Well control methods👇🏼
1-Primary-By mud weight to avoid kick.
2-Secondary- By mechanical devices called-BOPS
3- Tertiary- To control underground Blowouts by Heavy muds or drilling Relief wells etc

Guys, For those who are unaware of marks distribution 👇🏼👇🏼
ONGC 100 Marks= (60% of GATE Score+ 25(max degree marks)+15(interview marks)
ONGC 100 Marks= (60% of GATE Score+ 25(max degree marks)+15(interview marks)
For example👇🏼
If Sandeep has completed B.Tech in Petroleum Eng. & got AIR-6 in GATE, with a GATE score=897 out of 1000.
and also he got 14 marks out of 15 in ONGC panel Interview.
Then his aggregated marks out of 100 during recruitment will be.
(897*.06) + (20, only B.Tech)+ 14(interview marks)= 87.82/100.
& This 87.82 marks will be compared with other candidates.
So, Whatever your GATE rank may be, if there is not much difference in GATE scores , you can see here the importance of interview marks then.
Hope all understood it now.😇

Subsea wells may be installed individually, in a clusters, or on a template where the reservoir fluids from all the wells are channeled to a manifold that is tied back to a host platform.
Template System: A subsea production facility where the wells, connectionsand manifolds are on a common supporting structure or template.
Cluster Well System: A centrally located manifold around which independent satellite wells are clustered. These wells individually connect to theproduction manifold.
Which type of system is shown above ?
