We operate in the country with a 100% interest in the Area 1 operating licence, where activities for the development of the Amoca, Mizton and Tecoalli discoveries are underway. In 2019, we started early production of the Miztón field, the first step in the development of an oil hub with resources in place estimated at 2.1 billion equivalent barrels. Start-up began less than two and a half years from drilling the first well and less than a year from the approval of the development plan, demonstrating the effectiveness of our fast track model. In addition, we operate in Areas 10 (Eni's interest 80%), 14 (Eni's interest 60%) and 7 (Eni's interest 45%), located in the Sureste basin. In 2018, we signed agreements, which were subject to the approval of the country's authorities for the swap of interests with the Lukoil company, with the sale of 20% of Eni's interest in the Area 10 licences and the acquisition of a 40% interest in Area 12 operated by Lukoil. The swap of contractual interests was approved by the Comisión Nacional de Hidrocarburos (CNH) in July 2019.
Again in 2018, we were assigned licences for Area 24 with a share of 65% and Area 28 with a share of 75%, we are operators in both. Exploration and development activities in the country are regulated by Production Sharing Agreements (PSA) and a concession contract for the Area 24 licence. The development plan for the three Amoca, Mitzón and Tecoalli discoveries was approved by the country's authorities in July 2018. Activities are carried out in phases, with the early production start-up taking place in June 2019, through the installation of a platform and the construction of a connection facility to an existing onshore treater. Initial production was expected to be around 8 thousand barrels per day, while currently we are at 15 thousand barrels per day. Finally, the full field development phase includes the installation of three additional platforms and a floating production, storage and offloading unit (FPSO).
In February 2020 announced a new oil discovery on the Saasken Exploration Prospect in Block 10, located in the mid-deep water of the Cuenca Salina in the Sureste Basin, Offshore Mexico. Saasken-1 NFW is the sixth consecutive successful well drilled by Eni offshore Mexico. According to preliminary estimates, the new discovery may contain between 200 and 300 million barrels of oil in place.
