    Overview

    The Mechanical Integrity Assessment (MIA) is a process used to review and record well integrity data for oil and gas wells every three months. This review is required by law.

    • For conventional wells: Only one of the quarterly inspection results needs to be reported each year.
    • For unconventional wells: All four quarterly results must be reported each year.

    Note: This rule does not apply to:

    • Underground gas storage wells
    • Wells marked as inactive
    • Wells regulated by the EPA’s Underground Injection Control Program

    These types of wells are monitored under different rules in Chapter 78.

    Annual Reports: Wells that need an MIA must submit their annual reports to the Department by February 15th of the year following the inspections. You can find MIA annual reporting forms, instructions, a user guide, and other helpful information by clicking the link below.
