Abstract
Official abstract text for this publication.
Methods and fluids are provided that include, but are not limited to, a drilling fluid comprising an aqueous base fluid and a fluid loss control additive that comprises at least one polymeric micro gel and a method comprising: providing an aqueous based treatment fluid comprising a fluid loss control additive that comprises at least one polymeric micro gel; placing the aqueous based treatment fluid in a subterranean formation via a well bore penetrating the subterranean formation; allowing the fluid loss control additive to become incorporated into a filter cake located on a surface within the subterranean formation; allowing the filter cake to be degraded; and producing hydrocarbons from the formation. Additional methods are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: providing a treatment fluid comprising an aqueous base fluid and a fluid loss control additive, wherein the fluid loss control additive comprises at least one at least partially spherical, non-fibrous polymeric micro gel that comprises a reaction product formed by a polymerization reaction of a polymer or copolymer and a crosslinking agent, wherein the polymer or copolymer comprises at least one unit based on at least one compound sel…
