Removal, Decontamination, Treatment and Disposal of NORM 

Sureclean have developed the appropriate safe operating procedures and local rules encompassing the necessary methodology and controls to undertake NORM removal and/or decontamination, treatment and disposal operations.

Removal and Decontamination of NORM

NORM contaminated equipment requires to be cleaned efficiently to either reduce or remove the NORM residue to a minimum level (ALARP). Using our specialist technology and trained operatives, Sureclean will safely remove scale build ups / deposits from downhole and topside process equipment including tubulars, pipe work, valves, spools, tanks and vessels, decontaminating them to natural background levels. The standard accepted industry practice for NORM removal is HP and UHP water jetting which is a proven cost effective and efficient method for the removal of scale, sand, wax and sludge.

Treatment and Disposal

The disposal option determines whether or not, upon removal the NORM contaminants shall be treated. Disposal options are limited and depend on the location of the NORM decontamination operations. Accepted disposal routes are;

  • Disposal to Sea (subject to the appropriate authorisation)
  • Re-injection (plugged / abandoned well, depleted reservoir)
  • Encapsulation for long-term storage in a licensed depository

Prior to disposal to sea or disposal by re-injection, oil contaminants are removed from the NORM material to levels as low as reasonably practical (ALARP) and then macerated using specialist equipment to a particle size of 1000 microns or less prior to disposal.

Water used in the cleaning and/or decontamination process can be minimised by containment and reuse of all washings using filtration.

Alternative Treatment and Disposal

The chemical treatment of NORM and the potential to export the waste are examples of alternative options currently being evaluated by Sureclean together with associate organisations.
