Abstract
An apparatus includes a sub-surface safety valve (SSSV) to be positioned in a wellbore. The SSSV is configurable to move between a closed position and an open position. While in the closed position, the SSSV prevents downhole fluid in the wellbore to flow to a surface of the wellbore. While in the open position, the SSSV allows the downhole fluid in the wellbore to flow to the surface of the wellbore. The apparatus further includes an electrostatic motor to be positioned in the wellbore and to be coupled to the SSSV. The electrostatic motor is to be selectively powered to move the SSSV between the closed position and the open position.
