System and methodology for chemical dispersion within a wellbore

A production system disposable within a wellbore, the production system comprising:

• a tubular string disposable within the wellbore;
• and
• a tubular joint coupled to the tubular string and 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;
• a filter section disposed proximate a second end and comprising a filter assembly to filter fluid flowing into the bore via a second plurality of orifices from a second area proximate the filter section;
• a packer disposed between the perforated section and the filter section, the packer operable to isolate the first area from the second area when the tubular string is disposed within the wellbore;
• and
• a chemical dispersion system disposed adjacent to the filter section, the chemical dispersion system comprising a first control line and a first dispersion manifold and operable to disperse treatment fluids proximate the filter section to at least reduce a buildup of blockages along the filter assembly.

A method for producing formation fluids from a formation, the method comprising:

• positioning a tubular string comprising a tubular joint within a wellbore extending through the formation;
• dispersing treatment fluids proximate a filter assembly of the tubular joint via a chemical dispersion system to at least reduce a buildup of blockages along the filter assembly;
• filtering a fluid flowing from a first annulus surrounding a filter section of the tubular joint into the tubular joint via the filter assembly;
• isolating the first annulus from a second annulus surrounding a perforated section of the tubular joint via a packer of the tubular joint;
• and
• flowing the filtered fluid entering the tubular joint into the second annulus via orifices in the filter section of the tubular joint.
