摘要：

This paper presents an integrated analysis of borehole instability problems in the seismically active Gulf of Alaska. A well-documented instance of borehole collapse from one well is used to calculate horizontal stresses. For the Gulf of Alaska, horizontal earth stresses were very high and appear to have contributed to the occurrence of abnormal pore pressures and borehole instability.
