According to industry sources in June 1018, Pemex may try to secure JV partners to help develop a farm-out package of offshore heavy oil fields, including assets like the shallow water Utsil and Ayatsil-Tekel trend. First discovered in 2006, the Ayatsil-Tekel complex has total reserves of 1.62 million boe and 1P reserves of 544 million boe. The trend hosts oil with less than or equal to 11 degrees API gravity. The Bay of Campeche heavy oil trend known covers some 88.8 sq km. Pemex may also re-offer the Ayin-Batsil (CNH-A2-AYIN-BATSIL/2017) contract. No timeline is available, but a competitive bidding process for these heavy oil fields could be announced in H2 2018/H1 2019. A previous attempt to farm-out the Ayin-Batsil contract on 4 October 2017 failed to draw any bids. The competitive farm-out process was handled by the Comision Nacional de Hidrocarburos (CNH). First discovered by Pemex, the Ayin-Batsil cluster lies in the Bay of Campeche. Pemex has said the contract area holds 359 MMboe in 3P reserves (and 224 MMboe in prospective resources). The Ayin-Batsil play covers 1,096 sq km. Batsil is located in water depth of 82m and Ayin in 176m.
