On 28 July 2020, PEMEX reported an oil and gas discovery associated with the well Paki 1EXP new-field wildcat (NFW). The well tested 2,364 Mbo/d and 1.5 MMscf/d in the in the interval 2,045-2,053 m, and reached the proposed total vertical depth of 2,140 m. The well is in the AE-0150-Uchukil entitlement, AE-0150 Area A block, offshore Sureste Basin. The well was spudded on early-April 2020, and its stratigraphic target was Lower Pliocene from 1,940 m to 2,060 m. The trap is combined, where the south-west closure is represented by the down dip structure and fault closure on north-west direction. The stratigraphic trap component is represented by facies change in all directions. It had estimated unrisked prospective resources of 47 MMboe with a 51% geological chance of success. The hydrocarbon expected was oil 27Â° API. PEMEX holds 100% interest in this block.  The "Campeche" jack up drilled the well in water depth of 26 m. The estimated total well cost was USD 29.2 million, which includes USD 19.2 million for drilling (39 days) and USD 10 million for completion (32 days).   On 28 August 2019, SENER officially granted the entitlement for this block AE-0150-Uchukil.    On 2 October 2019 CNH approved its first exploration plan.       On 20 February 2020, PEMEX was granted approval by the CNH to drill the Paki 1EXP new-field wildcat (NFW).
