As oil is produced in the sea (part 2)

• How to extract oil in the sea (part 2)

This is a continuation of the story about how to construct the offshore oil platforms. The first part with the general story of the drill and how to live on her oil here.

All controls offshore ice-resistant stationary platform (MISP) comes with the central control unit (CPU):

The entire platform crammed with sensors, and even if somewhere in the wrong place worker lit a cigarette, it will immediately know the CPU and, later, in the personnel department, who will prepare the order of dismissal of the wiseacre before the helicopter take him to the mainland:

The upper deck is called Pipe. Here are collected the candles of 2-3 drill pipe and hence also control drilling process:

Pipe deck - the only place on the rig, where there is at least some hint of dirt. All the other places on the kick to shine platform.

Big gray circle on the right - a new well that is currently drilled. Drilling each hole takes about 2 months:

I have already described in detail the process of drilling in a post about how oil is produced:

The main driller. He had a chair on castors with 4 monitors, joystick and various other cool thing. From this wonderful chair it controls the drilling process:

pumps pumping drilling pressurized solution 150 atmospheres. On the platform 2 of the pump working and 1 spare (about why they are needed, and the appointment of other devices, read the article about how oil is produced):

cutters - chisel. It is located on the tip of the drill string:

With the help of mud, is pumped to the previous photo, spinning these teeth, and gnaw the rock is carried away upward of spent drilling mud:

At present, the first 3 of oil, gas and 1 1 water well on this rig. Another well is in the process of drilling.

At the same time possible to drill just one well, and all them will be 27. Each well of 2, 5 to 7 kilometers long (not depth). Oil reservoir lies 1,300 meters under the ground, so that all horizontal wells and how the tentacles diverge from the drill:

The discharge of wells (ie, how much oil it pumps per hour) from 12 to 30 cubic meters:

In these cylinders, the separators passing gas and water is separated from oil, and the output after running through an oil treatment, which separates the oil from all the impurities obtained commercial oil:

from the platform laid underwater pipeline length of 58 kilometers to a floating reservoir, installed outside the ice zone of the Caspian Sea:

The pipeline pumps oil pumped Trunk:

These swing compressor gas passing back into the reservoir to maintain the reservoir pressure, which pushes the oil to the surface, respectively, return of oil becomes greater,

The water that is separated from the oil, is purified from mechanical admixtures and recycled back into the reservoir (the same water as the pumped from the interior)

Pumps 160 atmospheres is pumped water back into the formation:

The platform has its own chemical laboratory, which controls all the parameters of oil, associated gas and water:

4 electricity supply drilling turbines operating on associated gas, a total capacity of about 20 megawatts. The white boxes turbine 5 megawatts each:

If the turbine for some reason cuts drilling will supply backup diesel generators:

Switchboard has 2 floors:

Special boilers afterburning exhaust from the turbine and the heat residential complex. That is, even the exhaust as the car of the muffler is disposed in the atmosphere gets zero pollutants:

We found a rare moment when passing a gas burned at the flare boom, since at this time the concrete poured between the borehole wall and the casing, and voobshe, 98% of associated gas is used for auxiliaries:
