This paper presents the effects of a planned CO2 injection on fault stability at Tomakomai offshore, Hokkaido, Japan. Using slip tendency scheme, the artesian reservoir is estimated to be naturally at moderate slip level around 0.5 at assumed faults optimally oriented for slip. The analysis results indicate that the planned injection has limited effects on fault stability at the site and the increased slip tendency is unlikely to be "ready-to-slip". However, the attention is required at the vicinity of the injection point as well as the far pre-existing fault where would be the slippiest due to the high background value.
