The Norwegian Petroleum Directorate (NPD) has disclosed that approximately 65% of gas resources on the Norwegian continental shelf remain untapped, presenting a significant opportunity for exploration and extraction. The NPD's recent reports indicate that out of 84 gas discoveries with a total volume of 1.27 trillion cubic meters, only a fraction has been produced. The majority of these untapped resources are situated in tight reservoirs, characterized by low permeability, high pressure, and temperature challenges, requiring innovative technologies for extraction.

As of 2022, the NPD's findings reveal a substantial increase in gas volume, surpassing four times the 2018 figures. Despite plans to maintain high-level gas production in Norwegian waters until 2028, a subsequent decline is anticipated. Tight reservoirs pose challenges due to their challenging subsurface conditions, hindering the realization of untapped gas. The Norwegian Sea holds the highest mapped gas volumes in tight reservoirs, particularly in the Tilje and Garn formations, presenting both opportunities and complexities.

In the North Sea and Barents Sea, additional untapped gas resources are located, with specific challenges and potential solutions identified by the NPD. In response to the complexities of extracting gas from tight reservoirs, the NPD emphasizes the importance of implementing measures such as fracturing and multi-branch wells. Slim-hole technology is also highlighted as a relevant approach to enhance reservoir exposure and improve gas flow.

Despite acknowledging the inherent challenges in extracting gas from tight reservoirs, the NPD Director for Technology, Kjersti Dahle, underscores the industry's commitment to maximizing recovery rates. She suggests that higher gas prices could drive the necessary technology development, coordination, and infrastructure to unlock these untapped reserves. The NPD encourages collaboration among project owners, emphasizing the utilization of existing infrastructure for cost-effective development.

Arne Jacobsen, Assistant Director of Technology at NPD, emphasizes the need for companies to think innovatively and collaborate across fields, aiming for potential economies of scale. While recognizing the cost challenges associated with implementing new technology, Jacobsen advocates for proactive efforts, ensuring that the untapped gas resources are not lost and encouraging sustainable exploration practices.
