Abstract
Methods and apparatus provide for the characterization of injected fluid flow within a wellbore. Particular embodiments include injecting a slurry comprising a particulate material and a carrier fluid into an isolated wellbore annulus and acquiring composite density readings at one or more discrete locations along the annulus while depositing the particulate material. Interpreting the acquired composite density readings provides an evaluation of the placement of the deposited particulate material within the isolated wellbore annulus. A further step may include determining when the slurry reaches each of the discrete locations as indicated by increases in the composite density reading at each of the discrete locations and furthermore, acquiring a maximum composite density reading at each of the discrete locations along the tubular member as an indication of the quantity of deposited particulate material at each of the discrete locations. Apparatus includes a plurality of densimeters secured at discrete axial locations within a tubular member for acquiring composite density readings within an isolated wellbore annulus.
