..., estimating a reasonable range for the effective well permeability of the disturbed zone remains a challenge. For this study, a more than 1-sq-mile section in the Wattenberg Field of the DJ Basin was used. The goal was to quantify the leakage rate when carbon dioxide (CO 2 ) escapes through a well 1,100 ft...

For CCS, we do a subset of this; we work out where we can safely store CO 2 , we decide how many wells to drill, we...

... of the fight against climate change, natural gas is seen as a great enabler of the energy transition to nonemitting sources. Experts believe natural gas could help drastically reduce greenhouse gas (GHG) emissions by replacing coal—when burned, it emits about half the carbon dioxide (CO 2 ) compared to coal...
