Exploration and production activities in the United States are regulated by concessions.


Gulf of Mexico

Eni holds interests in 62 exploration and production blocks in the shallow and deep offshore of the Gulf of Mexico, of which 26 are operated by Eni.

Production The main operated fields are Allegheny and Appaloosa (Eni’s interest 100%), Pegasus (Eni’s interest 85%), Longhorn, Devils Towers and Triton (Eni’s interest 75%). Eni also holds interests in Europa (Eni’s interest 32%), Medusa (Eni’s interest 25%), Lucius (Eni’s interest 8.5%), K2 (Eni’s interest 13.4%), Frontrunner (Eni’s interest 37.5%) and Heidelberg (Eni’s interest 12.5%) fields. In 2018,  production amounted to 35 kboe/d net to Eni.

Development Development activities concerned the Lucius Subsequent Development with the drilling and completion of three submarine productive wells, which will be linked to the production platform of the Lucius field and upgrading of existing facilities.



Production Production comes from the Alliance area (Eni’s interest 27.5%), in the Fort Worth Basin. This asset includes unconventional gas reserves (shale gas). In 2018, Eni’s production amounted to approximately 4 kboe/d.



Eni holds interests in 166 exploration and development blocks in Alaska.

In August 2018, Eni was awarded a 100% interest of 124 licenses in Alaska. The exploration licenses are located in the Eastern North Slope in Alaska with high mineral potential and nearby to existing production facilities.

In December 2018, Eni signed an agreement to purchase of 70% interest and the operatorship of the Oooguruk field, where Eni already holds 30% interest. The agreement has been finalized in 2019.

Production The main fields are Nikaitchuq (Eni operator with a 100% interest) and Oooguruk fields with a 2018 overall net production of 17 kbbl/d.

Gas & LNG Marketing & Power

In May 2009, Eni signed a strategic alliance with Quicksilver Resources Inc., an independent natural gas producer in the USA, for the acquisition of a 27.5% interest in the Alliance area, located between the cities of Fort Worth and Dallas in Northern Texas. The area extends for roughly fifty square kilometres with the production of unconventional gas coming from the clay (shale gas) of the Barnett Shale formation in the Fort Worth Basin. The gas is located at an average depth of about 2,300 metres. Quicksilver will retain 72.5% and operatorship of the properties included in the Alliance. The alliance with Quicksilver foresees that exchange of techniques and know-how between the two companies, in particular for technologies relating to drilling, the completion of wells and geophysics. Eni is also entitled to a stake of 27.5% in any future additional licences that Quicksilver may acquire in an area of mutual interest around Alliance, which covers over a thousand square kilometres.


Natural gas liquefaction (LNG) plants in Cameron

In the third quarter of 2009 the Cameron re-gasification plant, eighteen miles from the Gulf of Mexico along the Calcasieu Channel in Hackaerry, Louisiana, came into operation. In view of changed market conditions, in March of 2010, Eni redefined with the US company Cameron LNG, certain aspects of the original agreement signed in 2005. The agreement foresees that Eni has a total of about 5.7 billion cubic metres a year and a dedicated LNG storage capacity of approximately 160 thousand cubic metres, elements that give Eni greater flexibility in managing seasonal swings in demand. One of the objectives of the operation remains the marketing in North America of Eni’s natural gas reserves under development in Africa. 


The Pascagoula terminal

As part of the upstream project for the construction of a liquefaction plant in Angola for the North American market, Eni has signed a twenty-year contract (2011-2031) with Gulf LNG for the purchase purchase of volumes of re-gasified gas at the Pascagoula plant (United States) over a twenty-year period (until 2031).

In 2018, Eni's sales of natural gas in the United States amounted to 1.74 billion cubic meters
