Abstract
An enhanced oil recovery method and apparatus for thermal processing of polymer-based waste to produce organic and inorganic processed materials. The organic and inorganic processed materials are injected as an injection stream into the ground to liberate ground oil. The liberated ground oil is withdrawn from the ground. The injection stream interacts with the ground oil to form a new oil and the new oil including the ground oil is withdrawn from the ground. Thermal processing is done with pyrolysis of waste tires.
Claims30
A method of enhanced oil recovery comprising,
- thermal processing polymer-based waste at temperatures higher than approximately 200° C. to produce organic and inorganic processed materials,
- injecting the organic and inorganic materials as an injection stream into the ground to liberate ground oil,
- withdrawing the liberated ground oil from the ground.
A method of enhanced oil recovery comprising,
- thermal processing polymer-based waste, wherein the waste is tires, to produce organic and inorganic processed materials,
- injecting the organic and inorganic materials as an injection stream into the ground to liberate ground oil,
- withdrawing the liberated ground oil from the ground.
A method of enhanced oil recovery comprising,
- thermal processing polymer-based waste to produce organic and inorganic processed materials, wherein the thermal processing step is performed with a pyrolysis apparatus,
- injecting the organic and inorganic materials as an injection stream into the ground to liberate ground oil,
- withdrawing the liberated ground oil from the ground.
A method of enhanced oil recovery comprising,
- thermal processing tire waste to produce organic and inorganic processed materials including solids, liquids and gases,
- injecting at least the liquids and gases of the organic and inorganic materials as an injection stream into the ground to liberate ground oil,
- withdrawing the liberated ground oil from the ground.
