Integrated fluid filtration and recirculation system and method

A method of providing integrated fluid filtration and recirculation for cleaning fluid used to clean a wellbore, said method comprising:

• an enclosure having at least two rooms, said enclosure comprising a main pallet forming a floor, sidewalls, and a roof;
• an electrical power generator located in one room;
• a filtration assembly located in the other room, said filtration assembly comprising:
• a primary filter;
• a secondary filter;
• a plurality of filtrate lines;
• a plurality of bypass lines;
• a plurality of waste lines;
• wherein said filtration assembly is arranged for primary and secondary filtration of a liquid stream flowing therethrough;
• at least one filtration pump for conveying said fluid through said filtration assembly;
• a main controller for providing control of said electrical power generator and said filtration assembly;
• receiving a liquid stream into said filtration assembly;
• conducting primary filtration of the liquid stream through said primary filter;
• conducting secondary filtration of the liquid stream through said second filter;
• adding treatment chemicals to the liquid stream to selectively condition the liquid stream;
• and
• conveying the liquid stream back to the well for subsequent use of the liquid stream in a cleaning operation of the well.

In combination, a system for cleaning a wellbore, said system comprising:

• a coiled tubing dispenser and an amount of coiled tubing dispensed from said coiled tubing dispenser and placed down-hole in said wellbore;
• an integrated fluid filtration and recirculation system comprising:
• an electrical power generator;
• a filtration assembly for filtering cleaning fluid placed down-hole;
• said filtration assembly including a primary filtration station and a secondary filtration station;
• at least one filtration pump for conveying said cleaning fluid through said filtration assembly to filter said cleaning fluid;
• a main controller for providing automated control of the electrical power generator and filtration assembly;
• a fluid transport line interconnecting filtered cleaning fluid from said filtration assembly to said coiled tubing;
• and
• a return line communication with said wellbore for returning used cleaning fluid from the wellbore to said filtration assembly.
