Charging, petroleum modelling

Several of the commercial simulation programs offer preconfigured complex column rigorous models for petroleum fractionation. These models include charge heaters, several side strippers, and one or two pump-around loops. These fractionation column models can be used to model refinery distillation operations such as crude oil distillation, vacuum distillation of atmospheric residue oil, fluidized catalytic cracking (FCC) process main columns, and hydrocracker or coker main columns. Aspen Plus also has a shortcut fractionation model, SCFrac, which can be used to configure fractionation columns in the same way that shortcut distillation models are used to initialize multicomponent rigorous distillation models. 

Electrostatic Properties in Nonaqueous Media. Although suspensions most commonly comprise particles dispersed in aqueous media, the petroleum industry contains many examples of particles dispersed in nonaqueous media. Examples include precipitated asphaltenes in oil (see Chapter 8) and mineral solids dispersed in diluted froth in oil sands processing (see Chapter 13). Particles can be electrostatically stabilized in nonaqueous media, although the charging mechanism is different (7, 34). In a recent review Morrison (34) emphasized that many models are... 

This paper considers two end-member hypotheses for trap filling one in which the petroleum charge mixes perfectly in the trap as it fills, and another in which it does not mix at all. Clearly, the real world lies variously between these two extremes. Next some model results are compared with field data. Such comparisons suggest that the model that assumes poor...

PETROLEUM CHARGE MODEL, JUDY JOANNE FIELDS... 

A petroleum charge model has been developed for the Judy and Joanne Fields that has allowed a much better understanding of the fluid distribution within the three main reservoir units. 

The charge model has been used in formulating a strategy for infill drilling to develop additional reserves within the Judy Field. Petroleum-water contacts and fluid types are in line with pre-drilling predictions.
