Tubing Casing Patch Technologies

The Owen X-SPAN® Tubing/Casing patch System provides a proven, durable and dependable seal over perforations, splits, corrosions or leaks in all types of tubulars. This system can be deployed on electric wireline or tubing and used on conventional, horizontal, monobore, multi-lateral, slim hole or geothermal well bores. The Owen X-SPAN® System has proven to be an economical and reliable solution for a broad range of applications, including shutting off unwanted water influx, zonal protection for frac-through applications, repairing tubular leaks from pin holes to collar leaks, repairing corroded or eroded tubing or casing as well as isolating frac ports and auxiliary tools in horizontal wells.

The large bore assures easy passage of service tools including bridge plugs, drop balls, seal bore assemblies, logging tools and perforating systems. The minimal surface equipment required for deploying the patch and rig less intervention results in tremendous savings for the operator. The metal-to-metal X-SPAN® seal is proven technology engineered for high temperature applications while yielding the highest burst and collapse pressure ratings in the industry. The X-SPAN® casing patch can be deployed to protect 300-ft (91-m) sections of tubing or casing on a single trip, with multi-trip stackable patches available to span longer intervals. X-SPAN® Systems can be designed using premium alloys for extreme well bore environments and custom sized for most tubing restrictions.


The full range of Owen's X-SPAN® Technology include:

  • The standard X-SPAN® System consists of three basic components; a top metal to metal sealing element, a tubular extension and a bottom metal to metal sealing element. The system is modular and patch lengths can be adjusted at the field. It is the most reliable patch on the market and the pressure integrity is not reduced due to casing conditions.
  • The GTX-SPAN® adds premium sealing elements with each element containing two elastomer seals that have enabled us to provide the industry with the first effective gas tight patch.
  • The BPX-SPAN® is an elastomer free bridge plug designed for hostile well conditions that can cause the elastomers to swell on standard bridge plugs while running in the hole. The BPX-SPAN® uses our proven metal to metal seal technology to create a mechanical seal and anchor to the casing wall. The BPX-SPAN® can include a ceramic knock out sub, pump out sub or burst disc or be converted as a hanger system for velocity strings or include a tailpipe assembly with profile subs.
  • The new multi-trip stackable STX-SPAN® version can be utilized to isolate longer intervals and deployment can be performed on flowing or static wells. The STX-SPAN® System is also ideal for wells with limited rig up height and on wells that have severe dog legs where only short sections will pass. Each section seals to the previous one via a ratchet latch stinger and seal bore receptacle.
  • The SST-SPAN® is an elastomer free suspension or hanger tool that can be used to hang tubing or velocity strings from in a well. The SST-SPAN® uses our proven metal to metal seal technology to create a mechanical seal and anchor to the casing wall. The SST-SPAN® is well suited for hostile environments including high C02 and high temperature applications.

All Owen X-SPAN® Systems are easily deployed using a range of multi-stage explosive or hydraulic setting tools. The explosive setting tools can be initiated electrically, on e-line or slick line using a variety of compatible firing systems. For your conventional tubing or coil tubing deployment requirements, we have several sizes of hydraulically operated setting tools available. X-SPAN® Systems are easily removable by just milling off the sealing elements. The reliability and quality of the X-SPAN® System has been proven many times over the past several years with over 2900 installations completed with a success rate of 98% when setting depth has been achieved.
