WIN WIN - Wind-powered water injection Assessing a new concept for water injection, utilizing wind power

7

WIN WIN is a concept for a new generation of oil recovery technology currently being assessed. It comprises a floating wind turbine which supplies power to a water injection process. The concept is a fully stand-alone system that includes pumps and basic water treatment. Our ambition is that WIN WIN will reduce costs, increase flexibility, and reduce emissions.

In 2015/2016 assessment

• Statoils Hywind demonstrator, a floating wind turbine located offshore

Stavanger, Norway, has been operating since 2009. In the record year of

2011 it produced 10.1 GWh.

• The potential for moving the test unit to the Valemon platform has been

assessed by statoil.

• Valemon is today supported by power from the Kvitebjørn platform, 10

km away

• From being able to shut down one of the two gas tubines, a reduction

of 11000 tons of CO2 could be a achieved, with associated costs.

The base case configuration and its functionality

30

1. A standard wind turbine is mounted to a floating foundation. This foundation also serves as a platform for the water injection system.

2. An electrical micro grid enables controlled start-up and shut-down of the system, and ensures that power demand matches power supply during operation. A battery bank ensures power to critical safety and communication functions during periods of no wind.

3. Communication with the host platform is enabled through satellite communication. A conventional control umbilical can also be used.

4. The system uses sea water, which is pumped topside using lift pumps.

5. The sea water is filtered down to 50 micron using a vertical disc filter with backwashing capability.

6. The water is treated with chemicals. Chemicals are stored on board in vessels, and refilled during other maintenance activities on the platform.

7. Water is injected into the reservoir by injection pumps.

Performance of WIN WIN

The WIN WIN concept has shown that it can

meet the demands in relation to set

requirements

Key performance issues addressed in the project

include delivering required injection volumes,

understanding overall availability as well as

investigating start-stop cycles and downtime.

For the use case considered and others, WIN

WIN exceeds target injection rates over time.

Injection volumes over time have been simulated

based on realistic wind-data for the use case,

showing that volumes exceed target rate, despite

some periods of low wind.

31

DNV GL © 2016 15 June 2016

Commercial - CAPEX

Total CAPEX for the use case configuration with

process equipment located topside comes to around

75 MEUR.

The wind structure and marine operations and

logistics are the two main CAPEX drivers, together

contributing to more than 50% of CAPEX costs.

The pump system and development costs are also

significant in the overall investment.

32

DNV GL © 2016 15 June 2016

Commercial - OPEX

To achieve a realistic estimate of the O&M cost and

performance, DNV GL has modelled the system taking into

account failure rates, repair times and wind and wave data.

The resulting annual average operation and maintenance

costs are on the order of 4,7 MEUR.

Key drivers include parts, chemicals, and vessel costs.

Increased reliability of the system would positively influence

maintenance frequency and scope, in particular for

unscheduled maintenance, reducing operational

expenditures.

33

DNV GL © 2016 15 June 2016

The use case costs have been compared with a

conventional alternative where water injection is

accomplished with a flowline from the host.

While WIN WIN has higher operational

expenditures compared to a conventional

alternative, the significantly lower capital

expenditure means that it comes out comparable

in 20 year life-cycle comparison.

WIN WIN is therefore a commercially competitive

alternative in a range of cases, and especially

when host platform capacity is limited or injection

wells are located far away.

An innovation project now entering a second Phase

40

In the phase 1 of the WIN WIN project a technical and commercial feasibility assessment was conducted with successful results. DNV GL and its joint industry partners have now started a phase 2 to drive the concept further towards commercialization by maturing the technical solutions, reducing uncertainty and cost, and enhancing performance.

The objective for Phase 2 is to develop the WIN WIN concept towards commercialization. The project will overall on the four following pathways:

Phase 2 - Objectives Phase 1 - Benefits

Feasible: The concept is, to a large extent, based on commercially

off-the shelf components and systems. Many of the remaining parts

are already undergoing full-scale testing.

Effective: WIN WIN meets performance requirements for a wide

range of injection volumes and several reservoir types.

Competitive: The concept can be cost-competitive, especially

when the host platform capacity is limited or the injection well is

located far away.

Emission: Potential to reduce emissions, reduce carbon tax, from

reduced need of operating gas turbines.

Flexible: The inherent flexibility of the WIN WIN concept means

that more water injection locations can be targeted through easy

relocation, regardless of distance to platform.

Innovative: Building on the strength of two industries, oil and gas

joins forces with wind to achieve something greater together, also

enabling a faster commercialization of floating wind turbine

technology

Validate: Build confidence and reduce uncertainty in the technical

solution developed in Phase 1

Innovate: Improve performance and competitiveness

Recommend: Develop guidelines for the design and operation of

WIN WIN

Explore: Identify other applications where wind power can provide

a cost effective solution
