Overall statistics for Central Southern were severely affected by the civil war in Nigeria, which broke out at midyear, nearly closing petroleum operations that country. Total annual production decreased 12.7% to 146,535,030 bbl. The decrease was mainly result partial shutdown Nigeria. Gabon recorded a 132% increase whereas Angola Congo (Brazzaville) declined 14.6% 19.4%, respectively. No other countries produced oil 1967. Exploratory drilling reached new high 149 wells completed, 24.6% successful. Twenty-six discoveries made Nigeria important also Angola, Cameroun, Gabon, Mozambique. Unsuccessful exploratory drilled Ghana, Kenya, Senegal, Somali Republic, South Africa, Spanish Guinea, Sahara. In 122 development with 74.6% success. wildcat footage 2,326,413. At year end, 27 rigs operating compared 44 beginning year. Party-months surface exploration work were: geology, 57.0; seismograph, 284.3; gravimeter, 36.5; magnetometer, 7.0; photogeology, 60.0; geochemical, 1.0, structure drill, 39.0. Although return normalcy would greatly accelerate activity, moderate is expected 1968 if conditions remain as end
