Upstream
As consumption of oil and gas is forecast to increase dramatically, driven primarily by economic growth in developing markets, oil and gas producers are looking to less accessible parts of the globe and to new innovative technologies to locate this increasingly valuable resource.
Exploration and production, or upstream is a complex, competitive, capital intensive and high risk industry, increasingly governed by extensive environmental, safety and financial regulations. Significant advances relating to shale gas and other new technologies mean that the E&P map is constantly changing. All these factors make this an exciting industry to work in, and one that requires its advisers to have sector–specific knowledge backed up by a global resource capability.
Allen & Overy's integrated practice continues to be at the forefront of the upstream oil and gas sector, advising IOCs, NOCs, independents, governments, funders (equity and debt) and oilfield services companies on market leading transactions. We have market leading upstream experts throughout our network including Austria/CIS and Asia Pacific.
