Abstract
Official abstract text for this publication.
The current invention relates to the use of chitin nanocrystals and chitin nanocrystal derivatives. More specifically, the present invention relates to the use of chitin nanocrystals and chitin nanocrystals used in oil and gas operations. The chitin nanocrystals and chitin nanocrystals derivatives can be used as additives to cement and wellbore fluids and can be used to inhibit corrosion in pipelines, on downhole tools and on other oil and gas related equipment.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for treating a wellbore comprising: circulating a wellbore fluid in said wellbore, wherein said wellbore fluid comprises a fluid and at least one additive selected from the group consisting of chitin nanocrystals, chitin nanocrystal derivatives and combinations thereof; wherein the chitin nanocrystals and chitin nanocrystal derivatives are substantially free of amorphous components, and wherein said chitin nanocrystals are primarily comprised of chi…
