This paper is dedicated to program module that gives an opportunity to provide automatically the full cycle of probabilistic estimation of oil greenfield development on depletion fr om STOIIP estimation to economic evaluation. A special attention is paid to the selection of optimal decision in geological uncertainties. Lim itations of popular deterministic and scenarious methods of project evaluation and advantages of full cycle of probabilistic evaluation from geology to economics are described. The basis of program module are Monte-Carlo method that uses discrete and continuous distributions of parameters, material balance model, model of decline curve, model of estimation surface facilities and a simple economics model for net present value estimation.
