The purpose of this report is to forecast the 1985 production possibilities of 21 non-OPEC marginal oil producing, developing and less-developed countries (LDC), in Latin America, Africa and the Far East (including Asia), and the potential net benefit of such production to the world market. The net benefit is the quantity of oil that may be produced in excess of indigenous demand. The forecast is based on an analysis of drilling results in geological basins, and pertinent historical production and consumption trends. The extent to which production is expected to increase hinges on the status of existing fields and the quality of recent discoveries. The normal lag-time between pre-concession or pre-drilling exploration, exploration drilling, development drilling, and the installment of production facilities with ancillary transportation and marketing infrastructure, preclude any oil discovery not now undergoing development from being an important supply source in 1985. In the event national political, social and economic policies rationalize a less than maximum effort to increase production, this forecast becomes moot. The forecasts of others concerned with the future prospects of many of the same countries that are the subject of this analysis, are included for comparison
