) and OCP Policy Center recently launched a new book: The Future of Natural Gas. Markets and Geopolitics.


The book is an in-depth analysis of some of the fastest moving gas markets, attempting to define the trends of a resource that will have a decisive role in shaping the global economy and modelling the geopolitical dynamics in the next decades.

Some of the top scholars in the energy sector have contributed to this volume such as Gonzalo Escribano, Director Energy and Climate Change Programme, Elcano Royal Institute, Madrid, Coby van der Linde, Director Clingendael International Energy Programme, The Hague and Houda Ben Jannet Allal, General Director Observatoire Méditerranéen de l’Energie (OME), Paris.
