  Why are the towers in the seas? What is a drilling platform? Types of drilling platforms. Types of offshore platforms

Rosneft, as part of the Sakhalin-1 Project Consortium, has successfully completed drilling the longest well in the world at the Chayvo field.

An O-14 production well has been drilled towards the extreme southeast end of the field from the Orlan drilling platform. The well has the world's largest borehole depth of 13,500 meters and a horizontal section of the barrel 12,033 meters long. It took 156 days to drill the well.

Let's go to the distant Sea of \u200b\u200bOkhotsk and see how oil is extracted from its bottom.

1. The journey to the drilling platform begins with the helipad of the Chayvo offshore product preparation complex. First, a thorough briefing, putting on rescue diving suits and updating the flight plan and filming. I’ll make a separate story about the flight itself, it was painfully different in it from the usual helicopter flight.

2. The shallow shelf of the Sea of \u200b\u200bOkhotsk. There is still ice on the shore, and a little in the distance it has already opened.

3. Potential recoverable reserves for the Sakhalin-1 project are 307 million tons (2.3 billion barrels) of oil and 485 billion cubic meters. meters (17.1 trillion cubic feet) of natural gas.

4. They are all located under the sea bottom of the Sea of \u200b\u200bOkhotsk in three fields: Chayvo, Odoptu, and Arkutun-Dagi.

5. On approaching the platform we are met by the support vessel Kigoriak, which is constantly on duty near the drilling platform according to safety rules.

6. We sat on the platform. Our luggage is unloaded and everyone leaves. Only photographers and cameramen remain in the helicopter. Now we will shoot beautiful views and panoramas.

7. Drilling platform "Orlan", support vessel "Kigoriak" and supply vessel "Vitus Bering". The steel base "Orlan" easily withstands the onslaught of ice and giant hummocks, reaching the height of a six-story building.

8. The Orlan platform was originally called the Glomar Beaufor sea I (Glomar Beaufort Sea I) and was built in 1983-1984. in Japan. In 1984, the platform was towed and installed in the Beaufort Sea (USA, Alaska). The platform was operated as an exploratory drilling rig. As a result of its operation, it was practically proved that the design of the platform is suitable for year-round operation in harsh Arctic conditions. In the period from 1984 to 1997, 6 exploratory wells were drilled by the platform. Further, the platform was purchased for the Sakhalin-1 project and converted from an exploratory to an extractive one.

9. After a global modernization, when the latest drilling equipment was mounted on the platform (and in fact, only the foundation remained from the old platform), the Orlan was towed to a permanent parking lot. Its pontoons were filled and the platform sank forever to the prepared bottom of the Sea of \u200b\u200bOkhotsk. At the Orlan platform installation site with drilling and residential modules, the sea depth is 15 m. This happened in 2004.

10. For the delivery of goods, temporary storage or placement of personnel (if the number of empty seats on the platform has run out), the latest vessel (launched in 2013) of the icebreaking class Vitus Bering is used. At the time of the survey, drill pipes were loaded onto the vessel after completion of drilling of the O-14 well.

11. Safety comes first. Both personal and industrial. They immediately warn that electronic devices (telephones, for example) can only be used in a residential unit. I’ll tell you about cameras later - not everything was simple there. For a shift conducted without incident, everyone receives a significant bonus. But if someone cuts at least a finger, that's all - there is no prize. Therefore, everyone looks after themselves and their neighbor so that all safety standards are respected. In the comments below they wrote to me that this is a duck. I don’t know, I just heard it on the platform. Most likely the truth is somewhere nearby.

12. Our acquaintance with the platform starts from the collection point for lifeboat No. 4. Our whole group is assigned to it. In case of alarm, you should arrive at this point, turn the card over and wait for directions here.

13. At the first three boats rescue diving suits are stored near the collection point - in the dining room. It is also a protected bunker shelter in case of emergency. And our wetsuits are stored near the boat itself.

14. All the dining rooms of the project are an example of cookery art. Of course, here you will not find fanciful dishes, but everything is very tasty and varied. In addition to the first and second, you can find salads, herbs, vegetables, fruits, desserts, pastries, ice cream (!), Juices, water. Everything is free and the number of approaches is unlimited. :)

15. A study in a residential module. All in all, nothing special.

16. Throughout the module, security corners are made. Rescue equipment, stretchers, first aid kits.

17. As far as I know, there is no camera in an explosion-proof enclosure. There are even special cameras in explosion-proof performance, but, as they say, they shoot poorly. And with the usual good camera in the working area is impossible. But how to shoot? Therefore, gas analyzers are hung on us. The instruction is simple - if it does, then you need to quickly leave this room and only then figure it out, and why did it clean.

18. Brief educational program - what is a borehole. The main idea is like a high-rise building, but vice versa. First they drill a large diameter, and then slowly reduce it.

19. Real drillers. Watch 28 days. Work 12/12 hours. Pay attention to helmets - they are all with wide brim. This is done in order to protect the shoulders of falling objects or liquids.

20. Our group. Fireproof coveralls, hard hats, glasses and white gloves! By the way, it turned out to be very comfortable. Naturally, special shoes.

21. I would like to say a separate word about the team. About 100 people work on the platform for a month. They are all professionals of the highest quality. But the platform is a small island in the sea. And the company is doing everything possible to maintain a healthy mood in the team during work. Good and tasty food in the dining room is one of the components, by the way. As well as lounges and a gym ... Well, people ... Everything, I want to emphasize that it is all with whom I spoke - examples of calm, cheerfulness and professionalism.

22. The pipe warehouse. In the photo there is a small part of it. As kilometers of pipes are extracted, they are stored here, and then loaded onto a supply vessel.

23. The best view on the platform!

24. Although, there are not many special species there. I looked around and that's it. Pay attention to the gray wall on the left. This is part of the drilling complex. Look at the bottom made a flexible supply of communications. The fact is that the platform is motionless, and it is necessary to drill a couple of dozen wells. Therefore, the drill moves along the X and Y coordinates. The range of mobility in any direction is about 10 meters.

25. At the time of helicopter landing, the crane was fixed, and the supply vessel moved away from the platform. Now loading operations have resumed.

26. And how lucky we are with the weather!

. :: clickable ::.

27. And now it's time to the rig. Just the other day, OJSC Rosneft Oil Company, as part of the Sakhalin-1 Project Consortium, successfully completed drilling the longest well in the world at the Chayvo field, the O-14 production well. This well was drilled in the direction of the extreme southeastern end of the field from the Orlan drilling platform. The well has the largest trunk length in the world, equal to 13,500 meters, and a deviation from the vertical of 12,034 meters.

28. The operator and his assistant. From here, all process control is carried out.

29. Everything is as automated as possible.

30. This is one of the most powerful offshore oil rigs in the world.

31. Captain of the drilling platform.

32. The achieved depth of the well along the bore (13,500 m) is actually close to the limit in technical capabilities for the currently existing drilling rigs and world technologies. At the time of shooting, the drill string was being extracted. As you can see in the photo, the drill is at a depth of 8887 meters.

33. Drilling operator.

34. It took 156 days to drill the well.

35. A minimum of facilities for the preparation of products is provided on the platform, since all extracted products are supplied to the Chayvo onshore training complex.

36. The record well is made according to the scheme of one trunk. But the platform already has multi-hole wells. This is when several trunks are drilled from one mouth.

37. After all 8.8 kilometers of pipes have been selected, a pipe for oil production will be lowered into the well and a new well will be put into operation.

38. Again we get to the site.

39. "Kigoriak" is the "North Star" from some language of the northern peoples. A contest for the best name was held and the boy won it. An excursion to the ship and a big cake were provided to him :) By the way, as they said on the platform, the entire bridge at the ship is filled with tubs with herbs and vegetables. So the captain has fun - grows his garden for a common table.

40. Loading of drill pipes.

41. Diamond drill bit. Differs in the highest accuracy and balancing.

42. Vincent Kessler - Project Manager. A real driller from Texas! He drove us along the platform and told us all the details.

43. The cabin control platform. All information from here is available online to everyone. Well, who has access, of course.

44. Scheme of drilled wells from the platform.

45. Preventer (from Lat. Praevenio - I warn you) - a working element of a blowout preventer kit installed at the wellhead. The main function of the preventer is to seal the mouth of an oil and gas well in emergency situations during construction or repair work at the well. Sealing the well prevents open flowing of oil and, as a result, prevents the occurrence of fire or environmental pollution.

46. \u200b\u200bFrom here, oil flows to the coastal complex.

47. Wellhead. O-14 is the twenty-first well. One more will be drilled and thus the total will be 22. There are no pumps in the wells. Oil rises only due to pressure in the reservoir. Naturally, associated gas is pumped back. Yes, there are 11 wells in the photo. The rest are under the floor, on the ground floor of the room.

48. Lifeboats.

49. 18 of the 30 longest BOW wells (a large departure from the vertical) in the world were drilled on the Sakhalin-1 project

50. In the following posts I will talk about the coastal complex and the Hawk drilling rig. A separate post will be about a specialized Mi-8 helicopter.

51. Many thanks to all the drilling workers for their hospitality and safety!

Special report of Vesti. Sorry, the code of their crooked player does not work.

The oil platform is a huge industrial complex designed for well drilling and production of hydrocarbon deposits lying at great depths. Installations for the extraction of oil and gas from the bowels of the Earth are amazing: imagine a man-made structure weighing half a million tons, capable of drilling wells up to 10-13 km even under partial immersion in water - and you will realize that this is a triumph of engineering thought of modern man. But even among these mighty structures, there are giants, one kind of which causes awe:

TROLL-A

The TROLL-A reinforced concrete fishing platform is the world's heaviest man-made facility, capable of moving across the surface of our planet. The total weight of the platform for natural gas production is 1.2 million tons with ballast loaded (dry weight - about 650-680,000 tons) and height - 472 meters (of which 369 are underwater concrete structure). This is a true marvel of engineering, installed at the Norwegian Troll oil and gas field in the North Sea.

Drilling rigs "Uralmash"


The largest surface drilling rigs from the 70s were produced in our country. The Uralmash-15000 BU was involved in the drilling of the Kola superdeep well: a structure the height of a 20-story building was able to drill a well up to 15 km deep! But the largest installations on floating platforms are considered Aker H-6e systems (pictured), also produced by the Norwegians. The area of \u200b\u200bthe working deck of this design is 6300 m 2, and the drilling depth reaches 10 km.

Statfjord-b


You can't get past the Statfjord-B rig, the largest floating technical facility in the world. The height of the tower, built in Norway in 1981, together with the concrete base is 271 meters, and the total weight of the structure is 840,000 tons. An industrial complex can produce up to 180,000 barrels of oil per day, while there will be enough tanks for 2,000,000 barrels. Moreover, the platform is a real city on the water: in addition to the rig, it houses a seven-story high-class hotel, chemical laboratory, helipad and a whole fleet of rescue and auxiliary equipment.

Perdido spar


But the deepest platform is located in the Gulf of Mexico, where it is moored at a depth of 2450 meters above the Perdido oil and gas field. Maximum platform productivity - 100,000 barrels of oil per day! The height of Perdido Spar is 267 meters, that is, it is a real underwater Eiffel Tower!

Eva-4000


Another giant, but of a new generation, is the Eva-4000 drilling platform, also located in the Gulf of Mexico, 240 km from Louisiana. It is owned by Noble Amos Runner and at a height of 106 meters (there is no residential complex on the platform) is capable of drilling at a depth of 9700 m.

Off the coast of Norway at the bottom of the North Sea is one of the richest deposits of oil and gas. Nature was challenged by man to build such a structure in the open sea that could withstand severe storms and ensure the stability of the platform serving to extract rich fuel supplies from the seabed.

Today we’ll talk about the Troll gas production platform. It is the highest concrete offshore platform in the world. You can get to the platform only by helicopter, dressed in a life suit. The Troll gas field is located 60 kilometers off the coast of Norway. Natural gas reserves formed here 130 million years ago. These huge reserves of gas required the construction of some permanent structure, which would have sufficient strength to conduct gas production from it for over 50 years.

This is the tallest building that has ever moved, relative to the surface of the Earth, and is one of the highest and most complex technical projects in history. The story about towing a platform to the North Sea in 1996 became a television sensation.

The Troll platform was towed more than 200 km from the Chans, in the northern part of Rogaland, to the Troll region, 80 km northwest of Bergen. The tow took seven days.
  Produced gas is carried through platform pipelines at a speed of up to 2,000 miles per hour (890 m / s). This speed is provided by two gas compressors in order to increase production volumes.

In 1996, the platform set the World Record (Guinness Records) as ‘the largest offshore gas platform’.

In 2006, the platform company hosted a concert for workers. The singer Katie Melua was invited, who had to conduct "The Deepest Concert in History". Depth was 303 meters below sea level.

Four cyclopeanic concrete supports protrude from the sea. The drill deck and the entire superstructure of the platform rest on four massive concrete pillars that go down to the seabed to a depth of 300 meters. The base of the platform is made of 19 precast concrete blocks made on land. The base was towed on the ropes and flooded in a deep fjord, where they were joined by four high supports. The total height of each support is 369 meters, exceeding the height of the Eiffel Tower. By the way, in   Each of them has an elevator, the rise of which takes up 9 minutes. The walls of the cylindrical legs have a thickness of more than 1 meter.

Then the entire structure was loaded into the fjord to an even greater depth, and a platform was placed above the structure using barges. Then, ballast water was pumped out of the structure and allowed it to float a few centimeters and dock with the platform. Then the entire new completed structure was raised to the surface and prepared for the journey to the Troll deposit. The platform was towed to the open sea, and it became the largest structure that in the history of mankind has ever been moved from place to place.

Being on a helipad, at an altitude of 76 meters above sea level, you can easily forget that most of the structure is under water. This is a bit like an iceberg. The height of the helipad exactly matches the height of the famous Empire State Building.

Such an offshore platform is a real chemical plant, and since it is an industrial enterprise, one cannot do without a set of protective clothing. At the bottom is a gas production plant, and a little further, a gas processing plant, in the middle of a drilling rig. All production wells are still undiscovered on this new platform, eventually there will be 39 of them. Having overcome the distance to the seabed, the Boers plunge into it to a depth of one and a half kilometers. Wells are located within a radius of half a kilometer around the platform.

Drill trunks weigh like clothes in a wardrobe and are always ready to use. On average, it takes a month to drill each well. However, first of all, we are not interested in this, but what makes the entire structure stable.

Journey to the seabed can be done on an elevator that walks inside one of the giant pillars. When you are surrounded by the sea from all sides, you get the feeling that you are on another planet. On land, we also see tall buildings, gigantic tunnels and other cyclopean structures, but surrounded by the sea the scale of this achievement of engineering is perceived as truly extraordinary. There is a feeling that on no planet there is such a place where people could not penetrate.

The pressure of the sea water column behind the wall is 30 times higher than the pressure inside the structure at the seabed and it would seem to crush the support. The reason this does not occur is the combination of the strength of heavy reinforced concrete and the cylindrical shape of the support. This form is best suited to resist this kind of pressure. It is for this reason that the hull of the submarine and the fuselage of the aircraft have the same shape.

At the very base of the platform, pipelines go around a corner and, passing along the seabed, deliver gas to Norway 60 kilometers from this place. And below the concrete floor, and underneath the sea silt, the platform goes deep into the seabed. It resembles inverted coffee cups, a total of nineteen, each deeply pressed into the sea silt. Imagine an overturned mug pressed into the dirt, when you try to remove it from there, the suction force will firmly hold the cup in place. this is the principle of fixing the base of the structure.

Below, at the bottom of the seabed, the main task will cope with the pressure of the water column, and at the top close to the top, with the wind and waves that fall on the platform. During a storm, waves can reach a deck located 30 meters above the sea. But this deck is large enough not to be flooded by the waves, and securely attached to the four supports. They, in turn, are strong enough to withstand the blows of 5 million waves every year.

It is such structures as the giant Troll platform and the progress of engineering that is behind all this that give confidence that we can live and work anywhere in the sea, under any conditions. This is not so much about how a person can hide from the sea, but how to coexist with him on the coast and in open waters.

Today I will talk about how the Marine Ice-Resistant Stationary Platform (MLSP) is structured using the oil platform in the Caspian Sea as an example, let's see how oil is produced in the sea.Although the platform is almost in the center of the Caspian,ubina is only 12 meters here. The water is clear and the bottom is clearly visible from a helicopter.
This rig began to pump oil a little less than a year ago on April 28, 2010 and is designed for 30 years of operation. It consists of two parts, interconnected by a 74-meter bridge:

In a residential block measuring 30 by 30 meters, 118 people live. Work in 2 shifts of 12 hours a day. The shift lasts 2 weeks. Swimming and fishing from the platform is strictly prohibited, as well as throwing any garbage overboard. Smoking is allowed only in one place in the residential block. A bull-calf thrown into the sea is immediately fired:

The residential block is called LSP2 (Ice-Resistant Stationary Platform), and the main drilling unit is LSP1:

It is called ice-resistant, because in winter the sea is covered with ice and it is designed to withstand it. The hose you see in the photo is the sea water that was used for cooling. She was taken from the sea, driven through pipes and returned back. The platform is built on the principle of zero reset:

A support vessel is constantly running around the platform, capable of taking all people on board in the event of an accident:

Workers are delivered to the station by helicopter. Fly hour:

Before the flight, everyone is instructed, and fly in life jackets. If the water is cold, then wetsuits are also forced to wear:

As soon as the helicopter lands, 2 water hoses are sent to it - they are very afraid of fires here:

Before arriving on the platform, all arrivals undergo mandatory safety training. We had an extended briefing for us, since we got to the platform for the first time:

You can move around LSP1 only in helmets, work boots and jackets, but in the residential block you can walk at least in home slippers, which many do:


The offshore platform is an object of increased danger, and a lot of attention is paid to security here:

There are lifeboats on the residential block and on LSP 1, each of which holds 61 people. There are 4 such boats on residential LSP2 and 2 on LSP1, that is, all 118 people can safely fit on rescue equipment - this is not for you the Titanic:

Passengers from the ship are lifted in a special "elevator", accommodating 4 people at a time:

In each room on each deck there are signs of the direction of evacuation - red arrows on the floor:

All wires are neatly cleaned, low ceilings or steps are indicated by red and white striped markings:

At the end of our tour, I learned that this platform was completely built with us. I was surprised, because I was sure that she was a "foreign car" - she didn’t smell like a scoop here. Everything is done very carefully and with quality materials:

Since there are a lot of photos and information, I decided to split my story into 2 posts. Today I will talk about the residential block, and about the most interesting - about the wells and the production process - in the next post.

By LSP2, the captain himself drove us. The platform is marine, and the main here, like on the ship, is the captain:

In the residential block there is a backup CPU (Central Control Panel). In general, all production management (oil companies put emphasis on O) is carried out from another control panel located on LSP1, and this one is used as a backup:

From the backup console window you can clearly see the working unit:

The captain’s office, and behind the door on the left is his bedroom:

Bedspreads and colored bedding are the only things that discord with the European appearance of the rig:

All cabins were open, although their owners were on shift. There is no theft on the platform, and no one closes the door:

Each cabin is equipped with its own bathroom with shower:

Cabinet of Engineers:

Platform doctor. Mostly sitting idle:

Local infirmary. The helicopter does not fly every day, and in the “case of which” the patient can lie down here under the supervision of a doctor:

A lot of girls work on the platform:

In front of the dining room everyone washes their hands:

In the dining room there were 4 options for lunch to choose from:

I chose the "Goodbye Diet" triangular dumplings:

The supply of food and water allows the platform to exist autonomously for 15 days. Alcohol is strictly prohibited, since in an emergency all people should be in good condition.

All management of the Marine Ice-resistant Stationary Platform (MLSP) occurs from the Central Control Panel (CPU):


The whole platform is stuffed with sensors, and even if somewhere in the wrong place the worker lights a cigarette, they will immediately know about it in the CPU and, a little later, in the personnel department, who will prepare an order to dismiss this wise guy even before the helicopter delivers it big land:

The upper deck is called Pipe. Candles from 2-3 drill pipes are collected here and the drilling process is controlled from here:

The pipe deck is the only place on the rig where there is at least some hint of dirt. All other places on the platform are torn to shine.

The big gray circle on the right is the new well that is currently being drilled. It takes about 2 months to drill each well:

I have already described the drilling process in detail in a post abouthow oil is extracted:

Chief driller. He has a wheelchair with 4 monitors, a joystick and various other cool things. From this miracle chair, he controls the drilling process:

Pumps pumping drilling mud under a pressure of 150 atmospheres. On the platform there are 2 working pumps and 1 spare pump (about why they are needed and the purpose of other devices, read the article onhow oil is extracted):

The cone is a chisel. It is she who is at the tip of the drill string:

Using the drilling fluid pumped by the pumps from the previous photo, these teeth are rotated, and the gnawed rock is carried upstairs with the used drilling fluid:

At present, 3 oil, 1 gas and 1 water wells are already operating on this drilling platform. Another well is in the process of drilling.

Only one well can be drilled at a time, and there will be 27 in total. Each well is from 2.5 to 7 kilometers long (not depth). The oil reservoir lies 1300 meters underground, so that all wells are horizontal and like tentacles diverge from the drilling:

The production rate of wells (that is, how much oil it pumps per hour) is from 12 to 30 cubic meters:

In these separator cylinders, associated gas and water are separated from oil, and at the outlet after running through an oil treatment unit that separates all impurities from oil, marketable oil is obtained:

From the Platform, an underwater pipeline with a length of 58 kilometers was laid to a floating oil storage facility installed outside the ice zone of the Caspian:

The main pumps are pumped into the pipeline:

These compressors pump associated gas back into the reservoir to maintain reservoir pressure, which pushes oil to the surface, respectively, the oil recovery becomes greater:

The water that was separated from the oil is cleaned of mechanical impurities and returned back to the reservoir (the same water that was pumped out of the bowels)

Pumps of 160 atmospheres pump water back into the reservoir:

The platform has its own chemical laboratory, where all parameters of oil, associated gas and water are monitored:

The drilling rig is supplied with electricity by 4 turbines operating from associated gas, with a total capacity of about 20 MEGAWATT. In the white boxes of the turbine, 5 megawatts each:

If the turbines are cut off for some reason, the backup diesel generators will feed the rig:

The switchboard occupies 2 floors:

Special boilers burn the exhaust from the turbine and heat the residential complex with it. That is, even the exhaust, like a car from a silencer, is disposed of and zero pollutants enter the atmosphere:

We found a rare moment when associated gas was simply burned on a flare boom, since concrete was poured between the walls of the well and the casing at that time, and in general, 98% of the associated gas is used for our own needs:

So we figured out how the stationary offshore oil drilling platform works.
