The FNR is the first API 19CI Qualified Retrievable Injection Valve to be installed in the North Sea. This case study outlines the challenges faced, the solution developed, and the resulting benefits of this ground-breaking technology.
TCO's recent breakthrough in subsea technology is the Disappearing Tubing Hanger Plug (DTHP) with fluid bypass sleeve. With remote opening and closing mechanisms and TR qualified control line clamps, this innovation has significant implications for safety and efficiency in subsea operations. This case study will explore its benefits.
Our client wanted to remove the displacement of Nitrogen process to increase safety and reduce time.
TCO was contacted by a major Norwegian operator with a request for a high differential pressure rated barrier plug. This plug needed to be installed in a 4 ½” lower completion and would need to be rated to 10,000 psi differential to ISO 14998 V0.
TCO APRS was installed in a subsea well during casing patch operations to eliminate casing collapse at production startup. The APRS was mobilized on a quick turnover which reduced the well suspension time
