Petroleum production in Africa in 1960 attained a new all-time high of 99,672,705 bbls., representing an increase of 139% over the previous year. This gain was due largely to a 7-fold increase in production from Sahara. Producing countries in order of 1960 production are: Algeria (including Sahara), Egypt, Nigeria, Gabon, Morocco and Angola; and 2 newcomers: Congo Republic and Senegal. In 1960, 227 exploratory wells were completed in Africa, of which 25% were successful. Of new discoveries 22 were made in Libya, 17 in Algeria (including Sahara), 12 in Nigeria, 4 in Gabon, and 1 in Egypt. Exploratory drilling was carried out this year without success in Angola, Congo Republic, Gambia, Ivory Coast, Kenya, Madagascar, Morocco, Portuguese Guinea, Senegal, Somali Republic, Spanish Sahara, and Union of South Africa. During the year, 260 development wells were completed of which 83% were productive. The development drilling was largely in Algeria (including Sahara), Egypt, Libya, and Gabon. A total of 3,624,272 ft. of hole was drilled in 1960, an increase of 22% over 1959, and at the end of the year 116 rigs were in operation. Geological-geophysical exploratory work was most extensive in Libya and Algeria (including Sahara). Party-months for the whole of Africa were as follows: surface geology - 623, seismograph - 1,155, gravity - 162, ground magnetometer - 26, air magnetometer - 3. New concession activity took place in Spanish Sahara, Algeria (including Sahara), Libya, Mauritania, and Niger.
