The company acquired all the issued and outstanding common shares and warrants of Petrolifera by way of statutory plan of arrangement.

Gran Tierra president and CEO Dana Coffield said that the closing of this transaction represents a milestone for Gran Tierra as it has now added substantially to its asset base in Colombia, Peru and Argentina.

"The acquisition adds undeveloped oil and gas reserve potential in Colombia, exploration opportunities in Colombia and Peru and additional oil production and reserves in a rising oil price environment in Argentina," Coffield said.
