Abstract
A well system having a galvanic time release plug. A well system includes a flow passage and a flow blocking device which selectively obstructs flow through the passage, the device including an electrode in a galvanic cell. A flow blocking device for use in conjunction with a subterranean well includes a portion which delays an electrochemical reaction in a galvanic cell. A method of controlling fluid flow in a well system includes the steps of: obstructing flow through a passage using a flow blocking device which includes an electrode of a galvanic cell; and increasing flow through the passage by operation of the galvanic cell.
