BRU21 & SUBPRO-Zero Conference

Recent developments in the offshore energy sector call for substantial efficiency improvements across all operations, from field development to drilling, production, and reservoir management. How can it be achieved?

Efficiency enhancement: topside, subsea and subsurface will be the central theme of the 2026 Joint BRU21 & SUBPRO-Zero Conference.

BRU21 is NTNU’s Research and Innovation Program in Digital and Automation Solutions for the Offshore Energy Industry. The SUBPRO-Zero Center focuses on enabling net-zero emissions in offshore operations. Both environments share a strong commitment to developing new technologies and methodologies that increase efficiency across the value chain.

The BRU21 & SUBPRO-Zero conference will serve as a dynamic meeting place for industry, research, and academia to connect, share insights, and explore innovative solutions within the subsurface and offshore energy domains.

Conference scope:

Automated and Digitalized Drilling and Well

Drilling and well construction represent one of the highest costs in oil and gas production. Over the last decade, digitalization and automation have been pushing these costs down. This section will present recent developments in this area.

AI, Machine Learning and Digital Tools for the Energy Sector

This session showcases state-of-the-art digital technologies in the energy sector. We invite contributions covering both practical applications and fundamental innovations that enhance design of processes and industrial operations.

Field development: from economic analysis to collaboration

The era of smaller discoveries and aging infrastructure on the Norwegian Continental Shelf calls for new approaches to field development. Moving beyond a project-by-project mindset, the industry is increasingly adopting portfolio and area-based perspectives. This session presents recent developments in portfolio-level economic evaluation methodologies, alongside emerging frameworks for enhanced cooperation within and across license partnerships.

Efficient water management

In this session, we will discuss the current gaps in knowledge and technology that need to be addressed in order to achieve efficient water management in subsea operations. We will also showcase recent work between academia and industry that contributes to closing these gaps.

Improved production and reservoir management

Production and reservoir management are at the heart of oil and gas industry efficiency. This session will cover recent developments in these topics in the overlap of industry needs and latest academic developments.

Towards zero emission

This session explores technologies driving the energy transition within the oil and gas sector. We discuss operational energy efficiency, carbon capture and storage (CCS), and the deployment of net-zero technologies for the low-carbon future
