Abstract: An electric drive valve control and safety system for application in gas injection gas lift valve in oil production column, which guarantees the gas lift (GL) operation and provides fail-safe-close, with greater reliability in the safety conditions of the joint sets of safety barriers (JSB), further enabling the integration of sensors for monitoring the conditions of the gas lift valve (GLV), the gas lift (GL) operation and the safety of the joint set of safety barriers (JSB).

Abstract: A fully electric tool for continuous downhole flow control is described, said tool comprising a body and along the said body, actuating set(s), each actuating set comprising a passage system comprised of shaft(s) radially disposed along said cylindrical body, each of said shaft (s) being actuated with its opposed pair or in an independent way in a well-defined position or not, said shaft(s) being provided of spherical element(s) or sphere(s), provided of at least one window forming piles of sphere(s) in shaft(s), the rotation of said shaft(s)(108) of piles of sphere(s) enabling the opening or total or partial obstruction of holes by the total or partial coincidence of said window(s) of sphere(s) with said bore(s) of said cylindrical body.
