Uncertainty analysis of borehole stability problems Conference Paper uri icon

abstract

  • An uncertainty analysis is conducted for borehole stability problems based on a statistical error analysis method. The uncertainty analysis shows that the parameters impacting on the safe mud weight to stabilize borehole are rock strength followed by shale swelling, in-situ stress, pore pressure, well inclination, and so on. Several procedures to improve borehole stability analysis are proposed.
