Nabucco said in an interview with Natural Gas Europe in May 2013 that "Nabucco is continuing to cooperate with the International Financial Institutions to ensure the bankability of the project, a large part of the legal due diligence has already been completed. A Letter of Intent has been signed with the IFIs most recently". In a separate interview in February 2013, Mitschek confirmed that all legal and regulatory framework approved for the original Nabucco project would remain valid for Nabucco West. Supply sources The potential suppliers for original Nabucco project were considered to be Iraq, Azerbaijan, Turkmenistan, and Egypt. At the first stage, of natural gas per year were expected from Iraq. Iraqi gas would be imported via the Arab Gas Pipeline (extension to be built) from the Ekas field. Turkmenistan would provide of gas per year through Iran or across the Caspian Sea via the planned Trans-Caspian Gas Pipeline. OMV and RWE set up a joint venture, named the Caspian Energy Company, to carry out research for a gas pipeline across the Caspian Sea. In the long term, Kazakhstan may become a supplier providing natural gas from the Northern Caspian reserves through the planned Trans-Caspian Gas Pipeline. Egypt could provide of natural gas through the Arab Gas Pipeline. Prime Minister of Turkey Recep Tayyip Erdoğan has urged Egypt to export natural gas to Europe via the Nabucco pipeline. Iran has also proposed to supply gas to Nabucco pipeline and this was backed by Turkey; however, due to the political conditions this is rejected by the EU and the United States. Nabucco-West is designated to carry Azeri gas from the second stage of Shah Deniz through TANAP pipeline. The pipeline is able to transport between 10 – 23 BCM annually from the Shah Deniz gas field. OMV, a shareholder in Nabucco, also suggested that Nabucco will be used to transport gas from its Domino-1 deep-sea offshore well in the Black Sea. The Domino-1 well was OMV's largest gas find with 1.5 – 3 trillion cubic feet announced in February 2012.
