Claims
- 1. A method of operably installing in a single trip a well safety system having a full opening remote controlled subsurface safety valve in the well, including the steps of:
- connecting a subsurface tubing hanger in a string of well tubing;
- connecting the full opening remote controlled subsurface safety valve in the well tubing above the subsurface tubing hanger;
- connecting a full-strength safety joint in the well tubing above the full opening remote controlled subsurface safety valve;
- connecting a predetermined amount of well tubing above the subsurface safety valve while moving the subsurface safety valve in the well;
- mounting a wellhead hanger above the predetermined amount of well tubing;
- positioning the wellhead hanger a predetermined distance above the wellhead;
- determining the weight supported by the wellhead hanger when positioned the predetermined distance above the wellhead;
- setting the subsurface tubing hanger in the well for supporting the string of well tubing below the subsurface tubing hanger;
- lowering the wellhead hanger into the wellhead;
- determining the weight supported by the wellhead hanger while lowering the wellhead hanger into the wellhead;
- comparing the weight supported determinations to develop a sufficient difference to indicate the subsurface tubing hanger is supporting the portion of the well tubing suspended therefrom;
- activating the safety joint to reduce the strength of the safety joint; and
- operating the subsurface safety valve to enable flow through the well tubing.
