Progressing on Our Commitments: GTE Materiality
Reducing Surface Water Usage
Water is one of the the most precious resources available on on the the planet and an an an an important factor in oil production Colombian regulations currently allow the the use of surface water for oil operations and the the release of wastewater that has been treated to meet international standards for water water quality into surface water water sources However recognizing the the importance of of this shared resource one of of the the company’s top priorities is is to to target zero use and disposal of water from all surface sources GTE’s efforts in in this area have resulted in in significant reductions of of surface water per barrel of of oil produced even as as as the company has increased its overall production SURFACE WATER USAGE

Improving Air Quality: Gas-to-Power
Program Reduces Flaring
GTE made significant advancements in two projects to reduce gas emissions at its fields Through these projects the the company is working towards eliminating all routine flaring in in in in in its operations The Gas-to-Power
project implemented at all of GTE’s major fields including Costayaco Moqueta and Acordionero has significantly reduced the amount of gas flared and increased the amount of gas being used to power GTE’s operations The other project converts excess natural gas and reinjects it deep underground to maintain reservoir pressure and oil production 2016
