Automated well planning

Digitalization of the drilling process gives new opportunities. A novel framework for automatically generating drilling programs to support both automated and autonomous drilling is being developed. 

Challenge

Well planning often requires significant time and resources across various disciplines. Today the drilling program is normally static and with one solution with possibly a couple of back-up plans. When unexpected situations occur, there will be deviation from the plan and the plan is no longer valid. The new framework facilitates for an ensemble of possible drilling designs, using information from both the planning phase and the operational phase. 

Invention

With Automated Well Planning we go from static and manually generated drilling programs to automatically generated dynamic drilling programs designed to support decision-making during well construction with advanced automation systems. This new approach shifts the drilling program’s focus to a set of adaptable strategies and tactics linked by an overarching plan. These strategies and tactics can assist decision-making during well construction when actual downhole conditions deviate from expectations. The framework captures and propagates uncertainty throughout the entire process. The method promotes collaboration among multidisciplinary teams, enabling each discipline to share, clarify, and justify its constraints. This collaborative approach allows teams to prioritize constraints and design parameters collectively. 

Value

The automatic generated drilling program can be a game changer towards the industry vision “plan a well in one day and with high quality”. In addition to the time-savings in the planning phase, the value of having an automated updated and valid plan during the well construction phase, has great potential for reducing incidents.  Additional value can be obtained by having seamless integration with the Automated Drilling Operational Plan and the execution phase.  

Status

  • The problem of generating ensemble of solutions in the context of automatic well engineering is complex. By using a microservice architecture, one has a versatile framework to generate such ensemble of solutions. A first version of the drilling program will be finalized in 2025. 

Next steps

  • Perform case studies with AkerBP and Conoco Phillips 

Possible commercialization options

  • Enable one or more players to commercialize the software. 
  • Make the microservices available as open-source.
