Gulf of Mexico HP/HT Well Design

Challenge:
High-pressure/high-temperature (HP/HT) well with:

• Pore pressure gradient: 0.92 psi/ft

• Bottomhole temp: 410°F

• History of casing collapses in the field

Solution:

• Geomechanical modeling to optimize mud weights

• Expandable liner design for weak zones

• Real-time PPFG monitoring while drilling

Results:
✓ Zero well control incidents
✓ Drilled to TD 14 days ahead of schedule
✓ Saved $4.3M in contingency costs
