The Crosby field in the Gulf of Mexico is expected to come on stream by the end of this year. The 50,000 b/d field is expected to achieve maximum output by the first quarter of 2002. The Crosby field, which is co-owned equally by Shell and BP, is connected to the existing Ursa Tension Leg Platform. Volume from this field is to be pulled into the Mars Blend crude pool. For November, the total pool of Mars Blend crude amounted to 12.7 mil bbl, including volumes from the Brutus field which came online in August. Before the Brutus field came online, Mars Blend crude was derived from oil coming from the Mars Platform, Ursa, King and Europa fields.
