PEMEX plugged and abandoned the Koban 1DEL directional outpost well, the first outpost of the gas and condensate discovery the Koban 1 directional new-field wildcat (NFW) in the AE-0019 block during late-March 2019.Â  The final status of the well has not been reported but it may be temporarily abandoned or non-commercial.Â  The operator had extensive testing operations planned for the outpost.    The directional outpost reached a total depth of      6,729 m measured depth (MD) and 6,472 m true vertical depth (TVD) in      November 2018. Â        The      outpost was spudded on 10 July 2018.        The outpost had a modified proposed      total depth (PTD) of 6,676 m and will test the Middle Cretaceous and      Jurassic formations.    The      well was drilled by the âCantarell IIâ J/U in a water depth of 11 m. Â     It      is located approximately 1.9 km south of the Koban 1 discovery well.    The drilling permit for the outpost      was granted on 25 June 2018. Â     The      drilling cost estimate was reported to be USD 36.21 million at an exchange      rate of 1USD = 18.5 MXN and the completion cost is USD 22.0 million and is      high due to two cased-hole production tests being planned.  After      the Koban 1DEL is drilled to TD and cased for testing, PEMEX will first      conduct a test of the Jurassic reservoir.Â       The operator will flow the well for three 15-hour periods for      clean-up then shut the well in for four hours.Â  The third stage is to flow the well for      10 hours each through different choke sizes of 16/64â, 24/64â, and 32/64â      and taking the PVT measurements.Â       The final stage is a second shut-in period of 10 hours and take the      final SITP.Â  A similar test will be      conducted on the Cretaceous reservoir but with 10-hour flow periods for      the first clean-up stage.Â  The test      will be conducted by the drilling rig and will be directed to an FPSO through      a multi-phase pipeline.    SENER      awarded the AE-0019-M-Okom-02 entitlement to Pemex 100% through Ronda 0 on      27 August 2014. The block covers an approximate area of 976.40 sq km.     On 23 August 2018, the CNH approved the evaluation plan for the Koban 1 gas and condensate discovery in the AE-0019-M-Okom-02 entitlement block as submitted by PEMEX which includes the drilling of the Koban 1DEL and conducting two cased-hole production tests, one in the Cretaceous reservoir and one in the Jurassic reservoir. As part of its evaluation plan PEMEX will conduct two extended well tests on the outpost, one in the Cretaceous reservoir and one in the Jurassic reservoir.Â  PEMEX reported that the Koban 1 discovered two gas and condensate reservoirs, the first in the Cretaceous at 5,754 m and the second in the Upper Jurassic Kimmeridgian at 6,270 m. Â The condensate is 42.9Â° API gravity.Â  The Cretaceous reservoir is characterized as a re-crystalized, bioclastic and fractured wackestone while the Jurssasic reservoir is a meso-crystalline dolomite.Â  The Cretaceous structure covers an estimated closed area of 19.5 sq km while the Jurassic structure is larger at 24 sq km. The original surface volumes of gas and condensate for the Cretaceous reservoir is reported to be 321 Bcfg and 61 MMbc while the Jurassic reservoir volumes are estimated to be 722.5 Bcfg and 152.21 MMbc.Â  A recovery factor estimate of 50% gives the field potential recoverable reserves of 160.5 Bcfg and 30.5 MMbc for the Cretaceous reservoir and 361.24 Bcfg and 76.1 MMbc for the Jurassic or a total for the field of 521.75 Bcfg and 106.6 MMbc.   On 31 March 2017, PEMEX suspended as a gas and condensate discovery the Koban 1 directional new-field wildcat (NFW) in the AE-0019 block in the Sureste Basin.Â  PEMEX reported on 3 May 2017 with its 1st quarter 2017 results that the well tested 11 MMcfg/d and 3,276 bc/d.Â  The CNH reported that the well was completed in a 67 m interval from 6,164 m to 6,231 m in its Jurassic formation target.Â  The agency reported that the well had a pressure of 8,691 psia, assumed to be bottom hole pressure (BHP).Â  The CNH further reported that another 61 m zone was tested from 6,314 m to 6,375 m but gave no details.Â  The well reached a final total depth (TD) of 6,587 m measured depth (MD) and 6,425 m true vertical depth (TVD) on 3 March 2017.Â  The operator conducted testing operations on the well during March.Â  The well was spudded on 2 August 2016. The NFW had a proposed total depth (PTD) of 6,737 m.Â  The âCantarell Iâ J/U drilled the well in a water depth of 21 m.Â  The Middle Cretaceous and Jurassic formations were the primary objectives. The Middle Cretaceous Formation target is located from 5,560 m to 5,890 m while the Upper Jurassic is located from 6,030 m to 6,560 m. The reported reserve estimates for the prospect were 91 MMboe. On 27 January 2016, the CNH approved plans by PEMEX to drill the Koban 1 new-field wildcat (NFW).Â  The well is a high temperature, high pressure well located on a northwest to southeast trending anticline nucleated by a salt body.Â  The planned spud of the well was originally scheduled for February 2016.Â  The well is located in the southeastern area of the block. The nearest well is the Cosaco 1 located 6.6 km south-east in the A-0340 â Campo Tizon enclave production block.
