Where is Mumbai High? What is Sagar Samrat?

In Maharashtra, about 176 km off Mumbai in the Arabian Sea, there is a huge oil deposit known as Mumbai High.

The syncline of the rock structure in which oil has been struck is higher than the normal height and oil is taken from the depth of over 1,400 m with the help of a specially designed platform known as 'Sagar Samrat'. It is a self propelled jack-up type of drilling platform.
