Table 5 Mandatory aspects in designing geothermal well in Field Dieng
From: Casing failure identification of long-abandoned geothermal wells in Field Dieng, Indonesia
No. | Flow paths of wellbore drilling design and integrity based on common SOP and best engineering practice | Mandatory |
|---|---|---|
1. | Casing setting depth—Philippines’ method (temperature 220 °C, fluid is water dominant) | ✓ |
2. | Casing design—strength correction due to high thermal effect | ✓ |
3. | Casing grade selection with high thermal effect consideration | ✓ |
4. | Proper data storage and management | ✓ |
5. | Proper directional drilling design and operational | ✓ |
