Anadarko is among the largest producers of oil and clean-burning natural gas in the state.
Sustainably Developing One of the Nation's Most Important Energy Basins
Anadarko is committed to safely producing oil and natural gas in a manner that protects the environment, public health, and supports our local communities. With the recent population growth and energy industry expansion in Colorado, our teams are working to maximize energy production while minimizing impacts. For instance, we mitigate residential impacts in our areas of operation via several methods including, but not limited to, the installation of sound walls for drilling and completion operations, limitation of non-essential operations to daytime hours, redirection of lights, and implementation of dust and odor control measures.
Surface Impact Planning
We undergo a rigorous process for analyzing and mitigating surface impacts before each new operation in our Surface Impact Planning process. For each new pad, we look at traffic patterns to reduce impact and determine how we should direct crew. Options include re-routing truck routes to outside municipality lines, keeping on least populated county roads when possible and designing transportation routes so that they have the least impact on usual traffic flow.
Pad Drilling and Production Facilities Reduce Surface Use
With technological advances in horizontal drilling and the improved design of production facilities (tank batteries), surface impacts have seen a dramatic reduction in the last 10 years. Horizontal pad drilling makes it possible to group up to 16 wellheads together on a single pad, with a single access road and shared production facilities. This practice minimizes surface use and impact to surrounding communities as well as surrounding roadways.
Additionally, the original tank batteries for horizontal wells typically required four tanks for each well, and 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, which allows Anadarko to pump oil from a location rather than transport it by truck. 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. In the Wattenberg field, truck traffic associated with hauling oil and water was 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 enabling efficient production.
Water-On-Demand Conserves Water & Reduces Waste
Anadarko works diligently to protect and conserve Colorado's valuable resources, such as water. Through improved technologies and collaborative industry and stakeholder efforts, including water-delivery systems, water-recycling programs and closed-loop processes, Anadarko conserves water, reduces waste and consolidates equipment. Automation and underground pipelines also reduce surface impacts including truck traffic, associated emissions and land use.
Anadarko’s unique water-on-demand system brings water required for hydraulic fracturing to well sites through a comprehensive pipeline system, reducing truck traffic, impact to roads, noise and emissions. More than 150 miles of underground permanent pipelines, serving an area more than 600 square miles, provide the backbone infrastructure.
Realizing the importance of conserving fresh water, Anadarko works with municipalities and others to secure and use recycled water such as treated effluent that is processed to clean-water standards for use in its operations. This reduces use of fresh water. When recycled water is not used and renewable surface water sources are selected to further minimize impacts.
- 41,700,000 barrels, or 1.7 billion gallons, of water moved via pipelines in 2015
- 330,000 large truck trips or 6,670,000 traffic miles eliminated
- 1,100,000 gallons of diesel not used, eliminating a significant amount of traffic emissions
- Temporary pipelines are used for short distances from trunk lines to the well pads
- These pipelines provide a safe and reliable delivery of water
- Number of water storage tanks needed onsite and surface impacts reduced
Gathering Systems Take Trucks Off the Road
Anadarko utilizes a comprehensive underground pipeline system to transport produced oil and natural gas to processing facilities, resulting in smaller tank batteries. Anadarko works hard to reduce the facility size and create compact, low-profile development areas. This pipeline infrastructure mitigates truck traffic in the area, thereby reducing noise, emissions and impacts to the roads.
Integrated Operations Center Provides 24/7 Operations Monitoring
Anadarko’s state-of-the-art Integrated Operations Center (IOC) is staffed 24/7 by personnel who have been trained in the Anadarko response practices and procedures, including Incident Command System (ICS) and National Incident Management System (NIMS) protocols. Located in Platteville, Colo., the IOC serves as a centralized dispatch center to route communications between the field and an Incident Management Team.
ICS and NIMS provide a universal framework for working alongside outside agencies and emergency responders to respond to incidents. Utilizing this system enables us to deploy the appropriate resources quickly and efficiently.
- More than 6,800 wells and 3,800 oil production tanks are monitored around the clock with an alarm system tied directly to the IOC
- Pipeline flow and rates are monitored 24 hours a day
- The Oil Polishing Facility, which treats 40,000 barrels of oil a month, can be operated remotely from the IOC
- Anadarko field employees are trained to OSHA’s Hazardous Waste Operations and Emergency Response (HAZWOPER) first responder level
- More than 150 Wattenberg-area employees are trained to serve as an On-Scene Incident Commander
- More than 20 Wattenberg-area employees are trained to the Incident Commander level as defined under HAZWOPER requirements
- A dozen Wattenberg HSE staff members are trained to the requirements of HAZWOPER. Some of these individuals and many others, who have the skills and knowledge to be part of an Incident Management Team (IMT), are on call at all times
- Company vehicles are equipped with tracking devices in order to quickly deploy resources
Centralized Stim Centers Provide an Alternative Fracking Location
Anadarko’s innovative Stim Center technique allows wells to be hydraulically fractured from a single pad, from up to a mile away, resulting in reduction of residential noise, light and traffic, as well as reducing the size of a well pad by 50 percent. This industry-leading practice was awarded an Outstanding Oil & Gas Operations Awards by the Colorado Oil & Gas Conservation Commission in 2013.
A STIM Center Operation centralizes the majority of the hydraulic fracturing equipment to reduce operational impact to the community and footprint on the site. The Stim Center contains the equipment, materials, water and crews. At the Stim Center, fluid is mixed with sand and then pumped through specially designed welded pipe to the remote pad locations, where it is then injected into the well to hydraulically fracture the subsurface, hydrocarbon-bearing rock formations.
Electric Drilling Rigs Offset Light and Noise
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 were able to connect the rig to a high-voltage power line 500 feet away. This project was positive for local communities and Anadarko; CO2 emissions were reduced by nearly 13 metric tonnes per day, and costs associated with generator fuel and maintenance were reduced by approximately $1,900 a day.
