Case Study
MAX-BRIDGE bridging solution improved wellbore stability on historically troublesome wells
Jun 23, 2020
Overview
Challenges
- Historically troublesome 12 1⁄4-in. section
- Highly depleted formation
- Wellbore instability
- Unsuccessful attempts with several LCM applications
Results
- Reduced downhole losses from an average of 2,200 bbl per 12 1⁄4-in. section to zero losses
- Decreased overall NPT by eliminating differential sticking and decreasing drilling torque
- Increased wellbore stability by allowing higher fluids density up to 0.4 ppg
Case study details
In a mature field in East Kalimantan, Indonesia, an independent operator experienced massive losses in a
series of wells, along with wellbore instability-related problems. The extremely low pore pressure typically found in these types of mature fields is problematic because the low pressure requires having enough drilling fluid density to stabilize the wellbore.
