Exxon Neftegas Ltd (ENL) has completed drilling the world’s deepest well in the Chayvo oil field on the Sakhalin shelf in the Russian Far East.

­The shaft of well Z-44 is 12,376 meter deep, which is the equivalent to 15 times the height of the world tallest skyscraper the Burj Khalifa in Dubai.

“We are  proud  of this  achievement,  which  furthers  the successful  implementation of  this remarkable project,”  ENL chief James Taylor is quoted as saying.  Six of the world’s ten deepest wells, including Z-44, have been drilled in Russia for the Sakhalin-1 project using ExxonMobil drilling technology – the so-called “fast drill”, he added.

Chayvo is one of the three Sakhalin-1 fields and is located off the northeast coast of Sakhalin Island in eastern Russia.  The Sakhalin-1 project is being developed by an international consortium led by ENL, which holds a 30% stake,  the Japanese SODECO (30%), India's ONGC Videsh  Ltd (20%) and subsidiaries of Russian oil major Rosneft – RN Astra (8.5%) and Sakhalinmorneftegaz Shelf (11.5%).

The total project is estimated to cost $10–12 billion. The fields of Chayvo, Odoptu, and Arkutun-Dagi are estimated to yield 2.3 billion barrels of oil and 17.1 trillion cubic feet of natural gas.
