.... Abstract Equation-of-state (EOS) fluid characterization is used to model the behavior of hydrocarbon reservoirs when variation in the fluid composition has a significant influence on the recovery of hydrocarbons. Examples are miscible gas-injection processes, where mass transfer between the injected gas...

... Abstract Defining in-fill drilling locations seems a simple task in natural depletion reservoirs while in special fields like those under miscible gas injection operation is challenging. The aim of this paper is to scrutinize the production and injection of existing wells and derive some extra...

Through a series of experiments, the asphaltene stability envelope and permeability impairment are established for several bottomhole live crude oil and reservoir core samples during pressure depletion and gas injection processes. Using the parameters obtained from the experiments, precipitation...
