The Brigantine, Caravel, Corvette and Shamrock fields are natural gas reservoirs and gas production facilities in the southern North Sea, close to the UK/Netherlands median line. The fields have produced natural gas since 1999.
The Brigantine, Caravel, Corvette and Shamrock gas fields are located in the adjacent UK Offshore Blocks 49/19, 49/20 and 49/24. Brigantine, Caravel and Corvette follow Shell's convention of naming southern North Sea fields after types of sailing vessels. Brigantine has four gas accumulations designated A-D. The gas reservoirs have the following characteristics.
The gas producing capability of the fields was realised through five offshore platforms, their characteristics are summarised in the table.##2 1 3 7
Gas production from the fields is summarised in the table. Gas from these installations flows to the Leman A complex and from there to the Bacton gas terminal.
The production profile, in mcm/y, of the Corvette field was as shown. <graph>{ "version": 2, "width": 600, "height": 300, "data": [ { "name": "table", "values": [ { "x": 1999, "y": 1782 }, { "x": 2000, "y": 1048 }, { "x": 2001, "y": 517 }, { "x": 2002, "y": 154 }, { "x": 2003, "y": 129 }, { "x": 2004, "y": 471 }, { "x": 2005, "y": 403 }, { "x": 2006, "y": 174 }, { "x": 2007, "y": 39 }, { "x": 2008, "y": 63 }, { "x": 2009, "y": 0 }, { "x": 2010, "y": 0 }, { "x": 2011, "y": 0 }, { "x": 2012, "y": 0 }, { "x": 2013, "y": 0 }, { "x": 2014, "y": 0 } ] } ], "scales": [ { "name": "x", "type": "ordinal", "range": "width", "zero": false, "domain": { "data": "table", "field": "x" } }, { "name": "y", "type": "linear", "range": "height", "nice": true, "domain": { "data": "table", "field": "y" } } ], "axes": [ { "type": "x", "scale": "x" }, { "type": "y", "scale": "y" } ], "marks": [ { "type": "rect", "from": { "data": "table" }, "properties": { "enter": { "x": { "scale": "x", "field": "x" }, "y": { "scale": "y", "field": "y" }, "y2": { "scale": "y", "value": 0 }, "fill": { "value": "steelblue" }, "width": { "scale": "x", "band": "true", "offset": -1 } } } } ] }</graph>
