On 9 October 2018, PEMEX reported it completed as an oil and gas discovery the Mulach 1EXP new-field wildcat (NFW) in the AE-0051-4M-Mezcalapa-01 entitlement block.Â      The      NFW reached a final total depth (TD) of 3,976 m and it was officially      completed on 30 September 2018.Â    The      operator reported that it drilled five reservoirs of light oil in the      Upper Miocene and tested the well for 3,748 bo/d and 800 Mcfg/d.Â    The      CNH reported that the reservoir interval perforated was from 3,323 m to      3,347 m.Â    The      NFW reached a final total depth (TD) of 3,976 m.Â  PEMEX indicated it estimates 3P reserves      for the discovery of 100 MMboe.       The NFW was spudded on 10 July      2018 in a water depth of 21 m. Â On 2 July 2018, the CNH approved a      drilling permit for the NFW.       The well was targeting the      Miocene Formation at a proposed total depth (PTD) of 4,040 m.Â  The unrisked prospective resources were      120 MMboe and represents the best prospect out of the six prospects      identified within the block. It is located in the very northeastern corner      of the block about 7.5 km south-west of the Yaxche field, the nearest      Miocene producing field.    On 20 June 2018, the CNH      approved the modification of the exploration plan for the additional      two-year exploration period submitted by PEMEX for the      AE-0051-4M-Mezcalapa-01 entitlement block.Â       The modified exploration plan for the block includes the addition      of the drilling of the Mulach 1EXP well in the north-eastern area of the      block.     The AE-0051 block had its      original phase extension exploration plan approved on 10 October 2017.Â  The other five prospects include the      offshore Chejekbal 1EXP, Coatzin 1EXP, Tlamatini 1EXP, and deeper pool      wildcat (DPW) Tetl 1001EXP.Â  There      is one onshore prospect, the deeper pool wildcat (DPW) Tupilco      3001EXP.Â  The prospects are      targeting the Tertiary and deeper Cretaceous and Jurassic plays.      The AE-0051-4M-Mezcalapa-01 entitlement block was originally granted to PEMEX on 27 August 2014 with a two-year extension granted on 27 August 2017.Â  The block covers an approximate area of 652.77 sq km after being reduced due to environmentally sensitive areas located within the central area of the onshore-offshore block.
