Abstract. The oil and gas (O&G) sector is a significant source of methane (CH4) emissions. Quantifying these emissions remains challenging, with many studies highlighting discrepancies between measurements and inventory-based estimates. In this study, we present CH4 emission fluxes from 21 offshore O&G facilities collected in 10 O&G fields over two regions of the Norwegian Continental Shelf in 2019. Emissions of CH4 derived from measurements during 13 aircraft surveys were found to range from 2.6 to 1200 t year−1 (with a mean of 211 t year−1 across all 21 facilities). Comparing this with aggregated operator-reported facility emissions for 2019, we found excellent agreement (within 1σ uncertainty), with mean aircraft-measured fluxes 16 % lower than those reported by operators. We also compared aircraft-derived fluxes with facility fluxes extracted from a global gridded fossil fuel CH4 emission inventory compiled for 2016. We found that the measured emissions were 42 % larger than the inventory for the area covered by this study, for the 21 facilities surveyed (in aggregate). We interpret this large discrepancy not to reflect a systematic error in the operator-reported emissions, which agree with measurements, but rather the representivity of the global inventory due to the methodology used to construct it and the fact that the inventory was compiled for 2016 (and thus not representative of emissions in 2019). This highlights the need for timely and up-to-date inventories for use in research and policy. The variable nature of CH4 emissions from individual facilities requires knowledge of facility operational status during measurements for data to be useful in prioritizing targeted emission mitigation solutions. Surveys of individual facilities may always require this. However, for field-aggregated emissions, our results show that an accurate estimate of total field-level emissions simply requires a sufficiently large and representative sample of facilities, to yield meaningful comparisons and flux statistics, irrespective of operational status information. In summary, this study demonstrates the importance and accuracy of detailed, facility-level emission accounting and reporting by operators and the use of measurement approaches to validate bottom-up accounting.

Abstract Cementing is the fundamental first step and foundation for well construction. The traditional "let's go, mix it, pump it and bump it" cannot be the standard for the current and future offshore cementing operations. As oil and gas operators continue to push the envelope for both innovation and efficiency in well construction operations, to drive energy transition, lower carbon footprint, service providers continue to look for ways to "do more, with less". The latest innovation is redefining offshore cementing operations with a powerful combination of field-proven expertise, equipment, processes, and software. Remote Cementing Operations, the first of its kind in the industry, offers real- time and remote-operation capabilities, controls, and diagnostics of offshore cementing units. While conventional operations would typically involve a cement specialist working in an adjacent room on the rig, Remote Cementing Operations allows all cementing procedures to be controlled offsite by a cementing SME (Subject Matter Expert) from a Remote Operations Center (ROC), miles away from the offshore rig simplifying the operations, minimize errors and improve reliability. As the industry moves forward with a goal to lower carbon footprint, remote cementing enabled by automation will play a key role to implement innovative technologies that will help operators accomplish zonal isolation today and in the future while improving reliability, consistency and driving efficiency. The new implemented process thus results in reduced costs, risks, and non-productive time (NPT) with fewer personnel on-board (POB)—all without sacrificing quality, safety, and performance. A recent success case study is presented, where in an entire offshore well all the cementing operations have been mixed and pumped flawlessly from the ROC in one of the NCS (Norwegian Continental Shelf) rigs. This work explores the relationship between the process of planning, execution and troubleshooting remotely when performing cement operations. By analyzing and reviewing different previous experiences on remote operations, the authors developed a more comprehensive decision support system for remote cementing operations.

Operational enterprising is gradually emerging as a new solution to manage offshore assets on the Norwegian Continental Shelf (NCS). This is seen as an inevitable step-change with respect to obvious commercial challenges in the immediate future, and thus has become an integral component in the new efficiency leap of oil and gas (O&G) production business. This rapid enterprising solution in principal is based on the use of advanced ICT solutions, and active integration of technical disciplines, experts, and organizations to establish Smart assets. This would eventually allow the offshore assets to be supported and managed on a 24/7 online real-time basis irrespective of the geographical location. It has already begun to break the conventional organizational barriers and has brought an explosive growth in the use of advanced technologies. Current rapid enterprising practice on NCS exemplifies the usability of robust technologies blended with innovative organizational solutions as new frontiers in search of commercial excellence.
