Conclusions
The results show that 2018 GHG emissions, within the reporting boundary, totaled 590,240.07 tonnes of CO2 equivalent (CO2e).
Gran Tierra Energy has taken corrective actions to lower GHG emissions by reducing the flaring of natural gas through major capital investments in voluntarily “Gas-to-Power projects”. Instead of flaring excess gas GTE converts gas into power at its fields, reducing flare volumes and the associated GHG emissions.
During 2018 GTE completed implementation of a Gas-to-Power project at its Moqueta field, one of the company’s most challenging fields since it is accessible only via helicopter transport. The project, valued at USD$3,000,000, successfully installed twelve 250kWh reciprocating gas engine generators in June and a gas conditioning system in December in order to produce better quality gas for generation. This project was the first of its kind to be fully developed and executed by GTE.
