| abstract | ABSTRACT OF THE DISCLOSURE A running tool for installing a wireline retrievable safety valve in a landing nipple of a well tubing string including a body connectible with a wireline tool string, a locking assembly for releasably locking the body with a well safety valve, a core connected with the body and connectible by a shear pin with a well safety valve, and spring isolator tube assembly connected with the core and engageable with a spring operator tube in a safety valve to hold the valve spring compressed during valve installations. The isolator tube assembly prevents down forces on the running tool from direct delivery to the spring operator tube during valve installation. |
