Excelsior has been working with EPA to amend its UIC permit to include well stimulation and the Company expects the amendment to be finalized early in 2023.

Excelsior’s proposed well stimulation is shallow, low-energy, and is not like “fracking” that is commonly undertaken in the energy sector.

All the injection fluids just become part of the normal processing stream, captured by the recovery wells, so there are no waste products.
