... rates would have provided a different flow profile compared with normal operating rates. As a result of deploying DFOS, data could be acquired at more realistic rates. Through performing thermal inversion of the DTS data and analysis of the DAS data a more accurate flow profile was achieved...

... Abstract A well intercept operation has the scope to drill into an existing well. Similarly, some infill drilling operations are conducted with the scope of avoiding interception with other wells. A prototype of a tool for Active Magnetic Ranging While Drilling (AMR) without the use...

..., and sustaining operational digital twins, that is designed to maximise the asset owner's return on investment by putting the necessary focus on the people, process, and data elements, as well as addressing the technology. A review of project lessons and industry findings will be presented to outline common...

... Abstract As political, environmental, and social pressures build, oil and gas operators are searching for ways to effectively reduce methane emissions. The first step to emission reduction is to understand the current state of facility emissions, which is typically estimated using bottom-up...

... specification ( Table 1 ). Thus, characterising all the impurities and determining the required purity of the CO 2 mixture is critically important for the safe design and operation of CCS transport and storage systems. It is important to note that CO 2 specifications relate to normal operations. Short-term...

... intervention requirements for the subsea oil producers and water injectors, based on historical operational data captured for the wells on this deepwater field. The specific activities for the study were: Collect data for the wells and run component reliability analyses. Wells were initially designed...

... operation cable requirement onshore grid substation Background Oil and Gas Demand – Summary UK and Worldwide Oil and gas continue to represent a substantial portion of the world's primary energy mix. Oil has typically accounted for around one-third of the global primary energy mix...

... Abstract Using a remotely operated vehicle (ROV) to access annular spaces within a subsea multi-string wellhead avoids HSE risk and subsequently reduces the cost and time associated with abandonment operations compared to that of typical rig workovers and diver-assisted repairs. This method...

... operated vehicle (ROV) was used to apply suction to install the unit. The inclination of the well foundation was manipulated by adjusting drillstring tension and skidding the drilling package to apply horizontal loading. The unit was successfully installed with the observed inclination and penetration...

... confirm that this robot will ease the pilot's job and help the operator to make more accurate detections of the jacket integrity. The robot control system can operate in either a First Person View (FPV) mode where the pilot has full and easy control, or the robot can operate in closed loop mode where...

... occur when key parameters deviate from safe operating conditions, leading to downtime and loss of production volumes. To address this challenge, the objective is to establish repeatable frameworks for constructing predictive models through the utilization of deep learning algorithms. These models...

... Abstract Building robust and trustworthy digital twins that can be used for critical operational decisions is a key industrial challenge. As a response to this challenge DNV has developed a suite of recommended practices for development and assurance of digital twins, with the principal DNV-RP...

.... Modelling of such processes is important for operators to be able to design as Underground Hydrogen Storage (UHS) properly for HSE reasons especially considering some reservoirs may be prone to reservoir souring due to biochemical reactions with hydrogen injection. The simulation model used in this study...
