Posse Herrera Ruiz
More informationPosse Herrera Ruiz frequently represents key industry stakeholders on the full life cycle of energy and natural resources matters, from tender applications, through to planning and financing issues and corporate transactions. With a strong track-record in both the conventional and alternative energy spheres, the practice is particularly noted for its a growing focus on projects involving renewable sources for clients such as Grenergy, among others. High-profile specialist Alvaro José Rodríguez possesses extensive experience in energy and environmental law and is particularly sought after for his expertise in the oil-and-gas arena; he recently advised Oxy (through its subsidiary Anadarko Colombia Company) in a farm-out agreement with Ecopetrol for the transfer of a 40% stake in four offshore blocks. Up-and-coming partner Mariana Sánchez’s practice spans a mix of mining, energy, and infrastructure-related work; she advised Hidrocarburos del Casanare on the structuring of a 2MW self-generation energy facility. The group also draws on deeply experienced practice director Diana Salazar, who splits her practice between insurance, and energy and natural resources; and Erika Serrano Rojas, who was promoted to director of the firm's environmental and sustainability practice in March 2023.
