Exxon sets world record with the deepest oil well on the Russian shelf
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.
