The Rebco ROTN Non-Selective Test Tool is a single-trip, seat-and-seal pressure barrier that lands on the bottom No-Go shoulder of any compatible bottom No-Go Landing Nipple to hold applied pressure from above, allowing the tubing string above the tool to be pressure tested from surface, leak-located, or used to set a hydraulic-set packer. Like the ROTFB-2 and ROTRB-2, the ROTN is not locked in the nipple profile; it rests and seals on the nipple's No-Go shoulder under its own weight and the applied test pressure, and incorporates a built-in equalizing feature to equalize pressure before retrieval.

The ROTN's "non-selective" designation means it cannot land on a specific nipple among several of the same size in a tubing string; it will seat in the first compatible bottom No-Go nipple it encounters while being run in. For this reason, the ROTN is most effective when there is a single target nipple or when the bottommost nipple in the string is the intended test point. The ROTN is a versatile tool compatible with a variety of Landing Nipple types that share a bottom No-Go design and compatible packing bore, making it a flexible choice when only a single test depth is required, and selective positioning is not needed.

Available in nominal sizes 2" through 5½", covering seal bore sizes from 1.781" to 4.562", the broadest size range of any test tool in Section VIII. Run and retrieve using the SB Pulling Tool or JDC Pulling Tool, selected by nominal size. All assemblies are manufactured from NACE MR-01-75 compliant normal alloy.

How to Order: Product Code 14. Specify nominal size, seal bore size, and material. Confirm that the bottom No-Go nipple type is present in the completion and that the packing bore is compatible with the ROTN. Non-standard sizes and materials available on request.
