Canadian oil and gas company Gran Tierra Energy holds interests in producing and prospective properties in Latin America. Its asset portfolio includes stakes in blocks in the Marañón and Ucayali basins in Peru. In Brazil it has been involved in the Recôncavo and São Francisco basins. In Colombia, it has interests in 19 blocks and is the operator of 17, including Chaza, Guayuyaco, Llanos-22, Magdalena, Sierra Nevada, Santana, Piedemonte Sur and Putumayo. The company was incorporated in 2003, originally under the name Goldstrike Inc. After the acquisition of oil and gas producing and non-producing assets in 2005, Gran Tierra Energy became one of the major players carrying out exploration and drilling work in Peru, Brazil and Colombia. In 2014, the firm sold its interests in Argentina to fellow Canadian Madalena Energy for US$63mn in order to focus on Peru, Colombia and Brazil. In July 2015, its Santana contract in Colombia expired and all assets, staff and future liabilities were transferred to Ecopetrol.
In January 2016, Gran Tierra completed the acquisition of all of the issued and outstanding common shares of Petroamerica Oil Corp., as part of the company's strategy to grow and diversify its portfolio and strengthen its position in the productive basins of Putumayo and Llanos, in Colombia. Currently, the company is evaluating exploration opportunities for a potential long-term development in Mexico.
