On 28 July 2020, CNH reported abandoned dry the well Max 1 EXP directional new-field wildcat (NFW).The well was drilled by Shell and is located in the CNH-R02-L04-AP-CS-G02/2018 contract, Area 21 Block in the ultra-deep-water Campeche Deep Sea Basin, spudded on early May 2020. Shell is operator of the contract and holds 60% working interest and Chevron holds 40% working interest.  The NFW had a proposed total depth (PTD) of 7,480 m measured depth (MD) and 7,332 m true vertical depth (TVD) and was planned as a Type S directional with a maximum inclination of 22.46Â° in the section 3,690-4,026 m, Lower Miocene and Upper Oligocene, and then drill back to vertical below 4,026 m. The primary target was the Upper Jurassic Oxfordian from approximately 6,970 m to 7,100 m with the analog being the Jurassic Norphlet in the northern Gulf of Mexico or the productive reservoir in the Ek-Balam fields in the Sureste Basin.  The NFW is in the north-eastern area of the block, nearest well is Chibu 1EXP located approximately 31.2 km north-west and the nearest historical well is the Tamha 1 plugged and abandoned (P&A) by PEMEX in 2008 located140 km south. The prospect trap is a north-east south-west oriented, salt nucleated anticline. The Max prospect has estimated unrisked prospective resources of 291 MMboe with 14% of Geological Chance of Success. The hydrocarbon expected is oil 26Â° API.  The "Deepwater Thalassa" D/S drilled the well in a water depth of 2,511 m. The drilling cost for the well was estimated to be USD 84.8 million and the abandonment cost was estimated to be USD 7.0 million.  On 7 May 2018, Shell was granted an official award for the CNH-R02-L04-AP-CS-G02/2018 contract, the 2,048.35 sq km, Area 21 block (alternate block name AP-CS-G01).    On 13 June 2019, Shell was granted approval by the CNH for the first exploration plan related to the CNH-R02-L04-AP-CS-G02/2018 contract, Area 2, that includes geophysical and geological studies as well as the drilling of one firm commitment exploration well with an incremental case of drilling a second exploration well.        On 13 February 2020, Shell was granted approval by the CNH to drill the Max 1EXP directional new-field wildcat (NFW),
(Campeche Deep Sea B.) Max 1 EXP nfw, operated by SHELL (60%), CVX (40%) in the CNH-R02-L04-AP-CS-G02/2018 contract, Area 21 Block, WD = 2511 m, reported abandoned dry.
