  1. Aide Memoir for Geophysical Risk Assessors IAGC/OGP Workshop September 2007 E. Sixma – SIEP Seismic 1 RTA 20/8/2005

  2. Introduction - 1 • Risk Assessment and the use of a Risk Assessment Matrix (RAM) require a memory function. • Risk assessment for low frequency, high potential incidents (Fatalities) needs to be done on the basis of collective industry experience. • Need a repository for Industry experience. “Aide Memoir for Geophysical Risk Assessors” • Proposed to April 2006 HSE forum and agreed action. • Work in progress, further contributions invited!

  3. Introduction - 2 • Prime objective • Tutorial for next generation (“mandatory reading material”) • Avoid repeats and re-inventing the wheel the hard way ! • Reference database for use with RAM, capturing industry experience • Answer the question “Has this happened in the industry ?” • Side benefits • Improve statistical insight • Identify “Rare” but real risks • Further use • Cross check when developing guidelines, e.g. OGP 317 and IAGC HSE manuals • Have we covered all known risks that have resulted in a fatality in the past?

  4. Data base content and structure • Excel spreadsheet • Sort and Search functionality • Graphical analysis tools • Fields used: • Record number for reference (invariant to sorting) • Year • Number of fatalities in event • Single or Multiple (>3) fatality • Summary accident description • Comments, identified root causes if available • Geophysical or Other operation • Land / TZ / Marine • Type of accident, broad standard classification • Type of accident, more detailed classification • 3 Keyword fields

  5. Data base content and structure • Not included • High potential Near Misses • Common vehicle accidents • Limit size and effort, but may be we should add these too ? • Country (exception: bee attacks) • Company or Contractor information • Information about victims, such as gender, age, time employed etc.

  6. Data base sources • OGP annual reports since 1980 • IAGC and CAGC data and HSE alerts • STEP change Sadie database alerts • WesternGeco • CGG • Many experienced individuals • Reports “from memory” accepted from reliable sources • All fatal accidents in Geophysics that we could find (except vehicle accidents) • Relevant accidents from other E&P operations that “could easily have happened in Geophysical Operations”

  7. Data base • So far captured: • Geophysical operations: • 379 fatalities from 219 accidents • Other • 217 fatalities from 181 accidents • Please contribute and send info on further fatal incidents, not yet in the data base, to E. Sixma (Eelco.Sixma@shell.com) • Plan to “package” data base with some introductory and explanatory text and to publish as OGP report towards the end of 2007. • Excel data base will also remain available through OGP / IAGC websites. • Update database yearly

  8. Graphical analysis • Courtesy Michael Denkl, WesternGeco • Pivot Charts • By type of accident • “Zoom in” on some classes of accidents, e.g. Drowning • By year • Can select on • Number of Fat. and S/M: Single / Multiple • A/G/O All, Geophysical or Other • Type of operation Land / TZ / Marine • Note: pivot charts “skip” years in which no event is recorded, slightly impairs visual analysis.
