    Abstract
  • A new clay-free drill-in fluid, UltraFLO was developed based on the analyses of the advantages and disadvantages of conventional drill-in fluids. UltraFLO has components that are all liquefiable. When used with simple latent acids in well completion, all mud cakes can be made liquid. UltraFLO remains stable at temperatures as high as 140 ℃, and can tolerate drill cutting contamination to 15%. Permeability recovery of cores contaminated by UltraFLO drill-in fluid reaches 89%, and 96% after treatment of the cores with latent acids. Filed application of UltraFLO shows that this drill-in fluid has good inhibitive capacity and lubricity, and is easy to use. Three wells drilled with UltraFLO drill-in fluid had production rates beating estimates.
