Abstract

This paper presents results of analysis of changes in stress state and fault stability related to a planned geological CO₂ injection at the Tomakomai offshore site, Hokkaido, Japan. Predicted slip tendency in shallow Moebetsu formations is much lower than that in deep overpressured Takinoue formations, and estimated effects of the planned injection are relatively limited in both formations. Another point is that poro-elastic stress development leads to changes in fault stability compared to that calculated based on pressure buildup alone and the initial stress state. These poro-elastic effects on fault stability are comparable to those due to pressure buildup itself.
