Completion Equipment
20-215 RLOS Locator Seal Assembly

Product Overview

The RLOS locator seal assembly is a high performance device used as a sealing interface between the completion tubing string and seal bore packers such as the Resource Well Completion Technologies models RHSB, RHRB, RLB and RSB. The RLOS seal assembly locates into the top end of a seal bore packer by stabbing the seal unit into the packer bore and applying slight set down weight until the seals are fully engaged inside the packer bore. The RLOS seal assembly is released simply by picking up the tubing string to disengage the seals. The seal component of the RLOS seal assembly provides a positive, dynamic, high pressure high temperature seal interface between the packer and the tubing. Chevron style v-seal stacks are standard and are available in various materials and configurations to accommodate virtually all well conditions. Bonded seal units are also available in various materials upon request. As standard the RLOS body is manufactured from materials which conform to NACE MR-0175 for H2S service applications with a differential pressure rating of 7,500 psi. The RLOS is also available in alternate materials for severe environments and at differential pressure ratings up to 10,000 psi*.  A full line of accessory equipment is available such as spacer tubes, seal units, mule shoes, and production tubes.
