The tubular joint may include a perforated section, a filter section, a packer, and a chemical dispersion system. The perforated section includes a first plurality of orifices to allow fluid communication between a bore of the tubular joint and a first area surrounding the tubular joint proximate the perforated section. The filter section may include a filter assembly to filter fluid flowing into the bore via a second plurality of orifices from a second area proximate the filter section. The packer may be operable to isolate the first area from the second area when the tubular string is disposed within the well. The chemical dispersion system is disposed adjacent to the filter section, includes a first control line and a first dispersion manifold, and is operable to disperse treatment fluids proximate the filter section to at least reduce a buildup of blockages along the filter assembly. ## Claims ### Claim 1 A tubular joint installable on a tubular string disposable within a wellbore, the tubular joint comprising: a perforated section disposed proximate a first end and comprising a first plurality of orifices to allow fluid communication between a bore of the tubular joint and a first area surrounding the tubular joint proximate the perforated section;
