Abstract (en)

[origin: FR2775095A1] The operation of delumping is based on the fact that the oil reservoir has only two non aqueous phases (liquid and gas) , allowing fluid regrouping and detailed decomposition calculations to be carried out. The oil reservoir is split into a grid system and aggregate fluid compositional simulation using components and pseudo components carried out. For each grid section, modeling is carried out on the vaporized fraction with the regrouped fluid under constant equilibrium. For each grid step, a molar quantity is produced and evaluation of the detailed fluid composition carried out.
