Abstract

Downhole tools and methods are provided for injecting fluid into a formation. A downhole tool may include a first chamber of injection fluid separated from a second chamber of working fluid by a piston. The working fluid may be employed to apply pressure to the piston to direct injection fluid from the first chamber to the formation. A flow regulator may regulate flow of the injection fluid from the first chamber to the formation.
