FKAB L2, a perfect design for regional distribution of LNG
The FKAB L2 is a 16 500 m3 LNG vessel design primarily for regional distribution of LNG. In combination with the FKAB L1 design, presented in June 2009, the FKAB L2 design are FKAB contribution to the development of an efficient and sustainable sea based regional and local distribution system for LNG.
In 2006 FKAB identified natural gas in liquefied form (LNG) as an interesting and realistic alternative to conventional fuels on ships. Since then FKAB has closely monitored the development and spent significant resources in the development of various designs using LNG as fuel as well as designs used in the supply chain of LNG for ships.
The FKAB L2-design is tailor made for regional distribution of Liquefied Natural Gas (LNG). The LNG is stored in three insulated cargo tanks of bilobe type, classified by IMO as "Independent Type C". They have spherical heads and a design pressure of 4,1 barg. Each tank is equipped by two submerged deep well pumps for easy discharging. The discharge capacity is 6 x 300 m3/h.
The FKAB L2 main fuel is boil-off gas and regasified LNG from the cargo tanks. This will reduce fuel cost when operating the vessel. Despite this the L2 is designed to be as energy efficient as possible with amongst other a slender hull and a heat recovery system. These measures reduce costs further but will also reduce the environmental footprint of the vessel. To maintain flexibility and for emergency use the machinery is of dual fuel type and the vessel has capacity to carry MGO as fuel also.

Welltec company overview
Welltec is a rapidly growing international oil and gas services company delivering premium quality solutions. Our services address strategic and financially important challenges encountered by oil and gas companies. We have built a premier track record for reliable, high-quality service delivery. We thrive on innovative ideas and develop cutting-edge technologies that will continue to revolutionize oil and gas production.
We provide high-technology services in onshore and offshore wells, including in the most extreme operating conditions (such as deepwater, subsea, extended reach, Arctic, high-yield, heavy oil and unconventional gas environments). We have built a versatile company with multiple services across the different phases of a well's life including evaluation, drilling & completion, production and intervention.
We provide services primarily by operating proprietary remote-controlled precision robotic equipment designed and manufactured in-house. Our innovative technologies couple unique, patented designs with manufacturing know-how in, among other areas: electric, hydraulic and electronic systems. Our revolutionary services and technologies are broadly accepted by the industry and have changed the way operators manage their wells and reservoirs.
The industry has recognized Welltec's innovative technologies with several awards. We have won the prestigious Woelfel Best Mechanical Engineering Innovation Award and the Special Meritorious Award for Engineering Innovation several times. Our track record for continuous technological innovation includes awards for the Well Tractor in 1998, the Well Stroker in 2003 and, the Well Miller in 2007, no less than two awards for the Well Miller RCB (Reverse Circulating Bit) in 2008 and in 2009, the Well Cleaner PST (Power Suction Tool) took home the latest award.
How long have you been doing business in the region?
We have been doing business in the CIS since 1998. We did our first jobs in Russia at the beginning of 2009 and have now established ourselves in several regions of the country.
Do you have specific target markets in the region? (i.e. Russia, Kazakhstan, key regions or market sectors offshore, EOR etc?)
We have focused on Russia mainly in 2009 but in 2010, our focus will expand to include more Caspian countries, in particular Kazakhstan. We will work in whatever market brings value to our clients; however, the obvious target is the horizontal wells market.
What are your key products for the region and their benefits?
Our key services are provided with the Well Tractor, Well Miller, Well Cleaner and the Well Stroker. The entire concept of Welltec is to provide a lighter alternative to heavier forms of intervention, such as snubbing and rig units and in particular coiled tubing (CT). Being able to provide our alternative solutions on an electric wireline, as opposed to CT for example, brings obvious benefits. Less logistics issues, less people on the wellsite, no heavy lifts (everything can go on a chopper for example), faster rig up, rig down and operational running speeds, provide obvious HSE benefits. The bottom line is that we offer our clients faster, safer, more cost-effective interventions and thus reduced risk and costs of production.
What potential is there for your products in the market?
The potential for our services in the region is huge. For example, many areas either cannot source CT, or afford it, or perhaps logistically cannot get CT to the wellsite. We provide lighter, safer, more cost-effective and faster alternatives to heavier forms of intervention. That offer can bring real benefits to our clients.
How do you compare and compete with existing Russian Technology?
Our job is not to compete with, but to enhance existing technologies. We are working together with Russian geophysicists on most of our jobs and we appreciate their technologies and they appreciate ours. We work together hand in hand with great results.
How do you see the market developing over the next 5 years in your industry sector?
We see it continuing to expand as we have only exploited a small area of the potential market. For example 2009, was a very difficult year for the service sector of our industry, but even during this depressed year Welltec continued to grow globally as we have every year since we came into existence in 1996.
Do you have any new products being launched?
Yes. We launch several new technologies every year to enhance our portfolio and in response to client requests. We will normally do formal launches of these technologies so watch this site for the next launch.
Do you have any recent regional success stories?
In February 2009, we conducted the first perforating on Well Tractor in Russia. The job was offshore Sakhalin Island. Although this is a standard operation, getting the first Russian job completed safely and successfully was a real achievement.
Any further comments?
We now have offices or operations in Vankor, Sakhalin, Tyumen, Krasnoyarsk and Moscow in Russia as well as in Baku, Azerbaijan. We have aggressive expansion plans in the Caspian region in particular in 2010 and have several new projects in Russia starting up during the year also. We plan to establish ourselves further in the region and stay a very long time.

ROGTEC Talks Exploration with Jean-Louis Gelot, Vice President, CGG Veritas Russia
1.a What are the key future and current exploration areas in Russia?
In Russia, although there is still room to find significant reserves in the southern part of western Siberia, exploration is definitely moving north an East. North of the mature Timan Pechora basin in the Pechora and Barents Sea, north of Western Siberia in Yamal-Nenets region and in Karal Sea, and then East in Eastern Siberia and Far East in the Sea of Okhotsk. Licensing will also take place in Laptev and East Siberian Seas. This is a huge exploration territory in harsh climatic and geographical areas
1.b What are the key future and current exploration areas in the Caspian?
In the Caspian Sea, the majority of issues related to sovereign claims between the littoral states have either been ratified or are close to agreement, i.e. Azerbaijan, Kazakhstan, Russia, Turkmenistan and Iran. Additional transportation infrastructure (BCT pipeline, expansion of the CPC, Trans Caspian link etc) will resolve the critical export issues for additional to-be-discovered hydrocarbon reserves. There will also be continued development of the onshore resources in these countries, where the potential investors profile are more in line with the reduced capital commitments and need for local partnerships that characterizes the onshore exploration market.
2 What are the key differences between exploring Russia and the Caspian?
Talking about seismic exploration, the main challenges in Russia are the very short acquisition survey time windows; December until April onshore in a large part of territory and July to October offshore. For large projects this means high capacity vessels (10 streamers) and a high productivity land crew which is possible with vibro-seismic in Yamal-Nenets region. This means technology, large equipment investment and know-how which do not exist today in Russia. If large seismic vessels can mobilize and demobilize quickly to other areas of the world, this is not the case with land crews. High productivity land crews, with long mob-demob periods, have very high depreciation costs with 8 months in stand-by. In the Caspian Sea, seismic exploration has its own difficulties with ice in winter and water depth changing significantly with wind.
3 What are the key regulatory issues faced in the region?
It is almost impossible for an international seismic contractor to work in Russia without a local partner. Permitting and authorisations with local regulatory agencies are very cumbersome. Access to restricted coordinates is denied to foreign companies although GPS technology is available anywhere in Russia! This means, for example, that a foreign geophysicist can not be involved in part of the field acquisition quality control. CGGVeritas has a strategy of partnership with Russian companies that will overcome these hurdles.
4 Up to 15% of the total global reserves are believed to lie undiscovered in the arctic. What measures are companies taking in order to take advantage of these reserves?
The Russian Ministry of Natural Resources is financing exploration programs. Russian giants GAZPROM and ROSNEFT, and IOC's have already made significant progress in the artic region. SHELL and EXXON are operators in Sakhalin projects. BP has a very large exploration project with ROSNEFT in the Far East. Shtokman will be developed with foreign IOC's and services companies. Rules for international operators about access to strategic deposits start to be more clear and this will accelerate new investments. Although this is not GOM or Brazil deep offshore, harsh climatic conditions increase CAPEX and OPEX. Better well productivity and reservoir management will be possible with intensive use of 3D seismic for development and production monitoring.
5 Siberia is a notoriously challenging area for both exploration and production of oil and gas. What are the major challenges faced when exploring the region?
As stated before, the main challenge is the short winter time window. Global warming certainly does not help! In East Siberia structural and stratigraphical complexity brings acquisition design and processing challenges. Some progressive E&P companies are evaluating onshore summer acquisition but this poses critical environmental issues. Low impact seismic, which is not well introduced in Russia, will help to move towards longer acquisition periods.
6.a What technologies are being implemented in order to overcome the harsh environmental conditions?
Offshore, CGGVeritas high capacity vessel fleet can satisfy demand for large (2000km2) surveys in summer. Solid streamer technology from our SERCEL equipment division is less sensitive to rough sea conditions, thus decreasing weather stand-by. Onshore, CGGVeritas has been using narrow drilling equipment and heliportable operations for a lesser environmental impact and can bring this know how to Russia. HPVA (high productivity Vibroseis Acquisition) with high channel count ( SERCEL 428) used in Middle Eastern desert areas can be deployed in Northern West Siberia.
6.b What advances can you see happening in the future that will aid the exploration of remote and hard to reach areas?
Again, onshore, the next step will be the use of helicopters during summer. Russian companies do not have this experience. We, at CGGVeritas, have a strong reputation in this area.
7 To what extent will your exploration and production technologies and working practices be modified to address the environmental sensitivity of the Arctic?
CGGVeritas has very strict HSE rules. For example, with the AGC (Association of Geophysical contractors), we are proactive in evaluating the impact of offshore seismic on mammals. Solid streamer technology overcomes the potential contamination issues that existed with fluid filled streamers
8 Russia's output has declined slightly over the last decade due to underinvestment in exploration during the Soviet era, creating a drive to push exploration boundaries further in to Siberia and the Artic shelf. How do you see the attitudes to exploration in Russia changing?
Russia has realised again recently that exploration is very much needed. The Ministry of Natural resources (MNR) is financing large 2D seismic programs in artic waters as well as in East Siberia. It is also revising licensing terms for exploration (geological licenses) where the license owner will be able to transform the license into an exploitation license in case of deposit discovery. The MNR is also clarifying the rules for foreign operators with the definition of strategic fields. New ongoing construction of oil and gas pipelines towards the Pacific coast and China will contribute in accelerateing the exploration and development of East Siberia.
9 Many of Russia's more mature fields are on a downward production curve. What role do the latest exploration methods have in increasing the outputs of these depleting fields?
More than exploration methods, we would talk about seismic technology for better reservoir characterisation and therefore optimized well placement and productivity. For fractured reservoirs, wide azimuth, longer offset and multicomponent acquisition, azimutal anisotropy dependent processing and seismic fracture characterization are key technologies not yet widely used in Russia. In clastic reservoirs, I would use the same comments about better acquisition design coupled with full elastic and petrophysical inversion techniques.
10.a How are Western companies working with Russian companies to enhance technology in this area?
CGGVeritas has an open technology business model. Russian seismic contractors intensively use our latest SERCEL seismic equipment (SERCEL 428) as well as our GEOCLUSTER software technology that they can buy on a commercial basis. Russian contractors also benefit from our partnership strategy.
10.b What key partnerships have you undertaken to enhance your technology transfer and under taking?
Our key partnerships with Russian contractors are still in their early days. For the last 3 years, CGG Group resources have been committed to our more traditional markets. However, with our recent merger, CGGVeritas is in a better position to develop these Russian partnerships. It is a large market with many local players, and hence it will take time.
11 What are the key processes that you undertake in order to maximize the quality of the data that you produce?
In our partnerships, we have introduced our CGGVeritas integrated standard quality control process during field acquisition. We would also like to see higher geophysical expertise in Russian E&P companies so that their standards, in terms of quality and productivity, can rise to international levels.
12 What advances have been made within data processing and interpreting these results?
CGGVeritas offers the most complete set of processing algorithms available on the market. The best of both CGG and VERITAS is now being gathered into a full single offer. Listing all algorithms and methodology would go beyond this interview. VERITAS brings its current Canadian artic experience, such as dealing with permafrost, to the similar conditions of Russia.
Jean Luis Gelot is CGGVeritas country manager, based in Moscow, in charge of business development for Russia. After 10 years in mining and underground water geophysics in various countries, he managed a geosciences software company (GEOMATH Inc.) from 1990 till 1998 in Denver and Houston. In 1998 he joined CGG Americas as manager of integrated reservoir studies services with postings in Rio de Janeiro, Houston and Caracas. He moved to Moscow in early 2005.
He holds a MS in Mechanical Engineering (Arts et Metiers-France) and Petroleum Geophysics (Institut Francais du Petrole). He is a member of AAPG, SEG, EAGE and SPE.
