Abstract: A system for sequestering carbon in a well includes a fluid waste processor configured to receive the fluid waste, to receive water, to separate solids from the fluid waste such that a separated fluid waste is generated, and to introduce the separated fluid waste and the water into a disposal well, a first sensor positioned at a first location and configured to measure a flowrate of the separated fluid waste and the water. The system includes a data processor configured to determine an amount of carbon sequestered in the well based on the flowrate measured by the first sensor and a hydrocarbon content of the separated fluid waste and the water, and a second sensor positioned at a second location in the fluid waste processor, the second sensor configured to measure a flowrate of the separated fluid waste but not a flowrate of the water.

Abstract: A portion of a drilling fluid waste is injected into a well. A cross-sectional dimension of solids in a slurry is reduced. The slurry includes the drilling fluid waste. A property of the slurry, of the well, or both is measured. A model is obtained based at least partially upon the property. The model represents an interaction of the slurry with the well. An additive is introduced into the slurry in response to measuring the property, generating the model, or both. The slurry is injected into the well after the additive is introduced.

Abstract: A method for injecting a portion of a drilling fluid waste into a well includes separating solids from the drilling fluid waste to produce a filtered drilling fluid waste. A cross-sectional dimension of at least a portion of the solids is reduced. The filtered drilling fluid waste is combined with the at least a portion of the solids that were reduced in dimension to produce a slurry. A property of the slurry is measured. The property is adjusted in response to measuring the property. The slurry is injected into the well.
