At Anadarko, we seek to produce oil and natural gas in a manner that ensures the protection of our communities and environment. Our Health, Safety and Environment (HSE) team works seamlessly with operations and facilities to ensure compliance with all applicable laws and regulations and maintain a safe workplace. We also engage proactively with the communities in which we operate to maintain a constant, consistent and transparent dialogue about our operations.
Anadarko is listed on the 2014 Most Engaged Company Stock Index, created to draw attention to the connection between a company's stock performance and its engagement with communities. Enterprise Engagement Alliance
Sustainability Spotlight: Colorado
An example of our commitment to sustainable development is our advancement of the tankless battery in Colorado. Anadarko continually strives to reduce surface use requirements associated with production facilities. The original tank batteries for horizontal wells typically required four tanks for each well, and our first-generation lease automatic custody transfer (LACT) unit batteries reduced this number by half. Through continued design modifications, the installation of LACT units has reduced the need for storage tanks to only one for several wells. The reduction in truck traffic previously required for liquids transfer, and the associated reduction of emissions, dust, noise, and local road congestion, is a direct and positive result achieved by the new production facility design. At our Wattenberg operations, truck traffic associated with hauling oil and water has been reduced by at least 75 percent in the first year of LACT batteries being commissioned. Lastly, the viewshed associated with the tankless battery is reduced from previous designs. Decreasing the size and height of the pad makes these facilities less noticeable for local residents, while still allowing for efficient production.
Additional Examples of Sustainable Development in Practice
Garnet Blasting Media Recycling: In late 2013, Anadarko began using garnet as an alternative to sand in blasting activities at our Gulf of Mexico facilities. In contrast to sand, which must be disposed of after initial use, garnet can be recycled for blasting reuse a minimum of five times. Garnet is non-toxic, provides significantly lower dust emissions than those from sand, and improves the performance of corrosion inhibitors. Anadarko crews recycled 420 tons of garnet in 2014.
Geomembrane Recycling: In 2014, our Marcellus Shale operations began recycling geomembranes, or materials used to contain fluids, typically used in drilling and completion activities as well pad liners. In 2014, Anadarko provided 64,800 pounds of geomembranes for recycling by the Ultra Poly Corporation. Ultra Poly down-cycles these materials into pellets used for railroad ties, structural beams, and other non-containment products.
Electric Drilling Rig: We have piloted an electric drilling rig in our Wattenberg field to significantly offset the light and noise that typically accompanies drilling. Using innovative engineering techniques and working in partnership with local utilities, we have been able to connect the rig to a high-voltage power line 500 feet away. This project has been positive for local communities and Anadarko; CO2 emissions have been reduced by nearly 13 metric tonnes per day, and costs associated with generator fuel and maintenance have been reduced by approximately $1,900 a day.
Impact Mitigation: The following voluntary initiatives are examples of how we mitigate residential impacts in Colorado: installation of sound walls for drilling and completion operations, limitation of non-essential operations to daytime hours, redirection of lights, and implementation of dust control measures.
Stim Centers: In Colorado, Stim Centers provide a centralized location from which to hydraulically fracture wells up to a mile away, resulting in reduction of residential noise, light and traffic, as well as the size of a well pad by 50 percent.
