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.

Tubing

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 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 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 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 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 is an elastomer free suspension or hanger tool that can be used to hang tubing or velocity strings 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.

3D animation by Industrial3D for Saltel Industries expandable steel technology. Introduction to Expandable Steel Patches from Saltel Industries website ( 'As optimizing the recovery of hydrocarbon reserves has grown in importance, and effective reservoir management has become increasingly complex, the need for shutting-off unwanted perforations in both production and injection wells has been growing, and requirements to restore casing condition to lengthen well life have become common. Restoring casing integrity, for both casing repair or perforation shut-off, means meeting the seemingly contradictory objectives of obtaining a high pressure resistant seal down hole, while at the same time not significantly reducing the casing diameter nor restricting access to the wellbore below. A wide number of very different solutions have been used, including cement squeezes, injection of gels, straddle packers, and various composite and steel patches, all with varying levels of success. Saltel Industries has developed, tested and trialed the use of a stainless steel Patch which is expanded down hole to create a high pressure inner lining inside the casing. Initially designed for perforation shut-off the technology is also suitable for repairing short lengths of damaged or corroded casing.'

- Saltel expandable steel patch (ses patch). Application: water shut off, remedial solutions, life of well expandable steel solutions.Committed to service quality. The patch is carried down the hole and put in place with the downhole expansion tool. The packer is inflated with hydraulic Pressure from the surface (hydraulic skid). The patch is then expanded against the casing wall. After contact is obtained, an overpressure is used to energize the elastomer seal against the casing wall.
