Aide Memoir for Geophysical Risk AssessorsIAGC/OGP Workshop

September 2007

E. Sixma – SIEP

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!

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?

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

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.

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”

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

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.
