ABSTRACT:
A method for improving the efficiency of horizontal wellbore cleanout of a horizontal wellbore drilled from a vertical wellbore, having a perforated liner cemented across the horizontal wellbore. The method includes running a coiled tubing into the horizontal wellbore. A first cleanup fluid is injected down the coiled tubing and a second cleanup fluid is injected down an annulus formed by the coiled tubing and the wellbore. The injection rates of the cleanup fluids in the coiled tubing and the annulus are balanced. The coiled tubing is moved back and forth over the horizontal wellbore.
