WellMaster:
Industry Reliability Database for Well Completion Equipment
Objective
”To obtain continuous improvement in the reliability of well completions through collection, analysis and sharing of reliability data for the well completion equipment.”
Value Proposition - WellMaster
Best available decision support data for well reliability and risk problems:
Best available reliability data on well equipment world-wide -accepted as industry norm
Access to most advanced Expert Services
Full insight into reliability of own wells and highly representative industry wide data for benchmarking purposes
Combined use of WellMaster Data and risk assessments are key to informed decisions on well intervention issues, well lifetime extensions following malfunctions and deterioration of well barriers

WellMaster Success Stories
Bjørn Skårdal, Well Intervention Supervisor, ConocoPhillips 01.02.2008:
“ConocoPhillips Norway have over the years utilized the analytical services of ExproSoft and the contents of their generic WellMaster database to conduct risk assessments that have enabled us to oppose Norwegian Authorities with confidence, reverse unfortunate legislation and improve our overall understanding of the risk associated with our business. Another attractive side-effect of these studies has also been huge savings (several hundred million USD over the past 15 years)”

Reliability Data – What is It?
Exposure data: Service time
Stressors/environmental data (pressure, temperature, CO2, H2S) etc
Equipment inventory data (item, manufacturer, model designation, size, etc)
Failure Data:.
Failed item/date of failure
Failure Mode
Failure Effect (initial, consequential failure)
Suspected Cause of Failure
Information on Repair/Remedial Action
Root Cause Failure Analysis(RCFA)
Increasing value of data
