CRA-Tubulars | The Corrosion Resistant Alternative is a newly established engineering firm, backed by decades of excellence, innovation, and commercialization. The company operates in the energy sector and seeks to help operators solve the issue of well integrity, associated cost and subsequent loss of oil production.
The company is in the final stage of designing a titanium lined composite tubing (or ‘TCT’) that aims to disrupt the deployment of premium metallic tubulars in upstream oil and gas.
TCT is the first non-metallic alternative specifically tailored to the downhole market that is dominated by tubulars based on metallic variants. The product development has yielded several patents on the design, material usage, production process, and material chemistry. Patent research has shown that there are currently no patents that prevent TCT from entering to the market.
CRA-Tubulars is an initiative by Emile Burnaby Lautier and cooperates with Voith Composites Se & Co. KG.
Voith sets standards in the markets for energy, oil & gas, paper, raw materials, transport & automotive. Emile is a recognized authority on non-metallic tubulars.

Mission

CRA-Tubulars aims to be a leading provider of high-performance corrosion resistant OTCG space. We do this by making down hole tubing out of titanium. It is established that titanium is the superior tubing solution, it is also assumed it is financially impractical for down hole applications, until now. CRA makes titanium tubulars affordable! Cost price of TCT is around Duplex 22.

Goals

To be entrusted with the most critical information about downhole well-integrity by our customers
To be the prime candidate that oil companies will ask to solve their most challenging upstream operational problems
To develop and deploy fit for purpose tubulars that exceed performance requirements and expectations
To be an industry partner with operators and assist in difficult operational challenges
To leverage aerospace advancements, employ those learnings and elevate field operational envelopes
To be an example in Corporate Social Responsibility in the energy sector
To ease technical challenges in the execution of safe and affordable CCS projects.

Vision

The development of advanced non-metallic wellbore solutions requires long term commitment from a team that is trusted by its customers and suppliers.
Through long term and personal relationships with customers, technology partners, and suppliers, CRA-Tubulars will build the level of trust that is needed for the free flow of information between the stakeholders in our business.

Market Challenge

The annual cost of OCTG tubing in the oil and gas production industry is estimated to be $91 Billion. The premium alloy market equates to $3.4 Billion for corrosion-resistant tubing. That figure breaks down to $1.7 Billion for chrome 13 and another $1.7 Billion for duplex and inconel completions in capital expenditures related to corrosion. The premium alloy market is a costly line item to operators OPEX.
In 2015, the Society of Petroleum Engineers estimates that of the over 2 Million global O&G wells, 812,000 are affected by corrosion and 32% of these wells suffer from well integrity issues. This is the major focus of CRA-Tubulars , to bring a life of the well solution to these well integrity issues.
These direct costs and HSE risks could rise further in coming years, as new field discoveries are found in deeper reservoirs with higher temperatures and pressures and containing greater concentrations of corrosive medium.
It is widely recognized within the industry that effective management of corrosion will contribute towards achieving the following benefits: Statutory / Corporate compliance with Safety, Health and Environmental (HSE) policies reduction in leaks Increased availability reduction in unplanned maintenance well integrity breaches.
Reduction in shut-in well costs.
Assets in the upstream oil and gas environment needing protection from corrosion may include wells, risers, drilling rigs, offshore platforms, pipeline connectors, and more.

Worldwide 812,000 wells are affected by integrity issues. Approximately 9 % are permanently shut-in and 10% are temporarily shut-in. Globally there are approximately 2,000 active drilling rigs, considering that an average rig will drill a new well every 6-8 weeks, this breaks down into 14,000 newly drilled wells per annum. With 812,000 affected by corrosion and an average well depth of 9,000 ft, the total market consists of 6 million feet of pipe. One CRA-Tubular’s production facility can produce approx. 800,000 ft per year generating an annual turnover of 90 MM USD. One facility equates to a cure for 0.025% of the corrosion affected wells.

TCT Operational Advantages: Producer

Titanium Composite Tubing (or "TCT") is Truly a Superior Solution

OPEX is impacted by Corrosion

The global cost of corrosion is estimated to be US$2.5 trillion, which is equivalent to 3.4% of the global GDP in (2013) and continues to grow annually. 

Duplex or Nickel-alloys

  • Expensive delay of corrosion
  • No cure to the problem

Titanium Composite Tubing

  • Use of industry standard titanium makes TCT virtually free of corrosion

OPEX is impacted by Workovers

For any new oil and gas project, calculating costs is key. Operators must assess both up-front capital expenditure (capex) as well as expected ongoing operational expenditure (opex) over the life of the project and weigh these figures against expected returns to ultimately determine if the development is financially viable.

Duplex or Nickel-alloys

  • Every workover doubles the well cost
  • 3-5 year workover cycle

Titanium Composite Tubing

  • Workover only to replace accessories, TCT can be resued
  • 20 year workover cycle

OPEX is impacted by Chemical Inhibitor Programs

Corrosive wells traditionally require premium tubulars that put protective chrome protector coat on steel pipe, however, it only slows down the destructive nature of H2S and CO2. It is common to additionally require a chemical regime as well. This too only slows down the inevitable well failure due to corrosion

Duplex or Nickel-alloys

  • Expensive Solutions: high cost short lifecycle

Titanium Composite Tubing

  • priced below CR22 for one tubing. 20-year workover cycle results in 62% lower CAPEX over lifecycle

OPEX is impacted by Leadtime and cash flow delays

Corrosive wells require premium materials that are not typical kept in stock and famously have long lead times for delivery, add to the equation that raw materials (nickel) are in high demand in other industries and a well could sit idle for days and months. These delays directly impact production and profits.

Duplex or Nickel-alloys

  • Lead times for metallic corrosion resistant alloy is notoriously long (8 – 18 months)

Titanium Composite Tubing

  • Locally produced TCT has a lead time of 2 months combined with HWU installation, 92% reduction in cash flow delay

OPEX is impacted by Stress Corrosion Cracking

Specifically in CCS and C02 injection wells, completions are subject to a major temperature swings while in tension in wellbore. The added corrosive nature of these wells induce stress cracks in traditional steel tubulars and become the weak link in the completion.

Duplex or Nickel-alloys

  • High stresses from tubing weight and pressure frequently results in sour and chloride SCC failures

Titanium Composite Tubing

  • The highest resistance, at most extreme conditions, even when conditions change over time

HSE is impacted by Corrosion

The upstream oil and gas industry has one of the highest rates of severe injuries compared to other large employment industries, according to an E&E News analysis of workplace injury data. By some measures, it has the highest.

Duplex or Nickel-alloys

  • Workovers are potential HSE hazards
  • H2S accidents kill people

Titanium Composite Tubing

  • Reduced HSE exposure

TCT is composed of a corrosion-resistant liner made of Titanium ASTM Grade-2. The liner is then covered with several layers of Aerospace grade carbon fiber and high-grade epoxy resin. The Ti. liner gives corrosion resistance and prevents permeation of any hydrocarbons into the CF layer. The CF layer provides strength in the axial and radial direction.

TCT is economical from a lifecycle cost perspective. It outlasts any high alloy metallic tubing. Considering the cost of several workovers, new tubing, chemical treatment, and cashflow impact resulting from shut-in periods, the price is very competitive. TCT is more economical than 13Cr tubing and certainly a lot less expensive than Duplex or Inconel tubing. TCT is priced slightly above CR13 tubing but will last many times longer.

CRA-Tubulars plans to manufacture tubing in-country or certainly within the region. In this model we expect to deliver a spool of TCT in under 1 month, combined with HWOU installation, our process can have your well back on production within 2 months. This is much faster than traditional jointed metal CRA completions. Delivery times of Duplex or Inconel are typically over 18 months.

TCT is slightly stronger in axial forces than metallic tubing is. Our prototype testing showed 240,000 lbs. before the tubing broke. Since it weighs only one-third of metal equivalent tubing, it is a much stronger downhole. Example: 10,000 feet of steel tubing weighs 92KLBS, and our tubing weighs only 30KLBS, so we would have ±62KLBS (92-30kLBS) more pulling force than metal tubing.

TCT is provided in two grades: Burst and collapse 10KSI and the high grade >15KSI. Temperature is 180 degrees Celsius; this puts our non-metallic CRA comfortably in the HPHT range of applications. We have a high grade under development aiming to approach 200C.

No, to achieve the highest possible temperature resistance we are using highly crosslinked thus brittle resins. Our combination of resin, fiber, and the liner however is not brittle. Microcracks do occur in the outer layer (none in the inner-liner) as soon as the pipe is spooled on a reel this is normal and does not affect its performance in any way.

Since TCT is as strong as metal, the behavior is expected to be similar. During such conditions steel tubing, drill pipe, and collars have been seen expelled from the well. That will likely happen with TCT too. Will it happen sooner? Not sure, but even if the event fully escalates 50% faster than with metal, the consequences will not be different, only instead of say an hour, it might happen in 30 minutes. Nothing to avert the consequence of such an event can be done in that time frame. Steel pipe, casing, and tubing have been sand-cut in minutes resulting from the extreme velocities of the two mediums together. Similar expectations for TCT.

There is no reason, when looking at other Industries, to believe non-metallic composite is less strong than metallic are. Airplanes are made of carbon fiber (CF), F1 cars are accident impact strengthened with CF. They are all much stronger than metal equivalent material. The unique and extreme forces in an uncontrolled well flow cannot be counteracted by metal or non-metallic composites, they will perform similarly.

Yes, there is sufficient safety on the collapse performance (radial hoop strength) to allow for safe installation and operation. Calculations have shown that with a tubing full of gas, zero pressure at surface, an annulus with packer fluid and max design pressure at surface (ie MDASP) there is no risk of collapse. Category: General Properties and Dimensions

In most of the corrosive well-operating environments, the expected life exceeds 20 to 30 years. Titanium is very durable, corrosion-resistant, and in other industries like seawater coolers in nuclear power plants and chemical industries, it is the metal of choice for high corrosion resistance.

Carbon fiber is strong and nearly inert to corrosion bar wet/temperature degradation over time. CRA-tubulars apply a safety factor to the operating envelope. The (initial) operating limits are the limits CF would have after degradation.

We use a propriety cross-over design from carbon-fiber composite to any metal CRA alloy matching any type of premium or non-premium thread required by the client.

As mentioned, we can provide any available thread type. TCT can be connected to any off-the-shelf completion accessory.

Our product is a reeled endless tubing and is delivered in this configuration. The maximum length depends on the number of completion accessories installed. It can be one length from hanger to the packer, or it can be in segments for instance, from hanger to SCSSV and then next to the packer.

Tubing stress analysis indicates that well depths over 6,000 meters are still well within the operating envelope of the tubing.

Intervention Activities

TCT will in general be used in wells requiring a metal CRA tubing completion. However, the corrosive film on the Titanium liner is much harder than metal CRA alloy. Therefore, it will be much more difficult to damage that film contrary to Duplex or Inconel alloys. However, it is recommended to design and execute interventions similar to high Chrome, Nickel, or Inconel tubing. Carbon steel intervention tools can chip off steel splinters which could be embedded in the metal CRA tubing and give access to corrosion. If it is necessary to perform Interventions, non-metallic centralizers should be deployed, reduced running speed, especially in dry completions, like gas-wells. Intervention tools shall be selected new, burrs filed off. Plastic coated wire is a distinct advantage in both types of CRA tubing.

Not all cutting tools are advisable. Obviously, chemical cutters will not work, similarly, they do not work on metallic CRA tubing. The electric pipe cutting tool from Sondex wireline has been successfully tested on these materials.

Yes, it can be milled but requires modified tools and reduced milling rates/conditions, bit type rpm, etc. The cuttings from milling the tubing are very light, and even lightweight, low viscosity brine will carry it to the surface.

In the case of severed tubing, the fishing operation is similar to metal tubing. The TOF can be dressed, fished internally, or externally. A grapple overshot with slips engaging on the outside of the tubing and possibly a spear inside could work equally well as with traditional metal tubing fishing.

In the unlikely event that after a bit and scraper run the well is not fully accessible, the impact of TCT tubing weighing one-third of its metal competitor is low. Furthermore, TCT is as strong as metal, no issues.

Yes, TCT tubing can be made-up to any standard, any manufacturer’s accessory, as well as to nipples for plugs, standing valves, beam-pump seating nipples, etc. Any conventional completion design can incorporate TCT tubing.

At the moment this has not been tested, however, looking at a large number of available alternative options, mechanical or explosive, it should be possible.

Yes, a hydraulic control-line can be incorporated into the outer layer. Using available SCSSV’s and packer with integrated control-line options, it can be supplied. Similarly, fiber optic cable can be integrated. Existing technology allows for the cable to exit the tubing, bypass the accessory, and connect to the optic cable below again.

Power cable for ESP can be “wrapped” in the out layer, providing a sturdy and protected alternative to traditionally banding to the outside of the tubing.

Yes, there is sufficient safety on the collapse performance (radial hoop strength) to allow for safe installation and operation. Calculations have shown that with a tubing full of gas, zero pressure at surface, an annulus with packer fluid and max design pressure at surface (ie MDASP) there is no risk of collapse. Category: General Properties and Dimensions

In conventional metal CRA completion, monitoring of corrosion during the production life of the well is desired.

Can we inspect, and is that needed, in non-metallic CRA tubing?

Pulsed Eddy is a technology that could be tried on this new development. It makes non-magnetic elements slightly magnetic showing wall thickness reduction. It is a proven technology in measuring riser wall thickness and airplane structure inspection.

Downhole Video is a visual option to investigate the condition of the inside of the tubing.

CRA tubulars intends to further develop this requirement for those clients needing to comply with this requirement.

CCS-Carbon Capture and Storage

Carbon Capture and Storage requires captured CO2 to be pumped as a liquid down old oil and gas wells. Pumping the liquid CO2 into an empty reservoir below hydrostatic pressures a well would allow the liquid to “evaporate” at the top of the well, resulting in a large temperature drop. This Joule Thompson cooling effect varies with the effective remaining reservoir pressure. Over time this evaporation will reduce as reservoir
pressure increases. TCT is designed with two unique components suited for this purpose, Titanium-Ti and Carbon Fiber-CF. Titanium has a track record as a storage vessel for liquid Helium and CF was used on NASA’s Space Shuttle liquid Oxygen and Hydrogen tanks. These proven track records in extreme cold environments, exhibit fit for purpose application of  TCT components. Kobe steel puts the minimum temperature limit of Titanium at minus -269 degrees Celsius (4 degrees Kelvin). Carbon fiber in the grade used in TCT can safely be applied to minus -40 degrees Celsius without losing its strength.
In comparison, (metallic-CRA-alloys) like Duplex or Super Duplex are limited at around minus -50 C and minus -100 degrees C respectively.
Additionally, prices of these (metallic-CRA-alloys) are much higher than TCT, making it a very interesting economical alternative in these applications.

The thermal resistance of carbon fiber (through-thickness) =0.8W/m-K.

The TCT total thermal resistance per length (1 meter) R=0.0339K/W

Carbon fiber has a negative Coefficient of Thermal Expansion (CTE) and since it is so much stiffer than the surrounding epoxy, the combined effect is dominated by the CF. Therefore, the Temperature Coefficient is between 1/3 and 1/2 of that of metal tubing.

This number will be derived from that of Titanium and carbon fiber and gives a thermal pipe resistance of R=0.0339K/W per unit length of 1 meter.

Titanium on its own is used for Helium storage vessels because of its extreme low-temperature capabilities. Carbon fiber on its own was used on the Space Shuttle liquid Oxygen and Hydrogen tanks. Both applications are low-temperature environments. The difference in the operating envelope in CCS wells and the aforementioned applications are the forces and stresses experienced in wells. However, Titanium shows an increase in tensile strength when cooled down (Source Kobe Steel).

Low Temperature Characteristics
Neither commercially pure titanium nor titanium alloys become brittle even at extremely low temperatures. In particular, commercially pure titanium and Ti-5AI-2.5Sn ELI can be used even at 4.2 K (-269°C)
(Fig. 4)

Carbon fiber has a negative Coefficient of Temperature Expansion (CTE), reducing thermal effects and forces resulting from temperature fluctuations. Our resin used in TCT can safely be exposed to minus -40 degrees Celsius. As can be seen from this temperature profile simulation illustrated, it would make TCT perfectly suitable for the large majority of CCS wells. It will only go below minus -20C in exceptional cases. At a price around 13Cr tubing, the Operator will get superior service to duplex or Inconel properties, low-temperature coefficient, and low tubing weight.

Rig and Other Means of Deployment

TCT will in general be used in wells requiring a metal CRA tubing completion. However, the corrosive film on the Titanium liner is much harder than metal CRA alloy. Therefore, it will be much more difficult to damage that film contrary to Duplex or Inconel alloys. However, it is recommended to design and execute interventions similar to high Chrome, Nickel, or Inconel tubing.
