On 26 November 2019, Kosmos Energy announced it had completed operations at the Resolution prospect at Garden Banks block 491 (G35918) in the Western Gulf of Mexico. Well GB 492 1S0B1 (API 608074083101) encountered reservoir quality sands, but the main objective failed to find hydrocarbons.  On 11 October 2019, the Bureau of Ocean Energy Management (BOEM) approved a revised application for bypass submitted by Kosmos for well GB 492 1S0B1. The well is being drilled by the Seadrill "West Capricorn", which began operations on 2 October 2019. The bottom hole location for the well is located in GB 492. The water depth at the surface location is 6194 ft (1888 m).  On 4 September 2019, the Bureau of Ocean Energy Management (BOEM) approved the exploration plan filed by Kosmos listing 3 wells and 2 mirror locations to be drilled in the Garden Banks (GB) protraction area of the Western Gulf of Mexico at the Resolution prospect covering blocks GB 491 (G35918) and GB 492 (G35919). Kosmos submitted plan N-10070 on 10 June 2019. Of the three non-mirror wells, two have a surface location in GB 492 and one has a surface location in GB 491.Each well is estimated to take 140 days to drill.  On 17 September, the BOEM approved the permit to drill location SL3 in a water depth of 1,888 ft (575 m) using the Seadrill âWest Capricornâ drillship. The well has a surface location in the southeast corner of GB 491 and a bottom hole location in GB 492.  The prospect area is located in the northwestern quadrant of the Garden Banks protraction area, about 233 mi (375 km) southwest from the onshore support base at Port Fourchon, Louisiana. It is about 12 mi (19 km) north of the Occidental-operated Gunnison field which has produced over 66 MMboe by year-end 2018 from Pleistocene to Pliocene age sands. Water depths at the proposed locations vary from 1,884 â 2,073 ft (574 â 632 m).  In a 5 August 2019 investor presentation, Kosmos estimated the gross resource potential at Resolution to be 100 â 200 MMboe. The planned spud date for the well is sometime in October 2019. Kosmos operates the leases with 50% working interest, with the remaining 50% owned by BP.  Bidding alone and without competition, BP picked up GB 491 and GB 492 at Sale 248 in August 2016 with bonus bids of USD 643,726 and USD 619,726, respectively. Kosmos farmed into the blocks effective 1 February 2019 as part of a farm-in package of 18 BP-owned blocks in Garden Banks.
GB 492 001S0B0 (Resolution) nfw. (Kosmos 50% op, BP 50%) in GB 491, lease G35918, was designed to test an amplitude-supported sub-salt prospect in the underexplored western GB area, reservoir quality sands encountered but found water-bearing, well to P&A, WD=600m, TD=7700m.
