NDP Annual Report 2014

February 2015

NorwegianDeepwaterProgrammeNDP - History

NDP was established in 1996 when the first deepwater licenses were awarded (15th

Concession Round) in the Norwegian Sea. New licenses have been awarded in all

following concession rounds, the latest 22nd round licenses awarded in 2013.

The programme phases are Phase 1 (1996-2000), Phase 2 (2001-2005), Phase 3

(2006-2008), Phase 4 (2009-2012) and Phase 5 (2013-2016). Project investment since

the start is approximately NOK 400 millions. Last years budgets have been around

NOK 20 millions.

NDP covers mainly an area between 62°N and 69°N, from the continental shelf at 400 m water depth to the abyssal plain at approximately 2500 m. In Phase 4 the deepwater slope area west of the Barents Sea was included in NDP. The area comprises therefore all deepwater provinces in Norwegian waters. Metocean modeling covers a much wider area, from the Atlantic west of Ireland, the North Sea and the Barents Sea.

In order to achieve objectives for Phase 5 and the time beyond, a strategy discussion started in 2013. A plan for needs and opportunities will be finished early 2014.

All NDP results are stored in License2Share, the official communication and archiving tool for administrative interaction between operators, partners and authorities for all licenses in Norwegian waters.

• Important part of getting permission to explore and develop licenses is to have thorough understanding to avoid harming marine life.

NorwegianDeepwaterProgrammeMetocean Project (1)

Objective

To establish metocean conditions and databases for use in deepwater operations and design of installations by:

• Acquisition of ocean current data

• Modeling and establishment of

hindcast for currents and waves

NoSH area

Surface speed 2013-10-07 at 10 UTCROMS – 4 km horizontal resolution


Benefits to licenses

NORA10 – wind and wave hindcast: The database contains high quality wave and wind data in 10 km resolution from West of Ireland to the Arctic for the period 1957 to 2013. Data are used for planning purposes of both exploration and field development. Current Verification Study: ADCP data collected in the uppermost 50 m is noisy, especially during periods with significant wave height above 3-4 m. It is important to further investigate this in order to give recommendations to improve quality for future measurements programs. Norwegian Sea Hindcast: The new hindcast for the Norwegian Sea will together with measurements contribute to give a better understanding of the currents during extreme weather.

Long-term ( ̴30 years) nested ROMS hindcast successfully completed for framed area in 4 km grid. This grid is sufficient to provide good statistics regarding currents and current strenght

NorwegianDeepwaterProgrammeSeabed Project (1)

Objective

To improve the regional and local understanding of hazards, the geotechnical challenges and other related processes and features on the seabed and in shallow sediments in different environmental settings.

An integrated approach to assess the safety and feasibility of exploration activities and field developments with regards to:

• Slope stability

• Drilling problems

• Geo-hazards



• Modeling slope stability to arrive at a novel, integrated work flow for soil investigations and landslide hazard assessment, utilising geophysical, geochemical, geological and geotechnical data



• Technology review and design guidance document for a novel foundation solution for deepwater developments that are designed to slide directly on the seabed

• Digitisation of analogue sparker records on the Norwegian shelf to ensure preservation of information

• Improved understanding of gas ex-solution and sample cracking that has been observed in samples recovered during deepwater geotechnical investigations



• Improved understanding of soil behaviour in deepwater where seabed temperature may be close to zero degrees and samples recovered may suffer disturbance as a result of pressure relief

• Guidance on novel foundation solution options for deepwater developments

• Ensuring accessibility of available analogue records in the future and simplification of access through digitisation

• Improved, integrated approach which results in better understanding of the environmental processes leading to landslides

NorwegianDeepwaterProgrammeSubsea Project (1)

Objective

• To develop low cost subsea technology concepts, methods and procedures for installation and operation of subsea systems in deep waters.

• To make operators, suppliers and contractors aware of the challenges for future field developments in deep water areas in the Norwegian Sea.

• To contribute to improved hydrate control concepts and solutions.

Subsea Project (2)

Environmentally friendly kinetic hydrate inhibitor

• A new environmentally-friendly Kinetic Hydrate Inhibitor (KHI) from fish waste protein has been developed. This is effective at low temperatures. It can also be added to MEG to reduce the required MEG volume typically up to 50%

• An operating window for the chemical has been established (including its sensitivity to pH, pressure and synergism with MEG).

KHI removal

• New chemicals have been developed to remove KineticHydrate Inhibitor (KHI) polymers from produced water.They have low toxicity, good biodegradability and showremoval efficiencies up to 99% depending on the KHItype.

• The efficiency of KHI removal on selected green KHI´s isnot improved by temperature and it is reduced upon theaddition of MEG.

Subsea Project (3)

Hydrate monitoring

• Broad-band permittivity sensor systems using

open-ended coaxial probes were adapted to

Statoil’s HP and to SINTEF’s rotating pipe rig/cell

to measure hydrate formation with gradual

build-up of hydrates on the pipe wall.

• Data shows that formation of hydrate layers as

thinner than 1 mm can be detected. In addition,

differences in responses with respect to hydrate

porosity, water trapped within the hydrate layer,

are also detectable

• Access to a new measurement technology for characterization of hydrate

• Greener chemicals available for usage

• Reduced chemical usage

• More time available for corrective operational measures rather than focusing on hydrate control measures
