On late June 2020, is assumed PEMEX reached the sidetrack proposed total depth (PTD) of 2,830 in the Chi 1EXPST New Pool Wildcat (NPW) located in the AE-0153-Uchukil entitlement, offshore Sureste Basin. As of 8 July 2020, no further information was released about this well. PEMEX holds 100% interest in this block.  The sidetracked well had a proposed total depth (PTD) of 2,830 m measured depth (MD) and 2,000 m true vertical depth (TVD). The target was the Middle Pliocene at 2,058 m measured depth to evaluate prospective resources of 9 MMboe with 58% of Geological Chance of Success. The hydrocarbon expected was oil around 17Â° API.  The "CME-1" jackup, which drilled the original vertical well, also drilled the sidetracked well section on water depth of 27 m. The estimated sidetrack section total cost was USD 5.4 million, which includes USD 4.5 million (13 days) for drilling and USD 0.9 million (6 days) for completion or abandon.  On 28 August 2019, SENER officially granted the entitlement for this block AE-0150-Uchukil.    On 02 October 2019 CNH approved its first exploration plan.   On 20      February 2020, PEMEX was granted approval by the CNH to drill the Chi 1EXP      new-field wildcat (NFW).  Â On 14 May 2020, PEMEX was granted      approval by the CNH to sidetrack the Chi 1EXP new-field wildcat (NFW) at      750 m to complete the Middle Pliocene section evaluation because one of      the most important Middle Pliocene interval is absent due to a normal      fault.
