Block partner Medco in its July 2020 exploration report indicated that the Juum 1 NFW, on CNH-R02-L04-AP-CM-G01/2018 (Block 10), has been abandoned as a dry hole. Medco revealed the total exploration cost for the well totalled US$ 45.5 million, of which US$ 9 million was net cost to Medco. Pre-drill planned total costs were estimated to be US$ 76.3 million.On 20 June 2020, the "Maersk Valiantâ drillship departed from Juum 1. The drill ship arrived on 6 May 2020, likely spudding shortly after. The Repsol Exploracion Mexico operated Juum 1 was targeting 221 MMboe in prospective resources in the Miocene (3,335-3,600m) and the Oligocene (4,050-4,385m). The vertical well had a PTD of 4,460m. The well was planned to take 72 days to drill and plug. The well is sited in 1,755m of water depth. Repsol used the same rig on the Polok 1 and Chinwol 1 NFWs, on the Repsol-operated CNH-R02-L04-AP-CS-G10/2018 Block (Block 29). In January 2020, Mexico's ComisiÃ³n Nacional de Hidrocarburos (CNH) outlined Repsol's plans for a two-well programme on operated Block 29, which would utilise âMaersk Valiantâ for batch drilling (originally planned for between March and June 2020), leaving little time for drilling on Block 10, which presumably lead to the one-well option being exercised. In early February 2020, Maersk Drilling confirmed a one-well option under contract with Repsol.Repsol had identified two prospects on the tract. They are the drilled Juum 1, and Lool 1, a Jurassic Age prospect targeting prospective resources of 101 MMboe. Lool 1 has objectives in the 4,400-4,750m interval, while Juum 1 was targeting light oil (35Â° API). Investments are expected to reach just over US$ 150 million through 2023. The CNH in June 2019 stated that one well will spud in 2020, while the other will spud in 2021, without providing an exact timeline.
