Abstract
Methods and systems for creating fractures in a geological formation surrounding a well bore. In one implementation, a treatment material may be disposed at the bottom of the well bore. One or more propellant apparatuses may be immersed in the treatment material and a propellant may then be burned inside a first propellant apparatus to create fractures in the geological formation.
