    • A mesocoms experiment on the impacts of water- and olefin-based drill cuttings on benthic communities 

      Schaanning, M.; Trannum, H.; Øxnevad, S. (NIVA-rapport;5342, Research report, 2007)
      A three months simulated seabed experiment on water- and olefin-based drill cuttings has been performed at NIVAs Marine Research Station at Solbergstrand. Twelve box-core samples were transferred from 200 m depth in the ...

      Schaanning, M.; Ruus, A.; Bakke, T.; Hylland, Ketil; Olsgard, Frode (NIVA-rapport;4571, Research report, 2002)
      Experimental work on uptake of metals from sediments spiked with barite, ilmenite and hematite were performed using the ragworm Nereis diversicolor and the netted dog whelk Hinia (Nassarius) reticulata as test organisms. ...

    • Trace metal mobility and faunal effects of weight materials in water-based drilling muds 

      Schaanning, M.; Trannum, H.; Holth, T.; Øxnevad, S. (NIVA-rapport;5680, Research report, 2009)
      Ilmenite and barite minerals are alternative weight materials in water-based drilling muds for off-shore drilling operations. After use mud remnants may be discharged from the platforms and end up in cuttings deposits on ...
