Corrosion threat assessment of crude oil flow lines using Bayesian network model

Abstract: Abu Dhabi Company for Onshore Oil Operations operates multiple carbon steel oil flow lines, which are emplaced on the desert surface of Abu Dhabi. The company's main oil pipelines are buried with coating and cathodic protection and internally protected by chemical inhibition, but the flow lines are without coating and cathodic protection. Over the years, this approach has been successful for flow lines, but the frequency of corrosion related leaks has increased recently due to changing operating and external conditions. This paper describes the use of a Bayesian network model that combines physics based models and expert knowledge of the flow lines to predict corrosion flaws depth and leak probability. It is shown that the Bayesian network approach can be useful in estimating location specific probability of failure and thus providing input to the prioritisation of inspections and corrosion mitigation. The approach was validated for five selected flow lines, where detailed field examination was av...

Report on the SEG/KOC joint workshop in Kuwait: Seismic multiples — Are they signal or noise?

Abstract: In December 2014, SEG and Kuwait Oil Company (KOC) held a joint workshop in Kuwait City to advance the understanding of seismic multiples and to provide answers to the question posed in the title of the workshop, “Seismic multiples — Are they signal or noise?” Indeed, despite recent advances in the prediction of multiples as noise and in their imaging as signal, the processing of multiples in seismic data remains a major challenge for the industry.
