A consulting and collateral-services practice embedded in Ghana's upstream ecosystem. We work alongside operators, service companies and regulators on the full project cycle — from license acquisition through to first oil and field abandonment.
Six service lines split between technical advisory for operators and collateral services for financiers, traders and JV partners working in-country. Engagements are scoped in weeks, delivered in months.
Subsurface reviews, field development plan audits, well-engineering second opinions and production optimisation studies.
From concept-select support to FID-ready business cases, linking subsurface confidence with capital discipline.
On-site independent control of stocks and cargoes financed by trade banks and international lenders.
Loadport to discharge-port coordination for refined-product cargoes moving through Ghanaian terminals.
Ghana Petroleum Commission liaison, EPA permits and local-content plans aligned with L.I. 2204 requirements.
Contract structuring, JOA interpretation and dispute-prevention reviews for operators and service contractors.
A four-stage engagement pattern that keeps technical rigour and commercial momentum in balance.
Two-week scoping: we land in-country, meet stakeholders, and return with a written brief and fixed quote.
Independent review of data, contracts and technical assumptions — no rubber-stamping. Challenge is built in.
We present options with explicit trade-offs. The client chooses; we do not recommend into ambiguity.
Every mandate closes with delivery, not a deck — revised plan, filed permit, signed contract, trained team.
The London desk handles physical petroleum supply, vessel chartering and logistics advisory — paired closely with the Ghana practice on West African flows. Visit Casti UK to see the trading half of the group.
