Revised in March 2018, this is a collection of maps illustrating the open and closed blocks, along with the gas and oil fields, of Ghana, Togo and Benin. There are also two inset maps that provide closer detail of Ghana's offshore landscape. Associated downstream infrastructure is included with oil refineries, tanker terminals and the locations of gas processing and LNG regasification plants, now and in the future. Gas and product pipelines are also included. 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.
