Completing an EPA Class VI Well Permit Application? Here’s the Information You’ll Need to Aggregate.

An EPA Class VI Well Permit is required for the injection of  CO2 into the ground. The application process for this type of permit can be complex and time-consuming, but it’s a necessary step to ensure the safety of our environment and public health. In this blog post, we will provide an overview of the information you need to gather to complete an EPA Class VI Well Permit application.


1. Well Location

The first piece of information you’ll need is the location of the well. This includes the surface latitude and longitude of the well, the subsurface wellbore path, and information about offset wells in the surrounding area. It’s important to provide accurate information about the well location to ensure compliance with regulations and to protect public health and the environment.


2. Injection Volume, Rate, Pressure and Source of CO2 Injectate 

The estimated volume and rate of CO2 that will be injected into the well is another important piece of information you’ll need to provide. Further, you will also need to provide the estimated pressure of injection and the source(s) of the CO2. This information is used to ensure that the well is designed and constructed to handle the anticipated volume of CO2 and to ensure compatibility with the intended injection zone. 


3. Well Construction Details

Detailed information about the downhole construction of the well is also required for a Class VI Well Permit application. This includes the depth of the well, the size and grade of all the casing strings, and the type of cement to be used. You’ll also need to provide information about any other equipment to be used including packers, deviation tools, tubing or appropriate testing devices. 


4. Geological Reports

Geological reports are a critical part of the Class VI Well Permit application process. These reports provide detailed information about the geological and hydrogeoloical conditions of the area, geomechanical information relevant to the proposed injection zone, and seismic history of the area. The EPA will use this information to assess the potential risks associated with the well and to ensure that the well is constructed and operated safely.


5. Operational Plans

Proposed plans for pre-operational formation testing, stimulation of the injection zone (if applicable), the injection process, and testing and reporting for the duration of the  injection process are also required for a Class VI Well Permit application. This includes details on how the well will be completed and how the CO2 will be injected, monitoring equipment and procedures, the frequency of testing, and data reporting requirements. The monitoring plan is designed to ensure that the well is operating safely and to detect any potential issues early on.


6. Emergency Response Plan

Finally, you’ll need to provide an emergency response plan that outlines actions to be taken in order to address any potential migration of the injected CO2 into unintended areas.The plan must address a process for immediate cessation of injection, a remedial response plan, and EPA notification of potential USDW endangerment. This plan is critical for ensuring that any incidents are handled quickly and effectively, minimizing the impact on public health and the environment.


The Class VI Well Permit application process requires a significant amount of information gathering and documentation. By providing accurate and complete information, applicants can ensure that their application is processed efficiently and that the well is designed and operated safely. It’s important to consult with the EPA to ensure that all requirements are met and that the application is completed correctly.
