Wellbore Collision Avoidance and Interceptions--State of the Art
–Journal of Petroleum Technology
This article highlights key knowledge that was shared at the SPE's "Collision Avoidance and Well Interceptions Applied Technology Workshop" held in Inverness, United Kingdom, in September. It raised awareness of issues concerning wellbore collisions and interceptions. Planning to ensure that well collisions do not occur during drilling is a complex and demanding task that is often not given the high priority that it requires in drilling programs. Assumptions are made of the validity and accuracy of historical data that is unfounded. Conversely, planning well interceptions when required in operations such as relief wells/drainage intercept wells requires a sound working knowledge of wellbore-positioning technologies and techniques. Wellbore interceptions and proximity placement are becoming critical applications for the development of some reservoirs, specifically tar sands and coalbed methane. Wellbore collision avoidance is entering the daily skills requirement of drilling engineers as they plan more infill wells and more cluster (pad) drilling. Ultimately, demonstrating the knowledge of the borehole position during the drilling process is becoming a regulatory requirement that demands greater understanding by the drilling engineering community and drilling/asset managers.
