The magnitude of risk is a function of the inherent hazard (toxicity) of the chemical and the level of exposure to it. Risk assessments provide regulators and risk managers with a mechanism for effectively protecting human health and the environment as part of chemical management. They can be utilized as a screening tool to identify if further action is required or to calculate the probability and magnitude of the adverse health effects through a comprehensive risk assessment process. This session will outline the elements of risk assessment and its importance to the oil and gas industry, while providing a foundation of knowledge for the remainder of the workshop and your future interactions with risk assessment.
Chairs: Amy Risen, MI SWACO; Bridget Todd, Baker Hughes
Good risk assessment requires good hazard assessment. Environmental science brings new tools to the table all the time. Which ones are we using to evaluate our chemicals? This session will focus on emerging science, technology, and methodologies that are applicable to the oil and gas industry. Both the currently used and emerging tools and techniques will be reviewed.
Chairs: Drue Ann Whittecar, National Oilwell Varco; Tom Parkerton, ExxonMobil
This session will highlight the key elements of exposure assessment of chemical substances, and how this information can be combined with hazard data to provide screening level substance risk assessments. [The need to identify how chemical emission sources to air, water, or soil over the lifecycle of a substance’s use, translate into multimedia exposures that can pose risks to human and environmental receptors will be discussed.] The various exposure pathways that contribute to a receptors exposure will be described. Additionally, the influence of substance properties and use pattern on the nature, magnitude, and uncertainty of a substance’s exposure will be highlighted from a modeling perspective.
Chairs: Stella Debord, BASF; Ziad Naufal, Chevron; Amy Risen, MI SWACO
Each industry has specific chemistries that present challenges from a product stewardship perspective. New chemistries pose questions of the appropriate way to assess them. In the E&P industry, these chemicals include biocides, surfactants, crystalline silica, nanomaterials, and byproducts such as produced water. This session will highlight challenges in developing products for a desired cost-performance while minimizing any health, safety and environmental risks. Also, novel methods being applied to certain chemistries that aren’t effectively assessed using traditional methods will be addressed.
Chairs: Jonathan Getliff, Chevron; John Candler, MI SWACO
This session will review the use of chemical risk assessment as per the different regulatory approaches and structures. For the eastern hemisphere, the application of chemical risk assessment in Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and regional discharge controls will be discussed. For the western hemisphere, the application of chemical risk assessment in the Toxic Substance Control Act (TSCA) and Canada’s Domestic Substance List (DSL) as well as discharge and remediation controls will be addressed. The eastern and western hemisphere approaches will be compared, contrasted, and discussed to identify similarities and gaps in the global regulation of chemical use in the oilfield.
Chairs: Kiran Srinivasan, Hess; Charles Ake, Baker Hughes
Hazard assessment is a fundamental component in risk assessment, and new regulatory and public perception challenges are requiring the industry to gain a deeper understanding of hazards and risks associated with chemical products. Recent movements of international organizations sponsored by the United Nations (UN) have addressed hazard communication through GHS. The adoption of this system has brought about an international consensus to hazard evaluation. Although the intended scope of GHS focuses on standardization of hazard communication and challenges remain in maintaining harmonization, its core elements of hazard assessment may be useful as the foundation of a uniform and industry-coordinated hazard and risk assessment system.
Chairs: Fernando Sierra, Shell; Ana Djuric, Halliburton
This session will review emerging regulations related to E&P chemicals risk and hazards in the United States and other countries. REACH is a regulation of the European Union, adopted to improve the protection of human health, and the environment. Many countries are attempting to integrate chemical models within the complexities of their own regulations to promote risk evaluations and economic growth. One such country is the United States with proposed TSCA reforms that are continuously in the forefront of political debates. In parallel, GHS was originally intended to harmonize and globalize hazard communication. As the GHS roll-out continues, interpretation and chemical disclosure on Safety Data Sheets (SDS) shows evidence of divergence in each jurisdiction. The session will present a snapshot in time of the direction regulatory regimes are taking.

Effective communication of unfamiliar concepts and complex information that describe chemical risks is an important step for the E&P industry to gain their “license to operate” from public stakeholders. Presenters will provide valuable, experience-based guidance and examples that will assist participants in developing messages that can communicate complex information in terms that are relevant and useful to key stakeholders.
