A 'Notice of Discovery and its Commerciality' for the Absheron discovery was submitted on June 1 on behalf of the Socar/Total/GDF Suez partnership by operator Total E&P Absheron.
This step is an important milestone in the frame work of the Agreement on Exploration, Development and Production Sharing for the Absheron offshore block in the Azerbaijan sector of the Caspian Sea (EDPSA) signed on February 27, 2009. It is a confirmation of the importance of the discovery, announced in September 2011, on the Absheron X-2 well.
The well was drilled in 1,555 feet (474 meters) of water depth and reached a depth of 22,550 feet (6,874 meters). One of the hydrocarbon bearing intervals was tested at 960 thousand cubic meters per day of non-associated gas. During this production test, nearly 2,500 barrels per day (400 cubic meters per day) of a 42.5-degree API condensate were also produced.
The well results indicate gas resources of between five to 10 trillion cubic feet (150 and 300 billion of cubic meters) - of non-associated gas with condensates in the Balakhany and Fasila formations on the Northern compartment of the structure. The elongated structure straddles approximately 105 square miles (270 square-kilometers) and the cumulative net pay is greater than 525 feet (160 meters) thick.
Operations on Absheron X-2 wells are continuing with the drilling of a side track toward the northern part of the structure.
Yves-Louis Darricarrère, President of Total's Exploration & Production business, commented: "This declaration of commerciality is the result of the success of our more aggressive exploration program and our desire to bring discovered hydrocarbons rapidly into production. It marks an important step in our activities as operator in Azerbaijan and our good cooperation with Socar and GDF Suez."
The Absheron field is located around 62 miles (100 kilometers) southeast of Baku and could be developed with a limited number of wells for a first phase of development. The work program of the partnership now includes studies and surveys to better dimension this development. A 3D seismic campaign will be shot in 2013 and more appraisal wells may be drilled to better assess the extent and the geometry of the structure.
Total subsidiary, Total E&P Absheron is the operator of the Absheron license with 40 percent equity. The partners are Socar (40%) and GDF Suez (20%).
