The story

ENL was first founded on April 26, 2001, when ABB and ExxonMobil signed an agreement for ABB to design the front-end systems of the Sakhalin-I project's first phase. ENL was formally declared as commercial on October 29 of that same year, representing a $12 billion USD ($20 billion today) investment, the largest foreign direct investment into Russia at the time.

Across the 2000s, ENL awarded multiple contracts for logistics relating to the project, including Amur Shipbuilding Plant, Sakhalinskiye Aviatrassy, Fesco Transport, Vostok Aviation, Sovcomflot, and Lukoil. On July 12, 2003, ENL began drilling at the Chavyo wellsite, the project's first extended-reach drillsite. Later in 2005, ExxonMobil announced that ENL has start up production on the project, and that by 2006, the project could produce 250,000 barrels per day.

In 2007, ENL broke a world drilling record for the world's longest extended-reach oil well at 37,016 feet; it superseded its record in 2008 by 1,306 more feet. Also in 2007, ENL announced it had passed 100 million barrels produced from Sakhalin.
