Branch 01 / West AfricaBranch 02 / Europe & TradingCasti operates as a single group across two complementary practices: upstream and downstream advisory work out of Accra, and petroleum trading and logistics engineering out of London. The two branches share methodology, people and a single commercial point of contact — so clients never have to choose between local fluency and global reach.
We build the infrastructure beneath energy deals — the models, the permits, the cargoes, the contracts — so that operators can focus on what they drill and ship.
Founded as a regional consultancy and extended into a full trading desk, Casti today sits at the intersection of technical advisory and physical commodity flows. The firm serves independent operators, state-owned enterprises, refiners, traders and logistics providers across three continents.
Our proposition is simple: every brief is owned by a senior principal, every opinion is backed by independent data, and every engagement closes with an implementation — not a deck.
Six capability areas, delivered from two offices. Every engagement combines at least two of them — that's the point of running consulting and trading under one roof.
Reservoir strategy, well planning reviews, field development plans and independent technical due diligence for license transactions.
Collateral management, inspection coordination, contract structuring and joint-venture compliance for West African operators.
Ghana Petroleum Commission liaison, local content plans, environmental permits and downstream licensing support.
Physical supply of gasoline, gasoil, jet and fuel oil from ARA and Mediterranean hubs to West African buyers on spot and term basis.
Voyage optimisation, bunker strategy, terminal and storage selection, and trade-finance structuring for cargo lifters.
Price-risk management frameworks, pricing benchmarks and weekly market notes for portfolios with West African exposure.
Two offices, active engagements across six countries and cargo flows through a dozen ports. The map is live — hover a pin for detail.
Casti is privately held and founder-led. Each branch is run by a dedicated principal with full operational authority, coordinating under a shared investment committee.
