SmithAndrewRisk Management Systems Ltd.Director – Risk (HSSE & SR & SD) Management Consultantdrandrewlsmith@dsl.pipex.comUKKemnayDr. Smith’s seminal paper „Radioactive Scale Formation“ was presented to the RSC in Manchester, UK; at the OTC in 1985 and published in JPT June 1987. During the 1980’s he developed the original Low Specific Activity Radioactive Scale [NORM] radiological standards and procedures within the UKCS.   He prepared a Briefing Note on NORM submitted to the UK House of Lord’s enquiry on the Decommissioning of Oil & Gas Installations, 1995/6. The IAEA has acknowledged that his review made a most valuable contribution to the development of Safety Reports Series No. 34, „Radiation Protection and Management of Radioactive Waste in the Oil and Gas Industry“, 2003. An October 2008 Louisiana Court highlighted that his JPT June 1987 paper contributed to the body of scientific literature by demonstrating the first correlation between API GR units and radiological dose. Prior to this the oil & gas industry had not recognized the potential topside health concerns from radioactive scale in tubulars. He recently presented SPE 125661 on NORM: The Lessons to be Learned, New Challenges and Innovative Thinking with Decommissioning and Radioactive Waste at the 10th SPE HSE Int’l Conf in Oil & Gas E&P, Rio de Janeiro, Brazil, April 2010. He has been retained as an oil & gas industry litigation consultant with particular expertise on NORM and is the SPE Distinguished Lecturer on HSE (NORM) for the 2010 / 11 season.
