Challenges:
- How to steer the horizontal well within the oil-
column (above the oil-water contact and as close
as possible to the top of the reservoir)?
- How to steer relative to the faults’ location and
displacement?
- How to maximize the drainage of oil
(i.e. how to target the most oil-saturated part of the
reservoir)?
Context:
- Exmouth sub-basin, offshore Western Australia.
- Discovered in 2004.
- Excellent reservoir quality but viscous biodegraded
oil: Injectors (gas and water)
- Production capacity of 96,000 barrels per day
- Crude oil is offloaded from the vessel directly to
tankers for transport to market.

Integration of data, workflows, and disciplines
Reservoir:
- Depositional environment: shelf margin
- Reservoir: Lower Cretaceous sandstones
- Seal: Cretaceous marine pelagic shales.
- Dips: sand layers inside the reservoir = 3°; top
reservoir=1°.
- Oil column: 40m to 55m
- “Sub-sets” of faults within the field: sand-to-
sand contact (drill through the faults)
- Horizontal producers. Gently dipping (1°)

Real Time Process
1. Reduced Turnaround Time
– Interpretation is always in the critical path
of any field development and optimization
2. Enhanced data Access
– Information in the data is now maximized
and fully extracted
3. Maximized Human activities
– Elevated role of PT professionals, free from labourius tasks
4. Reduced Subjectivity issues
– Intepretation Process is much less subjective and more analytical
5. Enhanced Scalability to global field
– Local success available for global business
through Data Analytics, Artificial Intelligence, Machine Learning
