On 4 June 2019, participating partner Kosmos Energy announced that the W & T Offshore Inc.-operated MC 800 2S0B0 Gladden Deep well (API: 608074140600) has encountered oil. Without disclosing the amount of pay penetrated, Kosmos said the preliminary analysis of the well and log data indicates that the recoverable resource is expected to be consistent with the pre-drill estimate of 7 MMbbl of oil equivalent gross. The apparent deeper pool pay will be completed as a subsea tieback and brought on production in the fourth quarter of 2019. The well will be hooked up to the existing Gladden field subsea infrastructure that connects to Murphy Oilâs Medusa spar, located about 20 miles (32 km) to the north in Mississippi Canyon block 582 in the deepwater Central Gulf of Mexico. W & T holds a 57.5% working interest at Gladden and operates the project for co-owners Kosmos (20%), Arena Energy (12.5%), and CL&F Resources (10%).  The Noble drillship âSam Croftâ spudded the MC 800 #2 on 19 March and is conducting operations at a drill site that sits in some 3,100 ft (945 m) of water in the southwest quadrant of the Mississippi Canyon (MC) area, about 75 miles (120 km) southeast of the support base at Port Fourchon, Louisiana. The MC 800 #2 well was part of W & Tâs two-well supplemental development plan (S-7865) for Gladden field that the Bureau of Ocean Energy Management (BOEM) approved in October 2017.  Background Information  Currently shut-in, Gladden field was discovered in 2008 by former partner Newfield Exploration Company. Gladden came on-stream in February 2011 and has produced as a single-well subsea tieback to the Medusa spar. It has yielded 5.7 MMbbl of oil, 7.9 Bcf of gas and 16,896 bbl of water into December 2018 when it ceased production. Production flows from an Upper Miocene-aged reservoir found at around 15,800 ft (4,816 m).
