Abstract
A hydraulic arrangement for fail-safe and pump-through of a safety valve. The arrangement allows for compact actuation of a safety valve through accumulators. The arrangement supports automatic closure of the valve in the emergent circumstance of any loss of hydraulic control above the valve. Additionally, the arrangement also allows for a technique of re-opening the valve for long term killing of a well in direct response to the introduction of kill fluid without requiring any added complex interventional measures.
