Determining and tracking downhole particulate deposition
First Claim
1. A method for depositing particulate material within a wellbore, the method comprising the steps of:
- isolating a wellbore annulus defined by a tubular member disposed in the wellbore;
coupling a plurality of densimeters to the tubular member to remain with the tubular member;
injecting a slurry comprising a particulate material and a carrier fluid into the isolated wellbore annulus;
depositing the particulate material from the slurry into the isolated wellbore annulus;
acquiring composite density readings with the plurality of densimeters at a plurality of discrete locations along the tubular member during the step of depositing the particulate material; and
interpreting the acquired composite density readings to evaluate placement of the deposited particulate material within the isolated wellbore annulus.

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.
