Drilling: Drilling Hazard Mitigation Technologies Key in Eliminating Non-Productive Time in Challenging Wells + Overview of the Dodson Database System

Cost overruns can easily manifest during well construction because of unexpected issues including lost returns, differential sticking and narrow pore pressure/fracture gradients. To better plan for potential overruns, operators sometimes earmark 10-25% of AFE to cover the unexpected costs which can significantly affect drilling budgets. Technical and operational risks versus the potential ROI are critical factors in determining whether a project will proceed.


This two part presentation, based on SPE129030 and OTC 20220 reveals drilling challenges that have been encountered and the common practices that were employed to address these drilling hazards. Also this presentation compares and contrasts how these same circumstances have and can be addressed much more efficiently with engineering evaluation processes that help determine the best drilling tool and/or technique to mitigate risks and NPT.  An overview of the Dodson database will describe NPT in various categories, a five year statistical review in different drilling environments and show how these metrics can be used to reduce drilling time.
