Underbalanced drilling solves difficult drilling problems and enhances production
An alternate approach to drilling, completing and working over new and existing wells has dramatically improved the efficiency of these operations. This method is called underbalanced drilling (UBD). Improvements in both the equipment and technique during the past 5 years have made this process economical and necessary to solve many difficult drilling problems. Additionally, by reducing drilling or workover damage, dramatic improvements in oil and gas production rates and ultimate reserves are realized, resulting in extra profits for today`s operators. This article will detail the advantages of UBD and give specific examples of its applications, A series of related articles will follow, including: new UBD equipment, land and off-shore case histories, coiled tubing drilling, underbalanced workovers, software technology and subsea applications to examine the reality and future of this technology.
