OTW-12 - Superior performance for new part protection and worn coating repairs Down Hole Wear issues The world demand for energy is escalating. Two of the few major energy sources are Oil & Gas. In order to extract these energy resources drilling must be used to reach the underground reservoirs. Major oilfields are found on both land (onshore) and under the sea bed (offshore). When drilling for Oil & Gas, a drill bit is used attached to a drill pipe tools with diameters from 1000 mm down to 100mm. The largest hole is at the top of the well which

must be sealed as the steps get deeper. This is called well construction. The well is sealed from collapsing by using a steel tube with cement to fix it to the well formation. This steel tube is called the casing which has several functions. The major one is to seal off the well from its high pressure. In “open hole” drilling the tools are exposed to the severe wear from the formation, after setting the casing. The current depths of wells are from 3,000 m to 10,000 m deep.

What is Hardbanding? Hardbanding is a very established name for the wearfacing welding process used in drilling to minimize wear on casing and drilling tool joints in order to reduce operational costs associated with Oil & Gas production. It involves the application of a wearfacing material on the drill tool joint. The process is done by approved hardbanding applicators for OEM drill pipe producers and drilling companies. Trio OilTec Services have executed hardbanding in the Norwegian market for more than 8 years. Due to excellent co-operation between Trio OilTec Services and StatoilHydro, there has been a very success-

ful development and use of new, innovative alloys such as OTW-12, OTW-16 wires and also special coating (MX5). Today Statoil- Hydro approves OTW-12, OTW-16 and the MX5 coating for drilling. In the development of these products, TRIO, took this task very seriously, and uniquely in the industry constructed its own dedicated hardbanding Wear test Machine and also full scale automated Hardbanding welding system. With Trio’s integration into the global Castolin Eutectic organisation, there is an extension its product offer outside of Norway.

Schematic of wear sources

A special Oil and Gas application Why use “OTW-12 Wearfacing technology” ? “Hardfacing” is commonly used by engineers to describe protecting metal parts against wear to extend their service life using “hard alloy” surface coatings. In fact, practical industrial experiences have demonstrated that lower hardness alloys but with intrinsic toughness or frictional properties, can often lead to more optimal solutions. For this reason, Castolin Eutectic prefers the term “Wearfacing” which better reflects the importance to select the surface coating alloy in function of its properties to resist the specific wear mechanisms present rather than a simplistic hardness value. Understanding this difference is critical in the Hardbanding business, and means understanding that actually 3 properties are required: High wear resistance of the Tool Low wear of the casing from the tool hardbanding Low coefficient of friction of hard banding Castolin Eutectic and Trio constructed the only Hardbanding test machine owned by a consumable developer in the world and set about developing a range of alloy solutions, all manufactured in house. The machine measures all 3 properties for a range of typical muds.

Benchmarking was also made against the most commonly used weld overlay wires in the industry. The R&D work, together with StateOil company funded research over many years lead to the development of OTW-12. The success of any alloy is heavily dependent on the welding parameters and procedures that are used. These have been optimised in the group and also produced on the Hardbanding machines at Trio.

R&D with Oil experts Optimisation and Testing of weld parameters on Trio’s advanced Hardbanding machine 100 years of wear and welding expertise With Castolin Eutectic and Trio OilTec Services there is no outsourcing of R&D, nor Wire Production, nor Welding Expertise nor wear testing. Everything is in house and ISO certified. OTW-12 has been formulated to confer optimum hardbanding wear resistance in open hole drilling situations whilst retaining “casing friendly” properties. The wear resistant information is given below, but in addition, there are some other specific performance enhancing properties and features:

Dedicated Hardbanding wear test machine

A Competent Partner - control over quality at every stage. When you buy OTW-12, you not only buy a cost saving solution, but the knowledge that world class experts in the Castolin Eutectic organisation are involved at all stages: Internal R&D on dedicated hard banding machine Wire production in State of the Art Castolin Eutectic production facilities

Smooth weld deposit profile Crack free formulation Elimination of spalling risks Improved fatigue strength Multipass capabilities up to 15 mm thickness Easy rewelding over worn hard banding In conclusion, in addition to extending the service life of new and worn hardbanding parts, “OTW-12 Wearfacing technology” also ensures: Increased operating efficiency with less downtime Minimised maintenance costs Reduced stocks of spare parts Lower cost grade steel can be used Thus Castolin Eutectic’s “OTW-12 Wearfacing technology” is particularly cost effective for OEM Hardbanding of new drillpipe, tool joints & collars as well as reclaiming & restoring worn components back into service by drilling contractors & operators.

OTW-12 - Superior performance for new part protection & worn coating repairs

Low dilution of welded OTW-12

Description Proprietary, self or gas shielded, flux cored alloy wire specifically developed for Hardbanding of drilling pipe Tool-Joints. The high quality alloy deposit assures a smooth aswelded surface. Wear resistance performance in open hole situations is amongst the best in the market with lowest casing-wear properties. This alloy may be cost effectively reapplied over itself to refurbish worn drill pipes after oil well operations. It is only necessary to ensure that the base material and old OTW-12 coating are free of any physical defects and that safe dimension tolerances are retained.

The alloy is formulated to produce a unique microstructure with numerous, very fine, ultra-hard Ti phases in a relatively tough martensitic matrix, giving excellent overall resistance to combined wear by gouging abrasion, erosion, heavy impact and pressure at ambient temperatures.

Ideal choice for field work or on site applications. No need for costly gas cylinders, regulators or flow meters. Core de-oxidizers tolerate air currents or draught effects. Relatively thick, wide overlays possible in single pass.

Ideal for multi-pass coatings up to 5/8” (15mm) thickness. Deposits resist stress relief cracking and have very low dilution with base metal. Few slag residues save weld cleaning time. Easy striking and re-striking.

Lower heat input Reduced dilution Better bonding Shallow heat affected zone Minimal undercutting
