Downhole control arrangement, valve arrangement, side pocket mandrel, and method for operating a downhole valve arrangement

A side pocket mandrel for installation in a production tubing for use in a hydrocarbon well, wherein the side pocket mandrel comprises:

• an interior pocket space;
• a valve arrangement comprising an electrically controlled control valve and a controller having a processor, the valve arrangement being located in the interior pocket space for controlling the flow of an injection fluid from an external injection fluid source into the production tubing;
• and
• an induction coil arrangement connected to a topside controller and connected to the valve arrangement for transmission of signals from the topside controller to the valve arrangement or vice versa and/or for transfer of electric power from the topside controller to the valve arrangement,
• wherein the valve arrangement comprises an actuator, wherein the induction coil arrangement is configured to send signals from the topside controller to the controller and vice versa, the actuator is configured to move the electrically controlled control valve of the valve arrangement between an open position and a closed position based on the signals,
• wherein the actuator is configured to send signals to the controller with information about the open/closed status of the electrically controlled control valve,
• wherein the side pocket mandrel further comprises:
• a recess provided in an external wall part of a first side wall, and the recess reaches a first compartment, and the recess is configured to receive a first induction coil of the induction coil arrangement for insertion into the first compartment;
• and
• a lid configured to cover the recess.
