PetroRio spudded the POL-N (9-POL-042D-RJS) directional new-pool wildcat (NPW) in the Polvo production concession on 5 November 2019 and completed the well as an oil discovery on 3 December 2019 at a final total depth (TD) of 5,019 m measured depth (MD) and 2,135 m true vertical depth (TVD). The operator reported the following information regarding the well on 3 February 2020.    The NPW was spudded from the Polvo      A fixed platform and the bottom hole location (BHL) target located      approximately 2.5 km south-west in the stratigraphically higher Eocene      Embore target and 3.8 km west south-west of the Quissama Formation target      in the Ipanema prospect.   The NPW discovered oil in the      Eocene Embore Formation and in the Quissama Formation at the Ipanema      prospect. PetroRio reported that it had 76 m of net vertical pay in the      Quissama Formation with 18% porosity.   The operator then drilled the      POL-Nb (7-POL-44HP-RJS) horizontal development well in the Quissama      Formation and tested the zone but reported it flowed high viscous oil and      it was testing the oil to design a chemical treatment to attempt to      improve the flow rate of the reservoir. The development well was spudded      on 13 December 2019 and completed on 6 January 2020 at a final total depth      (TD) of 5,816 m measured depth (MD) and 1,900 m true vertical depth (TVD).      Once it concludes its testing of the Quissama Formation, post chemical      treatment, it plans to test the oil shows in the Embore Formation that had      45 m of net vertical pay.   The operator did not report any      reserve estimates, but from the information published by PetroRio, the      possible reserves estimated by IHS Markit for the Quissama Formation of      the Ipanema prospect is original oil in place (OOIP) of 39 MMbo and      original gas in place (OGIP) of 4 Bcfg with estimated possible 2P      recoverable reserves of 8 MMbo and 2 Bcfg. The possible reserves estimated      by IHS Markit for the Embore Formation is original oil in place (OOIP) of      19 MMbo and original gas in place (OGIP) of 4 Bcfg with estimated possible      2P recoverable reserves of 4 MMbo and 2 Bcfg.  PetroRio holds 100% working      interest in the Polvo production concession.   PetroRio spudded the POL-Na (9-POL-043DP-RJS) directional new-pool wildcat (NPW) in the Polvo production concession on 4 December 2019 and completed the well on 11 December 2019 at a final total depth (TD) of 4,455 m measured depth (MD) and 2,134 m true vertical depth (TVD). The NPW drilled the Eocene Embore Formation oil zone also and targeted the Quissama Formation in the Leblon prospect. It was drilled from the same surface location as the POL-N (9-POL-042D-RJS) NPW and was side-tracked from that wellbore. The operator did not report any reserve estimates, but from the information published by PetroRio, the possible reserves estimated by IHS Markit for the Quissama Formation of the Leblon prospect is original oil in place (OOIP) of 16 MMbo and original gas in place (OGIP) of 2 Bcfg with estimated possible 2P recoverable reserves of 3 MMbo and 1 Bcfg.
