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.
Claims20
A method for creating fractures in a geological formation surrounding a well bore, comprising:
- disposing a treatment material at the bottom of the well bore;
- immersing one or more propellant apparatuses in the treatment material;
- and
- burning a propellant inside a first propellant apparatus to create fractures in the geological formation.
A system for creating fractures in a geological formation surrounding a well bore, comprising:
- a treatment material disposed at the bottom of the well bore, wherein the treatment material comprises at least one of acid, chelant, solvent, surfactant, brine, oil, and enzyme;
- and
- a propellant apparatus immersed in the treatment material.
A propellant apparatus, comprising:
- a carrier;
- a propellant disposed inside the carrier;
- and
- a treatment material imbedded inside the propellant, wherein the treatment material comprises at least one of acid, chelant, solvent, surfactant, brine, oil, and enzyme.
A propellant apparatus, comprising:
- a carrier;
- a propellant disposed inside the carrier;
- and
- a treatment material coating an outside surface of the propellant, wherein the treatment material comprises at least one of acid, chelant, solvent, surfactant, brine, oil, and enzyme.
A propellant apparatus, comprising:
- a carrier;
- a propellant disposed inside the carrier;
- and
- a treatment material coating an inside surface of the carrier, wherein the treatment material comprises at least one of acid, chelant, solvent, surfactant, brine, oil, and enzyme.
A propellant apparatus, comprising:
- a carrier;
- a propellant disposed inside the carrier;
- and
- a treatment material coating an outside surface of the carrier, wherein the treatment material comprises at least one of acid, chelant, solvent, surfactant, brine, oil, and enzyme.
