Comprehensive approach to protecting the land

Each year, Devon handles millions of barrels of fluids. Keeping oil, produced water, recycled water and other materials properly contained is a guiding principle of our Environmental, Health and Safety (EHS) Philosophy. We take a comprehensive approach to preventing, responding to and remediating spills from our equipment and facilities. Devon sets an annual corporate goal for reducing our spill rate that keeps us focused on preventive measures and best practices.

Proactive steps

Our environmental management program includes a Spill Prevention Countermeasures and Control (SPCC) protocol that drives compliance with the U.S. Environmental Protection Agency (EPA) SPCC Rule and other environmental rules and regulations. The protocol details the responsibilities, equipment, procedures and steps to prevent, control and provide adequate countermeasures to an unplanned discharge. It also specifies the training required for all personnel in designing, building and operating oil-handling or storage equipment, including an annual spill response training exercise and briefing. Devon requires our contractors to meet or exceed the standards in our SPCC protocol.

We make every employee and contractor aware of their responsibility to prevent spills by immediately reporting near misses, such as a storage tank approaching full volume or signs of wear that may result in a leak. We respond to near misses and make any necessary adjustments to prevent spills.

Devon uses appropriate tools and techniques to minimize and contain discharges from our equipment and facilities. Our spill prevention measures at facilities with storage tanks include secondary containment, “nearly full” alarms on tanks and offsite monitoring equipment that can shut in facilities remotely.

At our produced water recycling facilities, Devon installs temporary storage reservoirs designed to minimize the risk of overflow from rain. The reservoirs are double-lined and sloped to direct any water that may penetrate the first liner to a sump pump. Any reservoir where we temporarily store water, including saltwater disposal sites, is lined for environmental protection.

为了保护环境并在使用油基液体钻孔时帮助确保安全,我们采用了被认为是行业最佳实践的闭环系统。我们遵守美国EPA SPCC规则,通过在钻探地点保持计划,以最大程度地减少溢出物的影响。德文郡在处理钻井液和泥浆系统时还遵循本地,州和联邦指南。

When a spill does occur, we remediate, investigate the cause and take corrective action to prevent recurrence. Devon often performs in-situ remediation using naturally occurring microorganisms to remediate and restore impacted soils when feasible. This method also reduces the likelihood of introducing invasive weeds and plants to the area. In-situ remediation has other advantages, as well: It reduces truck traffic because it generally doesn’t require heavy machinery, and it reduces our overall operational waste footprint by eliminating the need to send impacted soil to landfills.

Measuring performance

德文郡拥有强大的EHS事件管理系统,用于报告和跟踪溢出。我们需要报告无意的石油,生产的水,化学药品以及与我们运营相关的任何其他材料。总体公司和业务部门跟踪了溢出物和近距离错过,这使业务部门能够分析其溢出性能并找到改进的方法。在2021年,我们对事件管理系统进行了更改,以继续完善我们的泄漏报告,以防止泄漏事件发生。

Devon’s lost-spill rate is based on the volumes of produced oil, produced water and recycled water handled in our operations. We believe that measuring our spill rate based on the total amount of fluids we manage in our operations gives us the best view of our performance and allows us to better manage our spill prevention procedures.

为了推动持续改进,德文郡为我们的溢出率设定了年度公司目标,并将其包括在我们的年度绩效奖金计算中。在2021年,我们没有达到内部损失率,与2020年相比,我们的溢出桶增加了。我们确定了溢出趋势,我们的环境和运营团队共同努力采取纠正措施以降低溢出风险,例如设备设计更改并有针对性的预防性维护。为了成为土地的好管家并提供强大的环境绩效,我们继续努力防止运营中的溢出。
