IEEE transactions on dielectrics and electrical insulation, 2023
Dissolved gas analysis (DGA) has been a critical technique for transformer diagnosis. DGA is a typical multiclass imbalance problem where most of the samples correspond to healthy state transformers or units.

Analysis of Gas-Cap or Dissolved-Gas Drive Reservoirs
Society of Petroleum Engineers Journal, 1961Abstract A numerical method of solving the partial differential equations which describe the one-dimensional displacement of oil by gas has been presented. Possible extension of the method to treat multidimensional flow is discussed, and the limitations of this extension are indicated.
