If your worksite is planning a sour gas well abandonment project, you need the right tools to provide a secure seal and maintain a hazard-free environment around your old wellsite. Permanent bridge plugs help prevent issues like fluid migration and sour gas leaks, and are essential to any well abandonment project. Keep reading to learn more about the ins and outs of working with sour gas and how our wireline tools from Avalon Research can help provide advanced well control.
What Is a Sour Gas Environment?
Sour gas is a natural gas that contains a significant amount of hydrogen sulphide (H2S) and carbon dioxide (CO2). It has highly acidic and corrosive properties, which is why it’s referred to as “sour.” This gas is corrosive due to its high H2S content (more than 1% by volume).
This highly hazardous gas is commonly found in oil wells, largely due to the breakdown of organic materials in gas, oil, sewage, and other geological matter.
Oil sites operating in sour gas environments require tools made from durable, corrosion-resistant materials such as carbon steel, stainless steel, and nickel alloys. This ensures the safety and security of sour gas well sites during snubbing operations, suspensions, and well abandonment projects.
Health and Environmental Risks of Improperly Abandoning Sour Gas Operations
Sour gas is a highly hazardous material that, if not properly controlled, can have serious ramifications for worker and public health, as well as for the environment.
H2S exposure can cause a range of issues, from eye irritation to death in more severe circumstances. Environmental risks include soil and water contamination and gas flaring. The release of S02 into the atmosphere can even lead to air pollution and acid rain.
Worksites that deal with sour gas take these risks very seriously. Oilfield operators are careful to supply their jobsites with tools and equipment that can safely operate in sour gas environments.
Well abandonment projects where sour gas is present have the potential to create an environmental hazard. Improper well sealing can cause sour gas leaks, which can lead to any number of unprecedented environmental and public health crises.
To prevent sour gas leaks and maintain well integrity, oil sites use permanent bridge plugs designed to safely secure sour gas environments. These plugs allow oil sites to complete their sour gas recovery work and close the book without creating a hazardous area.
