Statistical Methods for Evaluating Sequential Material Balance Data [PDF]
, 1979 Present material balance accounting methods focus primarily upon the "material unaccounted for" (MUF) statistic, which utilizes the data from only one material balance period as an indicator of a possible loss of nuclear material. Typically a cumulative MUF (CUMUF) statistic, which utilizes all the available flow data, is also calculated; but there is ...

Fuzzy material balance method to model hydrocarbon field development
Journal of Physics: Conference Series, 2020 Abstract This paper introduces a new approach for modeling material balance of fluid withdrawal during field development in case of uncertainties. The approach is based on representation of the fixed reservoir and fluid parameters by fuzzy numbers.

Dynamic reserve calculation method for gas-condensate reservoirs based on flowing material balance theory [PDF]
Youqicang pingjia yu kaifaThe depletion process of a gas-condensate reservoir is characterized by significant condensation phenomenon. Existing material balance methods often fail to establish a linear relationship between pressure drop and cumulative production, resulting in ...
