... Abstract The existence of fluid’s compositional gradient in a reservoir drives convective flow which brings significant impacts to the operations, e.g., in formulation of injected fluid for well stimulation and enhanced oil Recovery (EOR). However, fluid compositional gradient is not always...

.... Workflow for confirming the existence of a compositional gradient and characterization of a biodegraded oil column. A novel approach to evaluation of inflow control devices (ICD) and its implementation in the well design. An ICD modelling tool developed specifically for direct comparison of different...

... was produced at the separator. In-situ fluid characterization was not done in this well. Although bottomhole samples were recovered from the testing string, and PVT experiments were conducted on them, no conclusion could be drawn on the probable existence of a compositional gradient (in the absence of fluid...
