  • METHOD FOR APPLYING THE SCALE INHIBITOR TO COMPLETION FLUIDS DURING INJECTIVITY TEST OPERATIONS
    Publication number: 20240133268
    Abstract: The present invention relates to a method for applying scale inhibitor to completion fluids during injectivity test operations. Said method takes advantage of the completion fluid to inhibit scaling in the reservoir by filling the porous spaces of the reservoir rock with the inhibited completion fluid. When the well is put into production, this inhibited fluid positioned inside the reservoir will be produced together with the oil and will inhibit the formation of scale inside the reservoir and on production equipment.
