An expandable wirefinder () for locating a wire downhole comprises a sleeve () and a dual collet assembly (). The dual collet assembly () has first and second collet members () each having plurality of collet fingers (). The dual collet assembly () is slidable relative to the sleeve () to operate between running and finding positions. In the running position, the first collet member () is partially disposed within the sleeve () with its collet fingers () inwardly radially biased by the sleeve () and the second collet member () is disposed within the first collet member () with its collet fingers inwardly () radially biased by the sleeve (). In the finding position, the collet fingers () of the first collet member () radially expand to form gaps therebetween and the collet fingers () of the second collet member () radially expand into the gaps.

Expandable wirefinder and method for use of same

Apparatus and associated methods are provided for remotely actuating a plug apparatus in a subterranean well. In a described embodiment, a plug apparatus has a plug member blocking fluid flow through one of two flow passages of the plug apparatus. A predetermined fluid pressure applied to one of the flow passages permits the plug member to be expended from the plug apparatus.
