| Summary: | Title screen The objective of this project is to choose optimal development scheme of block Z Field Y that is stable for uncertainty in geology. “Optimal” here means “optimal in the mean” that brings the highest EMV. Absolute permeability field and relative permeabilities curves were chosen as uncertainties to investigate. Three relative permeability curves and three fields of absolute permeability were chosen, i.e. totally 9 geologies were involved in selection of the optimal development scheme process. Many calculations of various development schemes for each geologies (absolute and relative permeabilities) were made. Optimal completion type and well pattern were determined. Then there was an attempt to create NPV proxy model by means of spline approximation and artificial neural network. Both methods, based on 27 points for training showed poor results, that is number of training data points (simulation runs) should be increased to obtain satisfactory results. Obtained proxy models helps to assess influence of the Corey relative permeabilities’ parameters to production and therefore to the NPV. Режим доступа: по договору с организацией-держателем ресурса |
