Latest Oil and Gas News Russia

Welltec® has recently introduced a new range of services: subsea interventions performed through Riserless Light Weight Interventions (RLWI) techniques.

Through RLWI technology, Welltec® provides increased access to subsea wells at one third of the cost of a typical intervention. Oil companies are presented with improved monitoring of their reservoirs, access to more information and significantly improved operating efficiency. In addition, HSE benefits are champing at the bit, including lightweight technology, no heavy lifts, easy transportation, less people on board and the ability to perform operations from small vessels - in contrast to the large and costly moored, semi-submersible drilling rigs required by traditional methods.

Welltec® will offer a variety of electric wireline services for subsea wells including production logging, installation of plugs and packers to isolate specific zones, perforations, scale milling and sand removal.

World Record Water Depth for Subsea Riserless Light Well Intervention
In 2010, Welltec® was part of a team that completed a world record riserless subsea well intervention on 9/32" electric wireline in a gas producing well. The intervention was executed in 2,975 feet of water depth and another 12,000 feet measured depth downhole from a Dynamically Positioned type 2 multi service vessel in the Gulf of Mexico.

The Well Tractor®, Well Miller® and Well Key® were successfully deployed on electric wireline through the open water, subsea lubricator and into the well.

Case History - Riser Less Subsea Scale Milling in Three Hours
In the North Sea, Welltec® has completed a successful calcium carbonate scale milling operation at a record setting time. The job was executed on a subsea well from an intervention vessel as a RLWI.

The operator was experiencing reduced production and was not able to run a production log to total depth to locate the problem due to a large restriction at 17,034 ft MD. The Well Tractor® and Well Miller® configured with a novel 5.7" convex bit were mobilized and tagged the scale. Milling continued down to 17,052 ft until there was no indication at surface of milling in scale.

The intervention was performed extremely fast: in three hours of downhole operations, 18 ft of calcium carbonate scale was removed. Furthermore, the operation led to a significant increase in oil production.

Welltec® is the first company in the world to offer a solution for efficiently milling nipple profiles on electric wireline. This can be achieved by applying the Well Miller® NPR (Nipple Profile Removal) that offers a new bit design for the field proven Well Miller® system along with hydraulically provided weight on bit (WOB) by the Well Stroker®.

This innovative system offers operational efficiencies never seen before in conventional pipe-conveyed technologies, generating huge cost savings and value creation to operators worldwide. The main application for this solution is to increase the well internal diameter through nipple profiles to allow larger diameter intervention products to pass.

Avoid Killing Your Wells
This new system is the only one of its kind on the market. A major benefit of deploying the new milling system as opposed to the pipe-conveyed methods is avoiding the need for a well kill, which saves time and reduces possible formation damage. The milling system uses the well fluids to cool and lubricate the bit while cuttings are captured on magnets positioned above the bit. Since operations can be performed under live well conditions, the production can be returned quickly or further intervention operations can be performed on wireline.

HSE Benefits
The alternative to this system is far more costly and complicated. Using traditional methods involves a large footprint for pumping equipment and fluids handling and requires prolonged operating times, several heavy lifts, all of which results in complex logistics.

Field Experience
The world's first nipple profile removal on wireline was performed in Indonesia, where an operator needed to remove multiple nipple profiles in order to deploy a larger OD straddle packer assembly. In 10 separate wells with 2 Super 13 Chrome nipples in each, Welltec® successfully enlarged with the nipples with two different bits for the Well Miller® NPR. The entire operation was performed in 11 and a half days at total costs less than half compared to an operation performed with traditional methods.

The milling system has also been successfully applied to remove restrictions caused by partial liner collapse or kinks within the completion string. In the North Sea, the Well Miller® NPR has been deployed to mill a partial tubing collapse, hich was achieved in only 6 hours.

Welltec Well Completions visualize "Intelligent Design of Wells" whereby CAPEX is invested when (if) production dictates, life of well reliability is achieved through both simplicity in design and replaceability of hardware; and well flexibility is retained to enable side tracks, laterals and future planning for well abandonment.

Welltec's Well Completion Products (WCP) will deliver life of well reliability with on demand solutions that delivers well design flexibility to maximize production as the reservoir matures.

Well Annular Barrier (WA)
First WCP to market is the Well Annular Barrier (WAB), a hydraulic expandable metal annular barrier with a technical specification that far surpasses swell packer or external casing packer solutions on the market. The WAB maintains maximum well bore with expansion capability up to 1.4 times on running OD operated via surface control and has capacity to seal up to 10,000 psi delta P during injection and stimulation operations. The life and performance of the barrier is independent of downhole fluid type.

During 2009, Welltec® was awarded a contract for the qualification of the WAB for an ultra deep, deep water high pressure well. The WAB forms part of an integral single trip, frac and pack completion. It was selected for this high value well based on its many advantages compared to external casing packers or swell packer type solutions.

Further WAB developments are being implemented. In particular, solutions for wells that experience ultra high draw downs between zones and wells that have ultra high temperature requirements.

Future Developments
Apart from the WAB, Welltec® will be introducing additional Well Completion Products to the industry, including valves to deliver constant flow into the well and a patch thru patch solution.

Please introduce yourself with a short bio and your history in Russia
Since 2008 I have been based in Moscow, serving as Tenaris's Sales Director for the CIS region. I am a Mechanical Engineer.

How long have you been doing business in the region?
Tenaris has been present in Russia since 1992. We opened our office in Moscow in 2004. During 2008, we have doubled the size of our office, incorporating local staff to our Commercial team.

Do you have specific target markets in the region? (ie Russia, Kazakhstan, key regions or market sectors offshore, EOR etc?)
For the CIS region we have built a team of technical and field specialists to serve our customers throughout the region. Along with our office in Moscow, we also have a presence in Kazakhstan through our office in Almaty and our threading facility in Aktau.

We are a supplier of tubular technologies and related services to oil and gas companies such as Rosneft, Gazprom, Lukoil, KCO, KPO and TCO. Our technology benefits our customers' challenging operations including applications in both offshore and onshore extended reach wells, sour environments and Arctic temperatures.

We are working to complement service companies such as Weatherford to contribute to drilling with casing projects. Also, we are introducing our Blue™ Near Flush connection technology in the Caspian Sea region.

What are your key products for the region and their benefits?
We currently offer tubular technology solutions for unconventional operations, such as extended reach wells, offshore operations or extreme temperatures, which are becoming increasingly more common throughout the region.

Our Dopeless® technology, a dry coating, is a strong alternative for operators in the Russian tundra, where sand storms and dust can cause galling when dope is employed during running.

Our TenarisHydril Wedge Series 500™ and Blue™ Series connections were designed for demanding applications. They can handle the high-torque requirements of extended reach and deep wells. Combined with the Dopeless® option, we can provide significant cost, HSE and operational benefits to oil and gas companies drilling offshore.

We also offer a wide variety of steel grades for complex environments. Our Sour Service grades enjoy a proven track record in the CIS region, especially in Caspian Sea developments. Our High Collapse grades withstand high pressures exerted by the reservoir or by ground movements or saline stratus, subjecting pipes to extreme localized external pressure.

How do you compare and compete with existing Russian Technology?
With our offer of technologically advanced products and related services, we are looking to complement local providers' manufacturing capabilities.

We contribute to Russian development with proven technology, logistical and material selection expertise. Working alongside our customers, we deliver solutions for complex operating environments.

When a customer selects a solution from our TenarisHydril premium connections portfolio, our Field Services team trains the local running team or performs the running for the customer. Our purpose is to promote knowledge transfer and encourage innovation in oil and gas drilling techniques.

How do you see the market developing over the next 5 years in your industry sector?
For the next five years we expect that drilling activity will increase mainly in the oil segment as Russia is looking to develop new areas to sustain or increase oil production. Tax incentives for select strategic areas will boost this trend.

Fields like Vankor, Sakhalin and those located in the north Caspian region are located in more demanding environments, requiring more advanced tubular technology solutions.

Regarding gas, we expect the development of significant projects such as Shtokman or Bovanenkovo in the Yamal Peninsula. Like the oilfields, these environments are very complex and require unique technology and experience.

For Shtokman, we believe Tenaris can make an important contribution. We previously worked with StatoilHydro, a partner in Shtokman, for the Snohvit project in the North Sea. Shtokman shares many of the same characteristics: it is an offshore gas project in an Arctic environment. We believe our experience and products are well positioned to make a significant contribution to this project.

Do you have any new products being launched?
We will soon be extending the Dopeless® technology solution, already available on our TenarisHydril Blue™ Series, to other products in our premium connections portfolio. We see a strong potential for this technology in offshore, extended reach and other demanding wells.

Do you have any recent regional success stories?
We have provided our TenarisHydril Blue™ connections and Dopeless® technology for Rosneft's Vankor project. Tenaris also provided Gazprom with sour service tubes and TenarisHydril Blue™ connections for the Astrakhan, Orenburg and Kuban regions. We have also supplied sour service tubing for Naryanmarneftegaz, a key project for the alliance between ConocoPhillips and Lukoil. In the Caspian region, we have worked with KCO on the Kaashagan development and with KPO on the Karachaganak project. We also have an agreement with Chevron for the Tengiz development.
