IKATANAH
LIGEOLOGI IN
DONESIA
Course objectives
1. Understanding the concept of subsurface pressure and stress
2. Apply ‘suitable’ method to estimate overpressure
3. Apply overpressure concept to operation (drilling) and exploration activities
Course agenda
• Day 1: Introduction and familiarization to subsurface pressure and stress
• Day 2: Overpressure generating mechanism
• Day 3: Overpressure estimation method
Course agenda
• Day 4: Application of overpressure– Pre-drill overpressure estimation– Geological application
• Day 5 (half day): Case study of overpressure in some Indonesia’s sedimentary basins and worldwide
