5. OPEN FRACTURES – DEPI #5834 (FAULT ZONE)
Highly deformed interval
Strike: NNE – SSW
Dips: °
The strike of the open fractures is basically NNE – SSW. Now why is this important?

6. DRILLING INDUCED FRACTURES – DEPI #5834
Strike: ENE – WNW
Dips: (high) NNW - SSE
DIF’s orient themselves parallel to the present-day most compressive stress.
