  • Drilling developments

    Robert E. Snyder, Contributing Engineering Editor

    Underbalanced drilling research. In the BP Upstream Technology Group’s November 2001 issue of Well Connected, authors Jonny Gent and Richard Reiley, both based in Houston, overview the underbalanced drilling (UBD) project, which was committed to delivering several key items to the drilling community during 2001. These included a candidate selection model and historical understanding of how underbalance wells produce. The project also committed to "promote the uptake of UBD in assets worldwide." The first major event coordinated was the candidate selection forum in Aberdeen during April. This event represented most of the key operators in underbalance, plus several service and consulting companies. Discussions centered on how to select candidates, and production results, concluding that no model then existed to accurately predict how UB drilling / completion improved production / reserve recovery.
