Distinguished lecture by John Thorogood, Drilling Global Consultant LLP.
This presentation reviews the events leading up to the Macondo loss of well control and it offers an alternative interpretation based on ambiguities inherent in the data to suggest how the resulting decision could have appeared logical given the series of cues with which the crew was presented.
A brief background is provided to some of the key psychological concepts related to the incident, including risk aversion as well as other biases that can influence teams in similar situation. Comparisons are made with accounts of other well control incidents available in the public domain and a cross check on wheater similar influences could have played a part elsewhere. Analysis of Macondo and other similar incidents highlights the general rule that when there is ambiguous information and the potential for multiple interpretation, a natural tendency is to choose the least threatening scenario.
