Inactive Well Program Concepts

The API inactive well program is a risk-based approach for determining if an inactive well poses a threat to fresh water aquifers, surface soils, or surface waters. The methodology described in the following sections identifies wellbore conditions that prevent fluid migration from pressured formations. Fluid migration potentials for inactive wells are defined based upon the presence of pressured formations and upon the well construction and its mechanical integrity.
