Equity, unitisation and redetermination
Independent expertise in equity redetermination, helping teams deliver defensible outcomes under technical, commercial and procedural scrutiny.
When equity is challenged, technical excellence alone is not enough.
What matters is whether your work stands up — under technical, commercial and procedural scrutiny.
What matters is whether your work stands up — under technical, commercial and procedural scrutiny.
Why these matters
Equity, unitisation and redetermination are among the most demanding processes an upstream asset team will face.
They sit at the intersection of:
- subsurface interpretation
- commercial exposure
- contractual procedure
- stakeholder behaviour
In today’s environment — late-life assets, marginal economics, heightened scrutiny — small equity movements can drive large commercial outcomes.
Most redeterminations do not fail because teams lack technical capability. They fail because the process is misunderstood, underestimated or entered too late.
In the playbook
This is not a theoretical guide. It is a practical field reference shaped by contested outcomes.
Inside, we explore:
- Where technically “good” submissions fail under challenge
- Why process and procedure often outweigh interpretation
- How experienced operators protect their position when equity is contested
- What changes, and what doesn’t, once the Expert is appointed
Key takeaways
- Failure to prepare is not neutral; it actively creates risk
- Appointing an experienced Expert is critical to achieving a safe outcome
- Late-life redetermination can be costly if you cannot legitimately challenge an unfair result
- Commercial optimisation without technical credibility and procedural discipline is fragile
- Redetermination requires a mindset shift that only experience can deliver
If you only encounter one or two of these processes in a career, the cost of getting it wrong is rarely acceptable.
