We operate in the country with a 100% interest in the Area 1 operating licence, where activities for the development of the Amoca, Miztón 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 to swap participating interests with Lukoil, assigning 20% of Eni's share in Area 10 licences and acquiring 40% of Area 12, operated by Lukoil. The swap was approved by the Comisión Nacional de Hidrocarburos (CNH) in July 2019. Also in 2018, we were assigned licences for Area 24, with a share of 65%, and Area 28, with a share of 75%, and we are operator in both.
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 in Mexico is regulated by production sharing agreements (PSAs) and a concession contract for the Area 24 licence. The development plan for the three discoveries at Amoca, Mitzón and Tecoalli was approved by the country's authorities in July 2018. The work took place in phases. Early production started in June 2019, with a platform installed and a connection facility to an existing onshore treater built. Initial production was around 8,000 barrels a day, and in 2020 we reached 20,000 barrels a day. Finally, the full field development phase involves installing 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.
In 2020 the development activities concern the full field development program of the operated license Area 1 (Eni’s interest 100%), already in production. Development drilling activities are ongoing and during 2020 were completed producing wells which were linked to the Miztón production platform. A subsequent development phase of the project includes the production start-up of the Amoca discovery by means of the installation of a new leased production platform. During the year, the FEED phase for these two production platforms started up.
In August 2021 we announced an oil find on the Sayulita Exploration Prospect in Block 10, located approximately 70 kilometers off the coast and just 15 km away, from the previous oil discovery of Saasken. An intensive data collection has been carried out on the well and the data acquired indicate a production capacity for the well of up to approximately 3,000 barrels of oil per day.
In February 2022 Miamte Floating Production, Storage and Offloading (FPSO) started hydrocarbon production at the Miztón field, within the Development Project in Area 1. The FPSO will allow to increase the country’s production with an economical benefit for Mexico. Following the first hydrocarbon introduction into the FPSO and two more platforms start-up in Amoca and Tecoalli fields, production will ramp up till the full field development will be completed by 2024. The FPSO has an oil treatment capacity of 90 kbopd and gas treatment capacity of 75MMscfd.
