Sažetak
Exploration and production as one of the most important parts of the petroleum industry encounters different problems, usually resulting in nonproductive time and additional expenses. Probable the most common and most expensive of them are probably related to wellbore instability and associate problems. Wellbore instability problems are usually related to drilling operation, but they can also appear during completion, workover or the production stage of a certain well. The traditional solution for wellbore instability problems is composed from the early recognition of specific wellbore instability problems, the main cause identification and swift response. For more effective solution it is necessary to incorporate wellbore stability and risk assessment in the early phase of well design. This chapter gives one general overview of wellbore instability problems and their cause as well as an overview of actual approaches and methods in wellbore stability and risk assessment.
