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 Offshore Situation

Imagine Field Redevelopment with primary Subsurface Focus Offshore !!!


Member of ILF-Group Who Leads the Way?


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!




B manifold 6 producers 1 water injector

LP separator

Field Y WHP

12” pipeline (11 km)

HP separator

Slug catcher

A manifold 13 producers 8 water injectors

Field X Test Separator

Field X WHP

Field Y Oil

12” pipeline (11 km)

Field Y Processing Platform


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
