1980s
Although commercial quantities of offshore oil reserves in Ghana were discovered in the 1970s, by 1990 production was still negligible. In 1983 the government established the Ghana National Petroleum Corporation (GNPC) to promote exploration and production, and the company reached agreements with a number of foreign firms. The most important of these permitted US-based Amoco to prospect in ten offshore blocks between Ada and the eastern border with Togo. Petro Canada International has prospected in the Tano River Basin, and Diamond Shamrock in the Keta Basin. In 1989 three companies, two American and one Dutch, spent US$30 million drilling wells in the Tano basin.
