Abstract

Total petroleum production of central and southern Africa in 1965 increased by 93 percent to 113,604,633 barrels, largely as a result of increases in Nigeria and Gabon. Congo (Brazzaville) production declined 15 percent, and that of Angola fell 29 percent. No other countries produced petroleum during the year. Development wells were 87 percent successful, but 99 exploratory wells were only 41 percent successful. Nigeria had 39 oil discoveries, and Gabon had one oil and one gas discovery. Exploratory wells were unsuccessful in Angola, Cameroun, Congo (Leopoldville), Ethiopia, Malagasy, Mozambique, Somali, and Spanish Sahara. Surface geologic and geophysical exploration was greatest in Nigeria. Offshore activity increased.
