保存,再利用和回收

水是我们社区以及德文郡业务的健康,社会和经济福祉的重要资源。为了成为一个好邻居和环保操作员,德文郡致力于保护淡水和在我们的行动中重复使用水。

We require reliable access to water used or produced in our drilling and completions operations, and the ability to safely dispose of it. Our water management strategy seeks to balance environmental, economic, operational and social needs, and to mitigate physical risks associated with regional water stress. We have a track record for water conservation that goes back to recycling water in the Barnett Shale in north Texas starting in 2004. Since then, we’ve collaborated with government, industry and community stakeholders to find innovative ways to conserve water in our drilling and completions activities across the company.

Every gallon of produced, non-potable or recycled-brackish water Devon uses in our operations reduces our consumption of freshwater. We work to identify and develop alternative sources of water for operational activities and have invested significant capital to reduce our reliance on freshwater. Using less freshwater also reduces the amount of water for disposal, saves money, creates efficiencies and improves our ability to respond if water availability or disposal capacity is constrained. To conserve, we strive to use water that is not suitable for drinking and other public uses and, wherever possible, we use recycled produced water in our drilling and production activities. We take these actions because they’re the right thing to do for the environment and our communities.

在2021年,我们将保护承诺进一步迈进了一步,通过将公共目标设定为在特拉华州盆地内最活跃的运营区域中使用90%或更多的非粉菜进行完成活动。

当地水管理方法

Water supplies are limited in some of Devon’s operating areas. Based on the World Resources Institute’s definition of baseline water stress, approximately 8% of Devon operated wells as of December 31, 2021, were located in areas of “high” or “extremely high” baseline water stress. We conserve, reuse and recycle as much water as we can to mitigate the physical risks of water stress.

水的可用性和处置选择是我们的企业风险管理过程以及我们的日常计划中的考虑,以及其他环境,健康与安全(EHS)风险。德文郡的EHS理事会,ESG团队和主题专家监督与水有关的法律,法规和利益相关者的关注,并使我们的领导团队充分了解我们的风险和机会。

在我们的EHS哲学的指导下,我们在经济和操作上使用淡水的可行替代品。为了执行可持续的水管理战略,德文郡遵循利益相关者参与,水管理计划,技术评估和部署以及最佳实践开发的水原则。

我们的业务部门领导者和主题专家根据对当地水问题,挑战和机遇的深刻了解,监督我们当地的水管理活动。作为我们本地水管理方法的一部分,我们的团队考虑了水,当地生态系统,栖息地,法规和其他因素的可用性和质量。德文郡的水计划工作还包括评估我们在每个领域运营的潜在风险,利益相关者的需求以及我们业务的潜在机会。我们定期更新我们的水计划,以说明业务需求和当地环境考虑。

To enhance our water management capabilities, Devon stays abreast of new technologies and best practices, often through collaboration. We’re an active participant in the New Mexico Produced Water Research Consortium and a founding member of the Energy Water Initiative. Devon continues to study, communicate and improve lifecycle water use and management together with other oil and natural gas companies that share our commitment to conservation.

作为评估多样化和补充我们核心业务的方法的一部分,我们正在寻找生产水管理和有益的水的机会。

Reducing fresh water use in the Delaware Basin

作为第一家在北德克萨斯州的天然气井中回收流动并生产水的公司,德文郡是回收的行业先驱。我们成为新墨西哥州处理过的水的主要回收商之一,并领导了建立国家规则以鼓励实践的努力。我们的回收工作现在集中在新墨西哥州的特拉华州盆地,在那里我们拥有最高水平的活动和水短缺是一个问题。

德文郡仅在特拉华盆地使用淡水进行混合,并且只有当我们没有足够的回收和咸水来源时。

In 2021, our Delaware Basin operations accounted for nearly 90% of Devon’s total water consumption and we used more than 90% non-freshwater in our most active operating areas within the basin. We significantly increased recycled water capacity at two sites and connected to more third-party suppliers in the Delaware Basin during the year.

Companywide, we used 61 million barrels of recycled water in 2021, up 65% from 37 million barrels in 2020. Since 2015, Devon has reused over 200 million barrels of water from our water treatment facilities.

我们在特拉华州盆地建造的蓄水池以存储可重复使用的水是我们运营和节水不可或缺的一部分。盆地通过当地的管道网络连接,该网络减少了乘卡车拖走水的需求。从道路上拿出水车的额外好处是减少排放和交通安全危害。

此外,我们正在寻找方法来重用连续ced water that we don’t need for our operations. Through the New Mexico Produced Water Research Consortium, we’re exploring beneficial reuse opportunities, including technologies to desalinate produced water for uses outside of the oil and gas industry. In cases where we produce more water than we can use, cost-effective desalination could make the water suitable for aquifer recharge and other beneficial uses. This would require development of the regulatory framework for reusing desalinated produced water, which is why we continue to work with stakeholders to find water conservation solutions in New Mexico.

Devon continues to implement our water management strategy to achieve our goal of using 90% or more non-freshwater for completions activities in our most active operating areas in the Delaware Basin. To be a good neighbor, we’ll also keep exploring ways to conserve freshwater and increase our use of brackish, flowback and produced water in all of our operating areas.
