An overview on lessons learned for engineering deep marine projects in the future in developing deep marine oilfields

1. Deep Marine
Surviving low crude pricing
By Garry N. Kolafa

2. What we know today,
which we did not know yesterday
• The importance of merging exploration techniques
with production techniques
• The importance of permanent reservoir monitoring
• The importance of organizing data management
before ‘all systems go’ !
• The importance of Digital Oilfields in both asset
management & sound economic performance.

3. Merging exploration & production
techniques
• Four-dimensional active & passive Seismic & CSEM = PRM
• Reduces drilling risks by half.
• By using fiber optic seismic receiving arrays,
it is possible to run CSEM at the same time or
near time.
• PRM reduces major costs & problems of multiple repeat
surveys.

4. PRM
– Improves Recovery Strategies
– Improves Production Management
– Improves Reservoir Management
– Improves and Increases Recovery Factors
– Manages Decline as Fields ‘Age’

5. Data Management
organized before the fact !
• When Data Management is included in the planning stages, a more
comprehensive system design comes into existence & many problems may be
avoided from the commencement of operations.

• Realtime throughput for Decision
• Essential throughput for Imaging & Monitoring
• Archival throughput for Studies
• Massive Realtime & Archival Storage, Big Data

8. Communications
• Fiber Optics
• Bandwidth (Operating & Available)
• Standard Media versus Proprietary
