Agenda

■ Field Architecture and Flow Assurance

■ Equipment, Disciplines and Flow Assurance

■ Holistic Field Architecture Development

■ Trends

● Faster and cheaper

● New developments in mature areas

● Longer and deeper

■ High Tech

What is Flow Assurance?

”Transporting the fluid from well to facility with low risk”

How?

● Defining field architecture

● Sizing flowlines and pipelines

● Selecting hydrate strategy

● Selecting wax strategy

●

Managing liquid & slugging

● Solutions for life-of-field

– including boosting

Corrosion protection

Electrical cable

Steel pipe

Thermal insulation

The field architecture can be complex .....

....or more standard




Confidential

Flow Assurance

.... but it must always be based on flow assurance:

- Capacity for peak production

- Operability for tail end and turndown- Acceptable margins and operability with respect to hydrates

- Acceptable margins and operability with respect to wax

- Acceptable corrosion protection over life-of-field- Acceptable erosion protection over life-of-field

- Shut-down and start-up

- Mitigation options in case of unwanted incidents (hydrate plugs,sandscreen failure, gelling, ...)

Example – Flow Assurance and Pipeline Routing

■ Flow Assurance shouldalways be involved inpipeline routing.

■ It may be possible to

find a routing that is better from a slugging and liquidmanagement perspectivewithout increasing the cost

Slide 11

Drivers of future field developments

Deeper waters,complex

reservoirs, harsh

environment

Drive forincreased oil

recovery from

existing fields

Longer subseastep-outs (distance

from well to

process facility)

Reduce costs todrive marginal

developments

The ” faster and cheaper” trend

■ It all comes down to cost and schedule

● Fast track – standardization

● Qualified dimensions

● Standard spec (10 K, class U+, 22 CrP, ...)● What can be delivered?

● What can be installed? Flexible flowlines?

● High activity – target schedule robustness

● Being aware of cost steps

Confidential




Confidential

Can we manage with only proven technology?

■ Fast track can not be combined with qualification programs

Confidential




Confidential

The ” mature area” trend

■ Tie-back to existing facilities● Limited Flow Assurance options – less conservative strategies

● Risers■ Pre-installed existing

■

J-tubes – or risers as J-tubes■ Retrofit caissons with risers

■ Flexibles from new modules

● Slug handling

● Split of production to several hosts■ Subsea separation

● Supply of ”utilities” from several hosts

● ”No” area or weight reserves■ Tie-in to existing subsea infrastructure

● Routing limitations● Adaption to existing FA philosophies

● Pressure protection (subsea HIPPS / IOPPS)

Confidential




Confidential

The ” longer and deeper” trend

■ The oil provinces are going deeper and deeper ● Subsea boosting

● Subsea separation

● Combined solutions with riserbase separation/pumping designed

to fit minimized topside solutions

■ The gas provinces are going longer and longer

●

Subsea compression is emerging● Liquid management is becoming less conservative

● Long distance power transfer and subsea power distribution isqualified
