Session #8

Oil and Gas Perspective – Waste

Slide 3

•  Fragmented: defined as an inherent material resulting from operations to be eliminated, reused, recycled or recovered including office and commercial activity

•  Regulated: hazardous waste components •  Selective: narrow in scope •  Historically waste is not a design consideration and

does not indicate good or efficient design

Session #8

How Do We Move from Linear to Circular?

Slide 4

Session #8

Oil and Gas Perspective – Perceptions & Barriers for Adopting Circular Practices

Slide 5

•  Preference for buying new •  Non standard build of assets - custom equipment •  Risk of reusing material on oil and gas assets

–  Health and safety –  Condition of equipment and products –  Insurance concerns

•  Few industry precedents •  Environmental remediation and disposal costs can exceed

construction cost

Session #8

Actual Barriers to Circular Economy

Slide 6

•  Suitability of materials for reuse •  Marketplaces to facilitate reuse and recycling •  Information barriers

–  Sectors work in silos •  Organizational/cultural obstacles •  Institutional barriers

– Fiscal and regulatory

Session #8

Closing the Loop: Redesign for Reuse, Remanufacturing and Recycling

Slide 7

•  Engage value chain stakeholders •  Substitute materials

–  eg. in hydraulic fracking, liquified CO2 for water •  Use standard parts •  Apply technologies like “digital twinning” •  Design facilities and equipment for ease of

maintenance, upgrade and reuse at FEED - Front End Engineering Design

Session #8

Closing the Loop: Redesign for Reuse, Remanufacturing and Recycling

Slide 8

•  Assets are industrial nutrients •  Design for entire value chain synergies, especially

handoffs between segments •  Leverage synergies and integrate with other industries

that place a value on oil and gas industry outputs •  Steward all resources including human factors,

community and the environment

Slide 10

•  Identify “low hanging fruit” •  Map where you are in the maturity progression •  Understand capabilities needed to achieve goals •  Begin engaging with / creating “enhanced” value chain •  Create realistic timelines
