Business Impact: Achieving desired and consistent drilling performance and loss reduction in deepwater drilling environments.
Technical Objectives: To develop a drilling performance hypothesis to be applied in deepwater environments. To demonstrate the importance of well data review and interpretation of the facts presented. To illustrate that more specific studies are required in this subject area.
Methodology: Data review and analysis of 25 deepwater (vertical)exploration wells. Identify hole delivery loss and analyze causation. Data review and analysis of two deepwater field development. In particular with ref. to the intermediate (build to horizontal) sections. Identify hole delivery loss and analyse causation. Review of over 60 engineering papers, referencing hole cleaning, drillstring dynamic effects, wellbore stability, an top drives in high angle wellbores. To prove from data set that specific drilling engineering and operational practices are proved to deliver desired and optimum results. To demonstrate that unwarranted rotating practices (continuos rotation, backreaming) cummulate to severely impact resulting hole delivery and overall drilling performance. To identify causation effect through data modeling and simulations (e.g. Drillstring mechanics, dynamics, simulation, hydraulic
