Coiled tubing underbalanced drilling may increase production at Lisburne Field, Alaska

In 2005, BP Alaska began evaluating the application of underbalance drilling technology as a method for drilling multilateral wells in the Lisburne Field. The evaluation process was enacted as a response to three key challenges at Lisburne: 1. Slow ROP through the Wahoo’s hard carbonate formation. 2. Frequent total losses of drilling fluid when drilling conventionally.
