Technology Focus

Systems automation is generating considerable interest within the drilling community. Results of extended field operations with these systems were published this year. An offshore deployment in the North Sea shows savings of approximately 10%, with exceptional repeatability and optimization of activities such as breaking gels. An onshore deployment in a factory-drilling environment in the Bakken, using wired pipe, shows good results in delivering top-quartile performance while indicating room for improvement in systems automation.

As systems automation becomes more widespread in drilling, simulators are required to plan, train rig crews, and monitor real-time operations. The role of drilling simulators can only increase in the future, because training of crews must improve for automation. Demanning at the wellsite is feasible only if the remaining crewmembers are well-trained across multiple disciplines. Real-time monitoring using simulators is not new, but it is approaching a higher level of sophistication with real-time calibration and validation of modeled parameters.

Alongside automation, in-depth studies at the field level can produce exceptional improvements in drilling efficiency, especially when planning and optimization use new technologies to drive that improvement. This systems approach to drilling is aimed at better understanding of issues that hinder efficiency, coupled with implementing methods and technologies that are available in the industry to address identified barriers to efficiency.

The thought-provoking papers presented here represent a good overview of these topics in drilling systems automation and drilling management.

Systems architecture is a structure used to describe the hierarchy of digital feedback loops with different latencies that are inherent to any system. For the drilling industry, the system architecture construct is the drilling systems automation, decision-making, and control framework, which is based on the International Society of Automation 95 standard used in many other industries. This structure allows drilling-automation and drilling-management developers to describe the data flow and control in manual and automated systems at different operational levels. One of the recommended additional-reading papers—SPE 178814—describes how this framework was developed to bring cohesion to the highly fragmented nature of the drilling industry.

The recommended additional reading shows the high level of activity, and level of broad drilling knowledge, within drilling automation and management. A special mention should be made of SPE 174920, which was written by the winners of the first SPE Drilling Systems Automation Technical Section (DSATS) drillbotics competition. The drillbotics competition objective was to build a fully automated model of a drilling rig that can drill through an unknown block of rock. The paper is quite instructional and shows the wealth of talent available to the oil industry. Read it; you will not be disappointed. JPT
