IMPLEMENTING TANKLESS DESIGN SOLUTIONS
One of our most transformative innovations is the tankless design, now implemented across many of our greenfield and brownfield battery projects. This design replaces traditional atmospheric storage tanks with pressurized surge vessels, maintaining similar process flows and liquid retention times. Surge vessels do not require high-risk pressure protection devices such as thief hatches and vent stacks. Instead, they utilize spring-loaded, bubble-tight pressure relief valves, significantly reducing the potential for emissions leaks. The design also directs gas flow from hung separator dumps to flare, not vent.
EMISSIONS REDUCTION & PERFORMANCE GAINS
Our tankless design has delivered substantial environmental and operational benefits such as ~70% reduction in facility emissions, ~25% improvement in vapor capture efficiency over legacy designs, and significant reduction in methane release risk. These improvements reflect our commitment to proactive, data-driven solutions that address core emission sources.
SCALABILITY & IMPLEMENTATION
In 2020, we transitioned all in-flight projects to the tankless design, bringing our first facility online in Q1 2021. Since then, we’ve commissioned over 50 tankless facilities, now covering approximately 60% of our oil production. Our designs have scaled to accommodate multiple leases, with facility capacities reaching40,000 BOPD, 160,000 BWPD, and180 MMSCFD This scalability ensures operational efficiency across diverse production environments.
REGULATORY ALIGNMENT & RISK MITIGATION
With new regulations, our tankless approach offers a strategic advantage. By eliminating these tanks, we’ve preemptively removed what would have become one of our top emission sources. These measures help avoid triggering OOOOb Super-Emitter thresholds, reinforcing our commitment to responsible operations. With new regulations, our tankless approach offers a strategic advantage.

PROGRAM EXPANSION & FUTURE INNOVATIONS
Coterra continues to expand the tankless program to include low-producing, high-emission-risk facilities. We’ve developed smaller, cost-effective vertical surge vessels tailored for these sites, enabling broader adoption. Most recently, we’ve extended tankless solutions to our newest compressor stations, supporting natural gas liquid storage with the same emissions-reducing benefits.
