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

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 company is working towards eliminating all routine flaring 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.
