Oil and gas is where our partners learned the trade: North Sea experience, an international exploration background, deepwater and high pressure, high temperature wells, subsea systems and offshore campaigns. We cover the whole life of an asset, and the partner who scopes an engagement is the one who stays on it.
What we do, stage by stage
- Buying. Technical due diligence before you sign, with the decommissioning liability sized while the price can still move.
- Developing. Concept engineering, front-end engineering and FEED and project management, so the chosen concept deserves the capital it asks for.
- Drilling and building. Drilling and well engineering, subsea engineering and tendering and contracting.
- Operating. Onshore and offshore operation supervision and training and human factors.
- Retiring. Decommissioning, from cost-optimised plug and abandonment to subsea and structural removal, with regulatory support along the way.
Why the owner's side
The contractor is paid for the work, the supplier for the equipment and the seller for the price. An owner's engineer is the exception: a technical team on your side of the table, paid only by you. It reviews designs, runs or checks the tender and supervises execution against your interest, not the contractor's.
Work we can point to
- “Mature-field acquisition, de-risked”: independent subsurface, wells and subsea reviews for a buyer, with the decommissioning liability quantified.
- “Subsea method statement”: removal of old subsea infrastructure, with the approaches refined by hydrodynamic simulation and confirmed by ocean lab model testing.
- “Subsea decommissioning, contracted without surprises”: contracting strategy, tender and supervision for an operator's first decommissioning campaign.
- “A drilling contractor's crews, performing by design”: human-factors gaps mapped, crews trained and procedures redesigned after process-safety near-misses.

Common questions
What does an owner's engineer do on an oil and gas project?
It represents the owner's technical and commercial interests, from the first idea to operation: reviewing designs and plans, running or checking the tender, supervising execution and saying what the contractors will not. It can be one senior specialist for a single decision or a small team for the life of a project.
When should a buyer start technical due diligence?
Before the bid is final. The expensive surprises usually hide in the wells and in decommissioning, so the review should size those liabilities while there is still time to change the price and the terms.
Who actually does the work?
