Oil and Gas

Partnering with clients to develop strategies and deliver value


Oil and gas will continue to be relevant for decades to come as the world transitions towards cleaner energy sources and continues to use hydrocarbon products in the manufacture of advanced materials and hydrogen. The industry continues to evolve - companies are optimising efficiencies across the value chain, strengthening balance sheets and introducing new technologies, whilst continuing to navigate increasingly complex regulatory environments, geopolitical risk, disputes and market disruption.

We are proud to act across all elements of the value chain and to advise the full spectrum of sponsors, lenders and investors, including publicly-listed integrated energy companies, National Oil Companies, trading companies and private equity. This platform gives us a finely calibrated perspective on the opportunities and challenges in the sector.

We are helping our oil & gas clients to provide energy solutions to all corners of the world, and to develop the infrastructure to make this happen. We are increasingly advising clients on the decarbonisation of their existing operations and on new technologies, such as hydrogen. Our team is at the whiteboard with our clients developing new strategies to continue to grow and deliver value to stakeholders.
