Patent ID: 8469100

Claim:
A method of providing integrated fluid filtration and recirculation for cleaning fluid used to clean a wellbore, said method comprising: providing (i) an enclosure having at least two rooms, said enclosure comprising a main pallet forming a floor, sidewalls, and a roof; (ii) an electrical power generator located in one room; (iii) a filtration assembly located in the other room, said filtration assembly comprising: a primary filter; a plurality of secondary filters spaced longitudinally from one another and substantially aligned along an axis; a plurality of filtrate lines; a plurality of bypass lines; and at least one waste line; wherein said filtration assembly is arranged for primary and secondary filtration of a liquid stream flowing through the primary and secondary filters; (iv) at least one filtration pump for conveying said fluid through said filtration assembly and wherein said primary filter, said secondary filters, said pump, and said electrical power generator are substantially aligned along the axis thereby minimizing a profile of said filtration assembly; and (v) a main controller for providing control of said electrical power generator and said filtration assembly; receiving a liquid stream into said filtration assembly from a pre-treatment station; 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.
