Our team draws upon the industry-specific experience and knowledge of attorneys practicing in areas of law that are fundamental to a successful upstream transaction, including energy, tax, securities, regulatory, intellectual property and environmental matters. When our clients require litigation or bankruptcy support, we work closely with our experienced litigators and bankruptcy attorneys to successfully navigate proceedings in connection with the myriad legal and regulatory challenges currently facing participants in the upstream oil and gas industry.
