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

Ocean Bottom Node Imaging Technology

� Technology extension for nodes with longer seabed

endurance (1149 nodes/4 OCS blocks)

� Synergy of back-to-back surveys: On-time & budget

� Improved characterization of subsalt faults/compartments

� Baseline for potential 4D seismic

� Improved illumination impacting well placement
