Solving the Produced Water Reclamation Problem
The cost of disposing of produced water poses a significant challenge for oil companies. Traditionally, common methods such as underground injection and evaporation ponds have been employed, but they come with high costs. These costs include transportation, treatment, and the construction of disposal infrastructure. Furthermore, the costs of compliance with ever-evolving environmental regulations add to the financial burden.
Produced water, emerging as the largest waste stream from oil and gas production, presents both challenges and opportunities for the industry. The volume of this water is substantial, with 15 to 20 billion barrels generated annually in the U.S. alone. The states of Texas, California, Wyoming, Oklahoma, and Kansas are the top contributors, accounting for nearly 75% of the total U.S. production of produced water.
​
In terms of disposal costs, they can vary based on the method of disposal and the region. Costs for disposal range from $5.00 per barrel (bbl) to $14.00/bbl. Some companies have also ventured into recycling produced water, with costs reported as $5.00/bbl in California and $25.00 per load in Oklahoma. The large volumes of wastewater generated in the industry are primarily managed through underground injection, a method where the water is injected back into the ground and becomes inaccessible for future use.
Considering the vast volumes of produced water and the associated disposal costs, the market for disposal of produced water is significant. In fact, based on the previous analysis the total market value is between $75~$280 billion annually. And with the ongoing exploration and production activities, coupled with regulatory requirements, the demand for efficient and cost-effective disposal methods will continue to grow.
Impact of EPA and Other Regulations
The Environmental Protection Agency (EPA) plays a pivotal role in regulating the disposal of produced water in the oil and gas industry. Their regulations are designed to ensure that the environment is protected from potential contaminants and that the water is treated to a standard that minimizes harm.
Extended Producer Responsibility (EPR) is a strategy that adds all estimated environmental costs associated with a product throughout its life cycle to its market price. In the context of the oil and gas industry, this means that companies are financially responsible for the environmental impact of their produced water from extraction to disposal[1]. This can significantly influence the disposal costs of produced water, as companies must factor in the entire lifecycle costs of their waste.
Moreover, with the rise of ESG (Environmental, Social, and Governance) considerations in the investment world, companies are under increasing pressure from shareholders to demonstrate sustainable practices and regulatory compliance[2]. This further emphasizes the importance of adhering to EPA and other environmental regulations, not just to avoid penalties but also to attract and retain investors.
While regulations like those from the EPA can increase the immediate costs of produced water disposal for oil and gas companies, they also drive innovation in water treatment solutions. Companies that can exceed these regulations, like Neptune, position themselves as industry leaders, offering cost-effective solutions that are both environmentally friendly and compliant. This not only ensures sustainable operations but also helps in maintaining a positive public image in an increasingly environmentally-conscious world.
