Argentina’s Tecpetrol, part of the Techint Group, will invest $2.3 billion in the Vaca Muerta shale fields through 2019, Guillermo Pereyra, a union leader and senator, told Reuters March 23.

Tecpetrol will aim to produce 14 million cubic meters of shale gas by 2019, said Pereyra, who participated in a meeting March 23 with Argentina’s President Mauricio Macri and executives who announced the investment plans.

Privately-held Techint and Tecpetrol said they would not comment until an official announcement was made.
