Background information and definitions
Fluids used in the drilling process, also called “muds” are often contaminated with oil and chemical additives causing pollution in the area (Henry et al. 2017). These fluids could be reused or recycled, potentially reducing the cumulative risk to subtidal benthic invertebrates through reducing a source of pollution (Loan et al. 2018). Additional evidence related to drilling fluids are summarised under “Threat: Energy production and mining – Use water-based muds instead of oil-based muds (drilling fluids) in the drilling process”.
