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. Â The operator continues testing the well after a frac job.    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 is reported to be 18 MMboe with a      proposed drilling and completion cost estimated at approximately USD 13.4      million.        PEMEX plans to drill a 1,500 m horizontal leg and frac      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.
