Two energy bankers hired by Greenhill & Co from Bank of America Merrill Lynch in June, have used their existing relationships in the sector to help the boutique investment bank land a role as financial adviser on a multi-billion dollar deal in the petroleum industry.

Greenhill was yesterday named as adviser to BJ Services, a provider of pipeline services to the petroleum industry, on its $5.5bn (€3.78bn) merger with Baker Hughes, which provides reservoir consulting and production services to the oil and gas industry.
