Abstract

In high profile applications, an advanced drillstring dynamics modeling system has been used to mitigate downhole vibrations and improve penetration rates (ROP). The capability of virtually drilling a well with computer software allows the engineer to identify the root causes of damaging vibrations and ROP limiters before drilling commences. Consequently, the conventional trial-and-error methodology can be replaced by a cost-effective optimization process. This technology provides an efficient platform to optimize the total drilling system including bit selection, bottom-hole-assembly (BHA) design, operating parameters and the placement of individual BHA components. The utilization of this software has delivered significant economic benefits associated with increased total footage, higher ROP and fewer downhole tool failures.
