Revised in February 2018, this is a map illustrating the open and closed blocks gas and oil fields of Mauritania and Senegal. Open and licensed acreage is shown, with block operators marked. Associated downstream infrastructure is included such as tanker terminals and the proposed location of LNG regasification and liquefaction plants and import terminals. The map is a PDF file, made using eps graphics, meaning that there is no loss of resolution as the file is enlarged. Price: £70 or available as part of a full subscription.
