Key Messages
• The Technology development and
focused reservoir learnings early in the development are keys to success in
Lower Tertiary
• Long-term relationships and
collaboration with Service Providers
and Co-owners enabled technology
• Robust design and reliable operations
are paying dividends
• Favorable early-time performance, but
still many learnings ahead

Efficient CompletionsSingle-trip Multizone Frac Pack Technology
• High production rates enabled by frac pack completion
• Thick oil sand intervals require
three to five frac packs for effective stimulation
• Reservoir pressures, interval lengths, and completion design
require improved perforating
gun to survive downhole
conditions
• In a five zone completion,
Single-trip Multizone technology
saves 10 trips in the hole and reduces completion time by ~28 days per well
Conventional Completion (5 zone)
� 14 trips for completion installations
including five perforation runs
� 64 days for sandface completion
ESTMZTM* System Completion (5 zone)
� 4 trips for completion installations including one
perforation run
� 36 days for sandface completion

Seafloor BoostingIncreases Recovery and Improves Flow Rates
Artificial lift challenges:
� Improve production profiles by lowering wellhead pressure
� Enable long tie back distance
� Reliability of electric submersible pumps and fluid compatibility for gas lift
Design competition strategy:
� Extend water depth and power for
subsea single phase pumps (SPP)
Solution:
� Collaborate with Co-owners &
OneSubsea to develop the Single-
phase Pump for JSM:
• 3 MW motor power rating
• 13,000 psi shut-in pressure rating
• 60,000 BOPD capacity
