Abstract
This disclosure relates to methods and systems for injecting and/or sequestering carbon-containing materials in underground wells, and, in some examples, for using the carbon-containing materials for enhanced oil recovery and well abandonment. An example method includes: obtaining a mixture including biochar particles and a liquid; and providing the mixture for injection into an underground well.
Claims24
A method of sequestering carbon-containing materials, the method comprising:
- obtaining biochar;
- compressing the biochar to increase a density of the biochar;
- combining the biochar with a liquid to obtain (i) a mixture comprising a first portion of the biochar dispersed in the liquid and (ii) a second portion of the biochar floating on the mixture;
- separating the second portion of the biochar from the mixture;
- and
- providing the mixture for injection into an underground well.

A system for sequestering carbon-containing materials, the system comprising:
- a source of biochar;
- a compression device for compressing the biochar to increase a density of the biochar;
- a mixing device for combining the biochar with a liquid to obtain (i) a mixture comprising a first portion of the biochar dispersed in the liquid and (ii) a second portion of the biochar floating on the mixture;
- a separation device for separating the second portion of the biochar from the mixture;
- and
- at least one of a container, a pump, or a pipe for injecting the mixture into an underground well.
