The HMS encompasses a comprehensive set of policies, business practices and procedures to reduce our energy usage and GHG emissions, improve water quality and conservation, use chemicals in environmentally safe ways, decrease waste, and protect the quality and biodiversity of our environment.
Halliburton also uses the HMS to establish environmental management practices in our supply chain, including compliance with mandatory COBC training and with additional HSE training that is required of certain suppliers. Expectations around, and mechanisms for, monitoring the ESG performance of our suppliers are described in more detail in the Supply Chain Chapter.
Environmental incidents across all areas of our operations are managed using the same methodology as for health and safety incidents, following the HSE and SQ incident management process described in the Health and Safety Chapter. Environmental incidents are included in our statistics, along with fines associated with any regulatory noncompliance.
The majority of reported incidents are spills that occur at Halliburton facilities and field locations across the globe. In 2020, we continued to improve how spills are evaluated in order to align with industry norms. Halliburton is committed to minimizing its environmental impact, and the Company monitors spill trends and investigates spill incidents defined as significant to identify areas for process improvement and to implement corrective actions.
In 2020, we had no significant environmental noncompliance spill incidents and no significant environmental fines.
Our Environmental Improvements Sustainability Commitments:
- 40% Scope 1 & 2 reduction by 2035 from 2018 baseline.
- Partner with Tier 1 suppliers to track and reduce Scope 3 GHG emissions.
- Establish and achieve waste-reduction targets in our major facilities.
- Create water use improvement plans in our major facilities located in water-stressed areas.
Chemical stewardship is a critical part of our responsible management of environmental impacts of the products and services we provide to our customers worldwide. Halliburton is recognized as an industry leader for the digitization of our Safety Data Sheet (SDS) data and its integration into our Chemical Stewardship Management System (CSMS).
We create value for our customers and communities through the use of automated regulatory tracking alerts that are integrated into chemical import and export transactions globally. Our proactive impact analysis of risk helps support sustainable market development.
In 2020, we launched new workflow management tools as part of our CSMS that will further strengthen our procedures to purchase, use, distribute and develop chemical products in a manner that promotes safety and sustainability throughout their life cycle.
The key elements of our CSMS include:
All Halliburton chemical products are backed by an SDS that complies with the latest regulatory requirements, including the Globally Harmonized System of Classification and Labeling of Chemicals. All SDSs are available through our website.
- Our Chemistry Scoring Index (CSI), a risk assessment process that compares the relative risks associated with the use of Halliburton chemical products in oil and gas operations. Using the CSI, our customers can compare Halliburton chemical products within the same class of use and application, enabling them to choose products that optimize performance and minimize potential HSE risks.
- Detailed information regarding the chemical constituents of our hydraulic fracturing fluids is provided to customers on the Halliburton website to assure compliance with state laws, as well as with voluntary standards established by the FracFocus chemical disclosure registry, of which Halliburton is a founding member.
Our Multi-Chem PSL is a full-service specialty chemical provider for the stimulation, production, and downstream oil and gas markets. Along with its complete chemical portfolio, Multi-Chem has deployed chemical programs that enable customers to improve the environmental footprint of their operations. In one instance, our Multi-Chem Friction Reducer program enabled a customer in the Northeast U.S. to reuse more than 100 million gallons of produced water that would have otherwise been disposed of and replaced with fresh water.
Multi-Chem also offers FightR® LXD dry friction reducers that eliminate hydrocarbon carriers in typical friction reducers, while providing improved performance, cost savings, and mitigation of HSE risks. Our Multi-Cide™ program replaces common oxidizers with lower-vapor-pressure biocide options to reduce chemical emissions while protecting against microbial contamination and well souring in hydraulic fracturing operations.
Launched this year, Multi-Chem’s platform for digitizing our oilfield chemical operations, APX™ (Analysis of Performance eXecution), provides real-time transparency and interpretation into chemical operations through field and laboratory data to report on activities and performance. One key feature of this platform is its ability to automate the chemical ordering process, allowing for optimization of delivery routes. As the application reaches scale, order automation and improved route visibility and planning will reduce over-the-road chemical hauling by eliminating unnecessary trips, improving our emissions profile, and reducing risks related to handling and transporting chemicals on public roadways.
Water and Effluents
We are committed to working with our customers to reduce their water usage. Because water used at hydraulic fracturing sites and at wellsites in activities such as cementing and drilling is purchased and controlled by our customer, it is not part of our reporting scope. However, we have developed new chemistries and separation technologies that enable the recycling of flowback water to be used in a wide range of geographies, thus replacing the need for fresh water typically used in these operations.
Our reported data on water usage includes water used at Company-owned or leased business operations, and covers 100 percent of our U.S. facilities and our major global facilities. Major global facilities are manufacturing facilities or any location having a building footprint larger than two acres, and housing those activities identified as being the largest potential users of water. These facilities account for 57 percent of our global building footprint.
In 2020, Halliburton focused on further classifying water usage in water-stressed areas. This data will enable us to build upon our internal focus to conserve water at Halliburton facilities, prioritizing those locations that are deemed at risk by being in water-stressed areas.
Many of our locations are already implementing water-reduction projects. These projects include the optimization of HVAC systems and the recycling of water used for process cooling, vehicle washing, chemical blending and landscape irrigation.
The streamlining of our field-based maintenance operations has not only reduced emissions but also enabled a reduction in tank cleanings and function test time at our facilities. These changes have resulted in an estimated annual decrease in water usage of 1,265,000 gallons.
Our Taloja, India, facility is a zero-discharge facility, thanks to the installation of an emulsion treatment plant and a sewage treatment plant, which enables complete recycling of wastewater.
Two of our manufacturing facilities in Alaska worked together on a project that resulted in the reuse of 8,700 gallons of water per year. Our Nitrogen Production Solutions plant produces condensation water during heating and cooling phases that is collected in containers and was previously tested and trucked to a disposal well. Exploring alternative uses for this water, we found that a nearby Baroid manufacturing facility needed water on a regular basis and would be able to use the condensate water. In addition to the environmental benefits of reusing the water, we realized savings from the elimination of testing and disposal costs.
Halliburton facilities in Ecuador, Colombia and Brazil have effluent treatment stations to process industrial wastewater, which passes through physical, chemical and microbiological treatment and is then reused. The effluent treatment station at our plant in Macaé, Brazil, treats and recycles 30 cubic meters of water per day on average.
Halliburton is committed to reducing the amount of waste generated at our facilities. We have developed waste minimization and management plans to help us achieve that commitment. Waste is generated from our offices, workshops, field camps and manufacturing facilities, as well as from wellsite operations that Halliburton has control over. Our facilities follow all applicable laws and regulations for waste storage, treatment and disposal, including hazardous waste storage and disposal, and we perform audits of service providers used for waste management services to ensure compliance.
Waste management standards are part of the Halliburton Management System, and include waste minimization guidelines designed to reduce environmental impact and waste disposal costs. These guidelines include source reduction practices, such as modifying equipment or reformulating products to reduce waste and toxicity.
Global facility closures/consolidations due to market conditions resulted in a waste disposal increase.
Emissions impacts from material landfilled, recycled and composted. Blue indicates the emissions reduced from recycling and composting, while red indicates emissions from landfilling.
Our data on waste generation covers:
- All U.S. locations
- All manufacturing locations
- Any non-U.S. location having a building footprint larger than two acres (8092 m2) and housing those activities identified as having the largest potential for waste generation
Our recycling and reuse initiatives include reclamation of equipment as it approaches its end of life. Each major equipment component is investigated and dispositioned according to sustainable standards, such as being returned to the field, sent to be rebuilt at an Original Equipment Manufacturer distributor, or sold to be recycled.
Halliburton Drill Bits & Services
Halliburton Drill Bits & Services (HDBS) recycled approximately 75 percent of its waste in 2020, providing significant benefits by diverting the amount of waste sent to landfills and reducing waste disposal costs. HDBS recycled approximately 263,153 pounds of graphite powder and chunks, along with 780,400 pounds of steel turnings, 1,411 pounds of carbide powder and inserts, and 71,115 pounds of matrix shavings.
Our commitment to environmentally sound and sustainable business practices includes protecting the biodiversity of the land where we operate. As a service provider, our impact on biodiversity and land disturbance is limited to the development of our offices, field camps, chemical facilities and service centers. Our customers are primarily responsible for developing wellsites and leasing roads. As such, we work with them to minimize impacts, but they have more control over any subsequent impacts
on biodiversity and disturbance of land.
We are cognizant of the impacts of transportation and our equipment in the field, and, as such, in 2020, we drafted a biodiversity policy that consolidates required mitigation efforts and management approaches.
