Abstract
The aim of this research is finding a metric of reservoir architecture complexity provided by different depositional environments and further study of its relationship with confidence in STOIIP estimation. As a result, the linear dependence between architecture uncertainty in its numerical expression (information entropy) and confidence in STOIIP calculation is established that makes information entropy a qualitative indicator for assessment of system exploration level. In addition, it was found that information entropy has a logarithmic relationship with amount of information (number of wells) that allows predicting the potential contribution to the removal of uncertainty when drilling a new well and statistical assessment the value and justification of exploration work which can increase the efficiency of decision-making.
