100 Series — ABANDONED WELL

ABANDONED WELL

A well is considered abandoned if its use has been permanently stopped, or if it's in such bad condition that it can't be used for its original purpose or even for observation.

100 Series — ALLOCATED GEOTHERMAL RESOURCE

ALLOCATED GEOTHERMAL RESOURCE

This is a definition. An Allocated Geothermal Resource is any geothermal resource that is associated with nontributary groundwater, but it does not include groundwater in the Denver Basin Aquifers.

100 Series — ANCILLARY HEAT PRODUCTION

ANCILLARY HEAT PRODUCTION

Definition: Ancillary heat production is using heat from produced fluids at an oil and gas operation to cut emissions at the same location where the well is, and only when that heat wouldn't make economic sense as a standalone geothermal project.

100 Series — ANNULAR OVER-PRESSURIZATION

ANNULAR OVER-PRESSURIZATION

Annular over-pressurization is when fluids trapped between the surface casing and the intermediate or production casings build up enough pressure that they might leak or migrate out of that annular space.
