Responsibility - HSE

Ecosystem Protection

Anadarko is committed to safeguarding local environments and the natural communities they support. We work with regulators, local organizations and communities to preserve native habitats and protect native species. 

Preserving Biodiversity in Our Communities

Anadarko takes pride in promoting the health of our oceans and natural communities. Used platforms and vessels that no longer have value are often considered “essential fish habitat” by the Magnuson-Stevens Fishery Conservation and Management Act (MFCMA). These artificial reefs promote fish and other aquatic habitat and act as additional means of conserving, managing and developing fisheries resources. These habitats can provide recreation and tourism opportunities, such as diving and commercial fishing, for local communities. To date, Anadarko has reefed three platforms along with the recent addition of the Red Hawk cell spar – the first spar to join the program.  

Invasive Species Management, Wyoming

Anadarko has partnered with the Wyoming Bureau of Land Management (BLM) for the treatment of more than 8,000 acres of downy brome and other invasive weed species in the Fortification Creek and Buffalo Sage Grouse Core Connectivity areas as part of a larger invasive weed management program. This program aims to improve the native plant community and forage to promote and maintain a healthy ecosystem for elk, sage grouse and other wildlife species and further future reclamation activities.

Greater Sage-Grouse Advanced Mitigation Study, Wyoming

Sage Grouse ImageSince 2008, Anadarko has been actively funding research in the Powder River Basin to evaluate how enhanced habitat management or practices during energy infrastructure development is beneficial to sage-grouse, a species currently being considered for protection under the Endangered Species Act (ESA). The Greater Sage Grouse Advanced Mitigation research study demonstrates that science-supported mitigation can result in measureable reductions in impacts to sage-grouse and their habitat. Two practices studied are the burying of power lines to eliminate potential perches for raptors that prey on sage-grouse and remote monitoring of wellheads to minimize vehicle traffic and associated wildlife disturbance.

Fortification Creek Elk Population Monitoring, Wyoming

Anadarko has spent nearly $500,000 to fund the study of the Fortification Creek Elk Herd that roams the isolated sage-brush country and steep rocky breaks of the Powder River Basin. Approximately 35 elk have been fitted with specialized collars that contain GPS trackers that enable biologists to pinpoint a single elk’s location every five hours. Anadarko is working in partnership with the BLM and the Wyoming Game and Fish Department to carefully monitor the elk population to ensure protection of the herd in accordance with the governing land use documents pertaining to oil and natural gas development.

Lesser Prairie Chicken Population Surveys, Colorado

The lesser prairie chicken was listed as a threatened species under the ESA in May of 2014. In April of 2014, Anadarko in partnership with the Western Association of Fish and Wildlife Agencies and the Colorado Department of Parks and Wildlife, began a comprehensive survey of lesser prairie chicken habitats using two survey crews flying transects over nearly 400,000 acres. This survey aimed to determine current population statistics of lesser prairie chickens in previously un-surveyed portions of the range. Although Anadarko is not currently active in the area, this survey will help guide any future development plans to ensure thoughtful siting of infrastructure to protect the lesser prairie chicken and its habitat.

Uinta Basin Hookless Cactus Reclamation Studies, Utah

Located in Anadarko’s Greater Natural Buttes field, the Uinta Basin hookless cactus is a threatened species under the ESA and the focus of an ongoing project with Utah State University in cooperation with the U.S. Fish and Wildlife Service to review and understand how mitigation and reclamation practices can be developed to benefit the species. Anadarko has committed $100,000 to this project, with an additional $300,000 pledged to further research species recovery.

Avian-Friendly Power Poles, Colorado

As Anadarko expanded the use of electricity to reduce emissions at new production facilities, we considered additional efforts to protect local birds and wildlife, specifically large predatory birds. By drawing on expertise from other areas in which Anadarko operates, avian-friendly clearances were incorporated into the power pole design. An eagle’s size and wing span clearance is taken into account when designing the vertical separation and horizontal clearance along with the use of fused cutout covers. Anadarko also installs a single fiberglass crossarm to discourage nesting. To provide additional protection, the center energized conductor is connected with an extended link to isolate the center phase from the two outer phases. Lastly, Anadarko is committed to burying conductor wires whenever feasible, further removing wildlife exposure to equipment.

Planning Around Sensitive Environments, Mozambique

Anadarko’s Mozambique Liquefied Natural Gas (LNG) project team has been working for the past four years to tailor its project layout to minimize potential impacts on local environments. Field studies conducted during the baseline phase of the Environmental Impact Assessment identified and mapped sensitive habitats for a variety of flora and fauna species, both onshore and offshore.

Using this sensitivity map as a guide, the project team investigated methods to avoid or minimize potential footprint and impacts. The resulting onshore project area of the LNG park effectively reduces the disturbance of sensitive areas from approximately 2,340 hectares (5,782 acres) to 1,695 hectares (4,188 acres).

By analyzing the original proposal in light of the sensitivity map, the project team identified an alternate route for the offshore pipeline corridor through a naturally degraded area. To further reduce potential impacts, the pipeline corridor through this less sensitive area was reduced from 300 meters (984 feet) to 100 meters (328 feet) in width.
