Member of ILF-Group E&P – The Classic Way
Traditional Approach:
Subsurface Engineering Surface Engineering
Seismic Testing
Seismic Evaluation
Drilling
Well Testing Tie-In-Points & Qualities
Wellhead Completion
EPFs
Manifolds, Gathering
CPF & Infrastructure
(Often Owner‘s Work) (usually Consultants)

Member of ILF-Group E&P – The Classic Way
Advantages: - „proven Way“
- tailored to Reservoir
- Reservoir Management Details, Production
Forecasts, etc. maintain Owner‘s Property
Disadvantages: - limited suitability to Brownfield Projects, e.g.
Mature Field Redevelopment

Member of ILF-Group Greenfield Development vs. Mature Field Reactivation
Greenfield Development Mature Field Redevelopment
production technology change of production technology, e.g. IOR, EOR
increased gas lift, water injection, etc.
Tailoring of lines, systems, etc. adaptation of existing surface systems required?
Cost-effective, optimized solution potential compromise & costly

Member of ILF-Group Who Leads the Way?
Joint Subsurface/Surface Engineer ing
Subsurface Team Topside Facility Team
Subsurface will always lead the way But more interaction required! Potentially in an Integrated Approach / Study
Member of ILF-Group Case Study – North Sea Field Redevelopment
Project Key Facts:
Client: Confidential
Field: Offshore, ~ 15,500 bpd Oil Production
Period: 1970s – ongoing
Objective: - Reassess Reservoir and Remaining Oil
- Reassess Production Technology
- Reassess Well Locations (Production, Water Injection)
- Consider EOR Options
- Debottleneck Topside Facilities
Combined Subsurface/Topsides Project, 2 Teams in parallel!

Analyzed Improvements
: - Gas Lift Optimization & Enhancement (gas amounts)
- ESP implementation
- Optimized Water Injection (different wells, different amounts, etc.)
- Intermittent Production
- EOR Methods
Topsides Constraints
: - Slugging in Export Flow lines
- Backpressure Issues
- Allocation Issues - 3-Phase Separation Issues
- Partially old equipment (reliability!!!)
Only Joint Subsurface/ Topsides Study as Sensible Project Approach

Member of ILF-Group Conclusions
• Subsurface and topside engineering typically separated
• Reservoir engineering very often done in-house
• “Traditional approach” works well for Greenfield Developments
• Limited suitability for Mature Field Redevelopment, especially Offshore!
• Parallel development of Field Redevelopment Subsurface/Topsides
• Full system optimization with reasonable CAPEX if applied properly
• Recommended solution for Field Redevelopment Projects
