<p>Disclosed is a system for the remote control of operation control means, such as valves, that are arranged in a well to control the recovery of gas and/or oil from the well, said remote control system comprising a first system part located outside the well and connected to a second system part which is located in the well and operatively connected to the operation control means. The system according to the invention is characterized in that all semiconductor components comprised in the system are housed in the first system part, while the second system part houses electromechanical components (d1-d7; D2-D7) that actuates the operation control means (S1-S7) upon command from the first system part. Disclosed is also a method for the remote control of down-hole operation control means in an oil and/or a gas well completion, comprising the steps of i) equipping a first system part located outside the well with all semiconductor components that are comprised in the system, and ii) equipping a second down-hole system part with electromechanical components that are actuated from the first system part for actuation of the operation control means.</p> |
