This Lecture discussed an overview of how rock mechanics can be applied to analyse well stability problems. Geomechanical information is relevant to assure wellbore stability, i.e., to prevent damages in the formation and later on, the casing and therefore the importance of the lecture. It covers Unstable boreholes - reasons and consequences, The principle of a stability analysis, calculation of minimum mudweight required to prevent borehole collapse, Calculation of maximum mudweight before fracturing, Example Calculation, Evaluation of the method and the results, Other aspects of practical importance. |
