The Oilenco UniLOT (Universal Lockout Tool) is designed to permanently lock a tubing-retrievable subsurface safety valve (TRSSSV) in the open position, ensuring that the flapper does not obstruct its operation.

The mechanical UniLOT secures the flow tube in a position that stops the flapper from closing after the control line pressure is released.When the Oilenco UniLOT is deployed, downward jarring deforms the walls of the flow tube, permanently preventing it from returning to its original position and ensuring that the bore of the TRSSSV remains unobstructed.
