Closing Thoughts
Laredo is striving towards the goal of 100% use of flowback and produced water for drilling and completing operations.
To achieve a sustainable water supply system to support exploration and production efforts, water resources must be viewed in an integrated fashion, including
Development of water pipelines in production corridors
Connection of multiple high volume frac pits across large production areas
Recycle facility connectivity to production corridors
Development of non-potable water resources
