A technique facilitates wellbore operations and utilization of wellbore equipment, e.g. equipment comprising actuation devices for downhole tools. According to an embodiment, the system comprises a pump solution for an electrically control device, e.g. an electrically controlled valve. The system may comprise hydraulic circuitry which utilizes bellows to effectively enclose the hydraulic circuitry. Consequently, the system enables an electrically control downhole system having components hydraulically actuated via a closed loop hydraulic system.

System and method for electro-hydraulic actuation of downhole tools

An apparatus includes a circuit to receive power and data over a communication medium, where the circuit is to separate the power and the data. An electronic switch couples the power output by the circuit to a downhole electrical component for use in a well. According to other implementations, an electro-hydraulic actuator includes an outer housing defining a first hydraulic chamber and a second hydraulic chamber, where a seal for one of the hydraulic chambers is achieved without use of an elastomeric seal.
