How is a gas well characterized?

A gas well is characterized as a well that may be active, abandoned, or plugged because these conditions reflect the various states a gas well can be in throughout its lifecycle. An active well is one that is currently producing gas, while an abandoned well signifies that it is no longer in use but may still exist physically in the landscape. A plugged well indicates that the well has been sealed off to prevent any potential hazards or environmental issues, such as gas leaks.

This understanding is crucial for managing gas wells responsibly, as each status requires different regulatory approaches and safety measures. The other options do not accurately encompass the definition of a gas well: some are focused on oil extraction, others on specific types of mining or water supply, which do not fit the broader characteristics of gas wells.
