Abstract
There is disclosed a well packer assembly which comprises a packer which includes a body having a bore therethrough and a packing element and slips carried about the body in contracted position. The packer is lowered into a well bore by means of a locator seal unit which includes a tubular member connectable as part of a well tubing and extending sealably within the bore of the tubular member. The tubular member is automatically released from its connection to the packer in response to expansion of the packing element and slips into engagement with the well bore and testing of the set packer by means of test fluid in the annulus above it. The packing element and slips are expanded by inhibitor fluid from a source at surface level, and the inhibitor fluid is released into the annulus below the packer after it is set.
