Abstract
An apparatus for injection of a gas into aquifer is described. The apparatus includes a gas generator that generates gas such as ozone for injection into the aquifer. The apparatus includes a casing and a packer disposed through the casing. An air injection passageway disposed through the packer and coupled to the gas generator. A pump is disposed within the casing and have an inlet above the packer and an outlet below the packer. The casing has an outlet screen that has a pore size less than about 200 microns. The apparatus has a microporous diffuser coupled to the gas generator, said microporous diffuser including a body having a porous portion with a pore size less than about 200 microns.
Claims41
Apparatus for injection of a gas into aquifer regions, comprises:
- a gas generator that generates gas for injection into the aquifer;
- a casing;
- a packer disposed through the casing;
- an air injection passageway disposed through the packer and coupled to the gas generator;
- a pump disposed within the casing and having an inlet above the packer and an outlet below the packer;
- an outlet screen coupled to the casing;
- and
- a microporous diffuser coupled to the gas generator, said microporous diffuser including a body having a porous portion with a pore size less than about 200 microns.
A well casing, comprising:
- a well-screen diffuser disposed to form part of the casing, said well-screen diffuser having a porosity in the range of about 5 microns to 200 microns.
Apparatus for injection of an air/ozone mixture into aquifer regions, comprises:
- a gas generator that generates ozone gas for injection of the air/ozone gas into an aquifer;
- a microporous diffuser coupled to the gas generator, said microporous diffuser comprising:
- a tubular body having a pore size that is matched to pore size of surrounding material that the microporous diffuser is introduced into.
