This paper is a case history of two successful applications of mesophase technology for wellbore cleanouts and flow back enhancement. The first application was as a remedial treatment after the well’s ESP pumped off and the second application was part of the completion process. Both wells were completed as open-hole horizontal wells, one with expandable sand screens (ESS) and the other with stand alone mesh type premium screens (SAS). Wells in this field are typically drilled with 65 pcf invert oil emulsion drill-in fluid (DIF) and can be as much as 800 psi over balance to formation pressure. The DIF is intuitively managed with respect to mud solids control, so there is no actual QA/QC on the solids management. The ESS completion was treated remedially with coiled tubing (CT) and rotating jet blasters months after the completion. The horizontal well was accessed through a Y-tool bypass that was part of the ESP completion. The SAS completion was treated with CT and rotating jet blasters after running the screen and setting the packer; prior to running the ESP completion, due to casing size limitations for running a Y-tool bypass.
