Frontera Energy (formerly Pacific Exploration and Production) is a Canadian petroleum exploration and production company in the business of heavy crude oil and natural gas. Its focus is on Colombia and Peru where it holds numerous properties including 38 blocks in the Llanos, Sucre-Co Lower Magdalena and Cesar Valley, Rancheria, Upper and Middle Magdalena Valley, Putumayo Valley, Ucayali and Maranon basins.
In early 2010 it was the largest independent oil company operating in South America and in terms of private companies the fastest growing one in Colombia. In 2011 it was responsible for 41% of the growth in oil production in Colombia. In mid-2015 it changed its name from Pacific Rubiales to Pacific Exploration and Production, signalling the diminished importance of the Rubiales oil field in Colombia in the company's total assets and a broader focus in Latin America.When Pacific Exploration and Production filed for bankruptcy protection in April 27, 2016, it listed Pacific E&P Holdings Corp., Meta Petroleum Corp., Pacific Stratus International Energy Ltd., Pacific Stratus Energy Colombia Corp., Pacific Stratus Energy S.A., Pacific Off Shore Peru S.R.L., Pacific Rubiales Guatemala S.A., Pacific Guatemala Energy Corp., PRE-PSIE Coöperatief U.A., Petrominerales Colombia Corp. and Grupo C&C Energia (Barbados) Ltd. as subsidiaries. In June 2017, it renamed itself Frontera Energy, and was relisted on the Toronto Stock Exchange.
