PEMEX completed as an oil and gas discovery the Semillal 1EXP horizontal new-field wildcat (NFW) in the AE-0070 block in the onshore Burgos Basin during early-October 2018 and continued flow back after a frac job and testing of the well during late-December 2018.    In December 2018, the operator was testing      the well at approximately 873 bo/d, 8.47 MMcfg/d, and 27 bw/d.Â  Cumulative oil production from testing      operations so far are reported to be approximately 56,500 bbls. Â   In November 2018, the operator was testing      the well at approximately 900 bo/d, 6.8 MMcfg/d, and 19 bw/d.Â  The API oil gravity is 29Â°.       The NFW was spudded on 15 April 2018.     This represents the first      unconventional horizontal well spudded in the country since 2014, while      operators waited for the environmental regulations to be approved.       The NFW had a proposed      total depth (PTD) of 3,690 m measured depth (MD) and 2,150 m true vertical      depth (TVD).        The      Upper Jurassic Pimienta Formation was the primary objective.       The      prospect size was reported to be 18 MMboe with a proposed drilling and      completion cost estimated at approximately USD 13.4 million.        PEMEX      drilled an 1,800 m horizontal leg and fract it with up to 15 stages.       PEMEX      attempted to obtain approvals for horizontal unconventional wells in 2015      but it was delayed for environmental reviews regarding the activity.       The      well is located in the southwestern area of the block about 800 north-west      of the Buenos Aires 1 well.    SENER      granted the AE-0070-2M-Anhelido-02 entitlement to Pemex 100% through Ronda      0 on 27 August 2014. The block covers an approximate area of 926.74 sq km.     On 20 February 2018, the CNH approved the drilling permit for PEMEX to drill the Semillal 1EXP horizontal new-field wildcat (NFW) in the AE-0070 block in the onshore Burgos Basin.Â  PEMEX suspended the drilling permit in 2016 due to lack of environmental regulations which have since been published after a two year delay.    On 9 November 2016, the CNH reported that PEMEX requested that its authorization to drill the Semillal 1 horizontal new-field wildcat (NFW) in the AE-0070 block in the onshore Burgos Basin be suspended due to environmental requirements by environmental protection agency ASEA. PEMEX requested the permits be suspended until ASEA issues specific public regulations regarding unconventional drilling activity.Â  Details were not reported regarding the ASEA requirements but are speculated to be very onerous.     On 25 February 2016, the CNH originally approved plans by PEMEX to drill the Semillal 1 horizontal new-field wildcat (NFW) in the AE-0070 block in the onshore Burgos Basin.
