Abstract

See full text

A method for actuation of a downhole device includes rotating a drill pipe relative to a cylindrical pipe disposed coaxially within the drill pipe. First segments including a first material are disposed on the inner surface of the drill pipe. Second segments including a degradable material are disposed on the outer surface of the cylindrical pipe, with each of the second segments aligned with a corresponding first segment. The first material and the degradable material are insoluble in the downhole fluid, and a solubility of the degradable material in a solvent is greater than a solubility of the first material in the solvent. The method includes generating a first electrical signal pattern during rotation of the drill pipe; introducing the solvent into the drill pipe, in which the degradable material degrades responsive to introduction of the solvent; and generating a second electrical signal pattern after introduction of the solvent.
