Operating Rules for Oil, Gas, and Other Geothermal Resource Wells (Hydrogen Sulfide Present)

Summary

This practice note discusses regulations that address wells that produce hydrogen sulfide. Most states have regulations in place to address this highly poisonous and corrosive gas. For the balance of this practice note, we will look at the regulation in Texas as a model state for oil and gas industry regulations nationwide. Similar rules can be found in other states as well (e.g., 25 Pa. Code § 78A.77). Hydrogen Sulfide is a naturally occurring gas that is sometimes present in natural gas, oil, or other minerals. It is highly poisonous, corrosive, flammable, and explosive. It is also heavier than air and colorless, making exposure extremely dangerous for the general public. While the Texas Railroad Commission requires an operator to burn such gas (known as flaring), it takes significant steps to regulate operators that deal with hydrogen sulfide to ensure the public is protected from inadvertent accidental exposure.
