<p>A method for selectively communicating with a hydraulic nipple within a wellbore comprises positioning the hydraulic nipple within the wellbore. The hydraulic nipple comprises a first and second communications component in communication with a first control line extending from the surface. A first fluid is communicated through the first control line and into the second communications component, wherein the hydraulic nipple is positioned below a tubing retrievable surface controlled subsurface safety valve ("TRSCSSV"), the TRSCSSV having a second control line extending from the surface, the second control line being separate from the first control line. A method for selectively communicating with a tool landed inside a hydraulic nipple is also provided. This method comprises positioning the hydraulic nipple beneath the TRSCSSV, the TRSCSSV communicating with a first control line extending from the surface and the hydraulic nipple communicating with a second control line extending from the surface, the second control line being separate from the first control line; and selectively communicating with the tool via the second control line.</p> |
