RETRIEVABLE WELL BORE TUBULAR MEMBER PACKER ARRANGEMENT AND METHOD Abstract of the Disclosure A retrievable packer arrangement that can be used as a permanent production packer employs a simple compression set packer (P) which can be either mechanically, hydraulically or wireline explosively set and retrieved by coupled or coiled pipe or wireline. The arrangement includes an adapter (A) supported by the setting tool (ST) which surrounds an external seal surface (19) on the upper end of an inner tubular member (I) which seal surface is exposed after the packer arrangement isset in a well bore tubular member (T) by release of the setting tool (ST) from the inner member (I) and removal of the adapter (A) therewith, so that a production string (PS) may then sealingly telescope over the inner member upper end. An outer member (O) includes release means adjacent its upper external end including an external grapple engaging surface means (100) so that the packer arrangement can be released without engaging the packer (P) or slips (76,76') which secure the packer arrangement in the tubular member (T) and with- out inserting any mechanism in the set packer arrangement. The packer arrangement provides an unrestricted bore for well tools and flow from the well. The invention also contemplates lowering a landing nipple (LN) into a well bore tubular member to a desired location and sealably anchoring it at thatlocation by a retrievable packer (P'), for subsequent removal by a grapple tool supported on pipe or a wireline.
