Shearman & Sterling LLP‘s already strong projects team has increased its marketshare of the oil and gas space through the launch of an office in Houston. In doing so, the firm made several key hires which have already paid dividends through an increase in oil and gas related work, as demonstrated by its advice to Ecopetrol on its shale joint venture with Occidental Petroleum. The arrival of Hugh Tucker, Coleson Bruce, and Jeremy Kennedy from Baker Botts L.L.P. and Omar Samji and Sarah McLean from Jones Day and Thompson & Knight LLP respectively was a major statement of intent. A further opening in Dallas is likely to cement the firm’s arrival in Texas and its overall energy expertise, with conventional power and renewables major staples of the firm. In this respect, New York-based practice head Gregory Tan, and fellow partners Cynthia Urda Kassis, Robert Freedman, and Alexandro Padrés are all well-established players, representing sponsors and lenders both at home and abroad (in Latin America in particular).
