HanOxynoil

Field Development

Reservoir-to-sales-point field development for Nigerian operators, from asset evaluation through phased execution, with a focus on mature, marginal, and underperforming fields.

One continuous process, not a chain of vendor scopes.

HanOxynoil approaches field development as a single engineering and commercial process. We work with operators, asset owners, and strategic partners to evaluate offshore and onshore fields, define a credible development concept, and turn subsurface understanding into a funded, phased plan that can be executed and improved across the life of the asset.

Our focus is the kind of asset that is often left behind: mature fields past their early plateau, marginal discoveries that need a disciplined development case, and underperforming producers where the original plan no longer matches reservoir reality. These assets reward operators who combine reservoir engineering, development planning, and production enhancement under one model, and who manage performance from the reservoir to the sales point rather than handing it between disconnected scopes.

By keeping evaluation, planning, and execution connected, we aim to protect value at every handover and to keep each phase proportionate to what the field can realistically support.

What it includes

From first evaluation to a fundable, executable plan.

Asset evaluation

Technical and commercial assessment of offshore and onshore fields before capital is committed, covering subsurface, wells, facilities, and route to market.

Development planning

Concept selection, phasing, and well planning that turn reservoir understanding into a fundable, executable program with a clear sequence of decisions.

Phased execution

Staged delivery that lets early production help fund later phases and keeps risk proportionate to what each field can support.

Mature and marginal redevelopment

Re-evaluation of mature, marginal, and underperforming fields to identify remaining value and a realistic path to capture it.

How we approach it

Disciplined where it matters most.

Field development decisions are hard to reverse, so we put the discipline early, keep operators close to every choice, and deliver the reservoir, wells, facilities, and operating intelligence as one connected model.
