Workcard generated from the catalogue
What this topic covers
Control, treatment, storage, transfer and disposal of hazardous and special oilfield waste generated by drilling, completion, testing, subsea, workshop and decommissioning services.
How it shows up in this industry
Drilling fluids plants, shale shakers, centrifuges, cuttings dryers, well testing scopes, workshops, vessels, decommissioning support and reverse logistics generate used mud, drill cuttings, oily residues, spent filters, scrap tubulars, contaminated equipment and NORM scale requiring specialised handling and disposal.
Why it may be material
Waste handling and NORM management are inherent to drilling fluids, solids control, intervention, testing, decommissioning and backload operations. Failures can generate clean-up liabilities, disposal bottlenecks, regulatory penalties and loss of operator confidence.
Impact pathway
- Potential effects may reach workers.
- Potential effects may reach contractors.
- Potential effects may reach supply-chain workers.
- Potential effects may reach affected communities.
- Potential effects may reach water bodies.
- Potential effects may reach soil and groundwater.
- Potential effects may reach ecosystems.
- Affected stakeholder groups identified in the source include Affected communities, Contractors, Customers / end-users, Employees, Value chain workers.
- The source places the pathway in Own operations, Downstream, Cross value chain.
Financial pathway
- The topic may change operating costs through resource use, controls, remediation or ongoing management.
- The topic may create provisions, penalties, remediation costs, claims or other liabilities.
- The topic may affect demand, pricing, market access or product and service revenue.
- The topic may affect reputation, licences to operate, intellectual property or other intangible value.
Questions to test
- What evidence supports both the impact and financial materiality pathways?
- Which own operations, assets or decisions create or concentrate the pathway?
- Which products, services, customers or end uses create or concentrate the pathway?
- Where across the value chain is the pathway most significant?
- What is the scale, scope, likelihood and remediability of effects on workers?
- What current or proposed regulation could change the topic's relevance?

It may be less material when…
- Organisation-specific evidence does not support significant scale, severity, likelihood or financial effect.
- The organisation has no meaningful exposure to or influence over the relevant downstream pathway.
