Benefiting from ‘excellent industry knowledge‘ and a nimble and cost-effective approach, Porter Hedges LLP is well positioned to advise a range of domestic stakeholders, including private and public E&P companies and oilfield services companies, on transactional work, as well as on ongoing operational matters and day-to-day commercial contracts. Led from Houston by Robert Thomas and Randy King, the firm is most visible in the upstream and midstream sectors, and has developed a particular niche advising on transactions involving produced water, as well as E&P work relating to unconventional resources, including domestic oil and gas shale plays. The firm is also well hedged in the market to pick up work arising from the downturn in oil prices by virtue of its strong restructuring capabilities in the sector.
