Effect of CO2 on the Integrity of Well Cement under Geologic Storage Conditions

Geologic carbon storage is the separation and capture of carbon dioxide (CO2) from large stationary sources, such as power plants, followed by injection into deep geologic formations. Long-term storage of CO2 pre-supposes very low or no leakage from the formation. The majority of locations that are being considered for CO2 injection are in areas that have a history of oil, natural gas, and/or coalbed methane production, and are typically penetrated by asignificant number of wells from exploration and production. The ability to effectively store large quantities of CO2 may be compromised by the presence of these active or abandoned wells, which represent potential leakage paths. 

LiDAR Technology Enables the Location of Historic Energy Production Sites

Understanding the impact that newly developed novel methods for extracting resources from the Earth has on our environment is important, but this requires baseline data against which potential changes can be measured. In Pennsylvania, as in other parts of the United States, commercial activity has already left environmental impacts that are not readily discernible.
